The new EVO64 C64 Replica Board

[@PureAudioTones]

Even though it is quite expensive for an ordinary C64 fan, I am very delighted to see such products entering the market. Actually, it is unbelievable a computer 40 years old still get upgrades 😄 Thanks for the review Jan, so far the best review I have watched.

[@jantestowy123]

The best video on EVO64 on the Internet hands down! Klasse gemacht!

[@CaptainLazy99]

Oh my G! NuTube sounds so awesome! Thanks for this video Jan.

[@milk-it]

You did a real justice to demonstrating the sound in the EVO64 board! I upgraded my pre-order to include not only the NuTube64, but the Triode64. I've still got my original C64 which works flawlessly, and the demonstration you provided here gives more depth of sound and clarity without distortion compared to the original. The rest of the deep dive into the configuration is much appreciated and sadly lacking from another KZbinr's video I recently watched. Danke Dir!

[@auro1999]

Milk-it, Send an email to Darrell and explain your position. I have some different ways to to the triode64 and I might need some extra ears for testing. Are you in USA ?

[@bwack]

Yeay! Thanks for the mention. When I was contacted at the beginning of the EVO64 project, it was and still is a great honor for me that someone is taking inspiration from my design files :)

Bwack. While there is little or nothing left of your original project. I want to OPENLY thank you for bringing me back to the old EE hobby. I`m EE but I work as materials scientists developing materials for optics and electronics. Thank you BWACK, you rewinded my age of a couple of decades. Stefano.

You contributed so much to the scene over the years, it's just amazing. You actually deserve many more shout outs than you get, I guess. :D Thanks for all your work and especially for making it publicly available so others can use it and expand on it (like with the EVO)!!

[@Colin_Ames]

Jan, this is an outstanding review, much more in-depth than another one made by someone who shall remain nameless! I have never owned a C64, but enjoy seeing content related to it, both repair videos and ones such as this, showcasing modern interpretations. I am not an audiophile, so am not qualified to comment on whether the $500 and $1000 add-ons are worth the money. Obviously you were impressed, and I give kudos to the creators for satisfying a niche market. I wish them success. I also look forward to your followup video where you create a synthesizer.

[@JanBeta]

Thanks! I tried to do the EVO justice. As I said, I would probably not buy it if I hadn’t gotten the review unit myself. But I’m sure there are people who have enough cash and who can make good use of it! I ordered a MIDI cart in the meantime for the synthesizer project, hope to start with that soon. :)

I cannot say which SID is ultimately better, but I’m amazed at how great they sound together. Great video as well.

[@JanBeta]

Thanks! Yup, the different SIDs all sound great in their own right. I particularly like the muffled and flawed qualities of the 6581s but as you said, together they sound just awesome. :D

[@Skizziks42]

I would really like for them to incorporate this into VICE.

[@kaitlyn__L]

Together they have such a fat sound. The subtle differences in envelope response time, filter cutoff slope, etc yield the same kind of slight differences between each side that many fancier synthesisers spend ages meticulously programming in.

[@OzRetrocomp]

I get the appeal of the EVO64, as it seems like a decent replacement C64 board. However I struggle to see the point of the pre-amp options (especially the Triode64). Maybe that says more about me than the target market. Either way, it's great to see people are still pushing the C64's architecture to new limits over 40 years since it was released.

[@StepDub]

I sold my C64 to finance an Amiga 500. The Amiga was fantastic and helped me to move forward in computing, but I never felt the sense of wonder, excitement and discovery that went with the 64. I never thought that I would see the day when we actually had a choice of new implementations to choose from! Happy days again.

[@rosariodagosto6484]

Nice new c64 board .love the filtering on board 😊

[@DavePoo2]

This got me thinking about how dual SIDs work. I know the C64 memory map has the SID registers repeated 32 times, so I suppose when Commodore designed the machine they maybe thought that they could support as many SIDs as they could get on the board (up to 32), and maybe they weren't sure how many channels they would be able to design into the single SID chip, they might be able to "multi-core" the SID so-to-speak. But then the actual C64 only has the single SID chip select line supported, so you can't just slap in another SID without changing more of the chip select circuitry (U15 chip selects the SID when the appropriate address lines are being accessed?). I assume these new boards have designed in the multi SID support? and I also assume that it's possible to put more than 2 in, but I've never noticed anything about triple SIDs or quadruple SIDs?

[@C64EVO]

The board is clearly supporting 2 physical SIDs, although if using an ARM2SID or FPGASID, it should be possible to support even more

[@TomStorey96]

It's probably not that they intended to put multiple SIDs in, but more that they just simplified the address decoding for a few chips (the same decoder also selects the colour RAM). Each of the devices (VIC included) is given a 1K block of memory to live in as a result of the colour RAM needing that much space. I guess they could have decoded further, but that would require more chips.

[@michaelmadsen4923]

48:37 "But you probably have something else to do" Trust, me. Anyone that watches your channel does NOT have anything else to do and could also listen to SID music all day long :D

[@darkman042]

44:49 The new tube tracks trigger my surroundsound on my home theater!

[@JanBeta]

I would guess it does that because of the slight phase variations between the different SID models. The early implementations of surround sound were using phase-shifting to get the additional channels. Not quite sure if that is still used for the modern digital Dolby surround stuff but it probably still is implemented in most surround devices. :D

[@CubicleNate]

I think the Evo64 is a great project because it does answer the question about what the Commodore 64 would have been like if higher quality components were used in its manufacturing. I love that it further extends the life of the 1980s platform. I wonder what the next steps are... as in, where do we go from here? This almost demands that the platform get extended further. Some kind of expectation for Dual SID and with the new VIC replacement that also extends the C64s capabilities, I would like to see some sort of... not quite next gen C64 but something that we can all enjoy, no matter the vintage of Commodore 64... Perhaps I am babbling...

[@a4000t]

Higher quality? the many original c64's have survived 40+ years now. It's incredible for a computer designed to last 4-5 years.

[@lordkaosny]

Great video. Where did you get the C64 A/V adapter at 35:00? Are you happy with it?

[@avrilcadabra]

As a musician I don't think I am the target audience for the amp, we use studio reference monitors over consumer speakers to hear every bit of articulation and detail, so if you are using a 64 to natively write music on or as an instrument like you mentioned you want the most accurate reference point, a 64 plugged into reference monitors. The tube amp is removing some of the clarity and ability to hear the detail in how extremely fast the sid chips parameters change. If I did specifically want this tube sound afterwards there is a plethora of options including nutube pedals and preamps from Korg or something like an Elektron analogue heat which is going to give you a tonne of control and options that you can use on all your gear. It might make more sense for people who have no need to invest in studio gear but want a smoother more glued sound from their 64. That said it looks like a great board and the amps are totally optional, so win win for everyone.

[@JanBeta]

Good point! I was thinking that it would make sense in a live setup for musicians or as a standalone synth in a recording setup (which is probably what I’m going to use it for primarily). Definitely not for everybody but I don’t think that’s the intention of the project. ;)

[@Nordischsound]

Cool, C64 will never die 🥳

[@OscarSommerbo]

It will since there are still chips that has no modern replacements. And you get into the ship of Theseus if you use HW emulation for the sid and vic2. But then there are cycle perfect emulators, so maybe by that token it will never die.

[@dougjohnson4266]

These boards seems to be making it around to the channels. I am very happy with my MK2 but the EVO64 looks cool.

[@tommyovesen]

[@monchiabbad]

The big "chip" with the glass window and the two glowing laghts is the real tubes.

[@JanBeta]

You could say that. It’s VFD "tubes" that are used to resemble a real tube/valve sound. Works pretty well in this case. The same technique is used in a plethora of outboard preamps and audio effects devices.

[@bluehatguy4279]

I have a brother-in-law that is a musician. The cost might stop me, but I am kinda curious if he would enjoy receiving one of these as a gift. I'm curious what music making software exists that would take advantage of the fancy dual sid hardware.

[@borayurt66]

This is a great project that I have been following for some time. Every extra feature that is put in the board is a great choice, it contains most of the essential fixes / enhancements that were implemented to old C64 in time. I only have 2 criticisms; first being the price. I understand the effort and time that went into the project, and I am aware of the parts quality used. I also understand that considering the expected sales number, they had to make it a bit pricey to cover everything, but still, not an easy money to pay from a hobbyist's perspective. Second is the decision to embed a modern PLA replacement on board. No one, even the creator can guarantee 100% compatibility for a modern replacement. There should have been another ZIF socket for the PLA and the choice of placing an original PLA or any of the modern replacements in that socket should have been left to the end user. Other than these two, I think it is the best modern C64 board ever created so far, and I don't expect that there will ever be something better.

[@C64EVO]

The production board that will ship on Feb 15th has a modular and removable QAPLA’ (PLA).

[@auro1999]

Bora. The QAPLA was moved off board with a small square socket to allow me to change CHIP, to add funcitonalities (in the EEPROM) and to be able to play with more possible waiting states in production SRAMs. Compatibility is always goal. I promise you that when your QAPLA dies, you will have a replacement, ready to take its job.

[@spacedock873]

Saw the 8-bit Guy's review of this board. The main board is excellent and is definitely worth considering for any C64 fan who wants to have a future-proof machine with modern components. The sound cards though - Ouch! I know it is impossible to make a valid comparison over KZbin due to sampling, compression and reconstruction but seriously?! However you process it in the machine this is still 80's vintage 8-bit sound generation. You might as well connect your NAD amplifier to a gramophone! $500? 😲 $1000? 🤣

[@C64EVO]

The available preamp modules are a niche offering for enthusiasts that want to experience them. They're not required for base functionality of the board. The cost for the modules is a reflection of the very high quality components, as well as the time and effort it takes to assemble, calibrate and test each module by hand (yes each is handmade). We're not expecting to sell tons of them, but we really wanted to have them for ourselves and to share them with others that might share a similar interest.

[@spacedock873]

@@C64EVO I am sure that the cost of the boards reasonably reflects the time and expense required to develop and produce them and I applaud your achievement. My doubt is whether it was really necessary (or sensible) to spend this amount of time, money and energy developing and building modules to amplify 80's 8-bit sound in the first place! The 8-bit Guy's final verdict was that the VFD module produced little if any improvement over the basic board and certainly did not justify paying $500 for. I suspect that the same will apply doubly to the $1000 board. Producing it for yourselves is one thing and offering it for sale is the next step, but in a time of global financial crisis the prices do seem rather laughable.

[@C64EVO]

Giving all due respect to David (The 8-Bit Guy), we love his contributions to the retro world, however he made it quite clear that he does not consider himself to be an effective judge of something as subjective and personal as audio quality. His attempt at a putting together a quantifiable set of measurements was quite limited. Comparing the waveforms actually has no meaningful relationship to the sound character, which needs to be experienced to be appreciated. I don't think David would disagree with anything I've said there. You'll notice that Jan is sharing a quite different subjective experience in this video, which we certainly did not ask him to do. Other than providing him with the board, we did not otherwise sponsor or attempt to influence his opinions in any way. Obviously we think it would be great if others choose to experience and enjoy the preamp modules in the same way that we do, but leaving them as a separate option makes this a personal decision for each hobbyist.

$1000 for a tube amp? It's a lovely project, but that is absolutely insane, I've got a little desktop tube amp (MC 84-C) with 6 tubes that costs less. Sorry, I don't want to be "that guy" but I think the pricing for this one is a bit aggressive. Cool project, but a little much for me.

[@JanBeta]

They are using studio grade components on that tube board afaik, so it's not really comparable with a consumer grade product (which I assume your preamp board is). Effects rack tube preamps for recording studio applications are usually in a similar price range (and well above that). I think they are definitely marking up the price to make a bit of an income from all the work they put into this but I would guess it's not as hilarious as it seems. It IS super over the top connecting something like that to a humble C64 but I kind of love the insanity of it (although I would definitely not be able to pay 1000USD for it).

Although there seems to be a slight positioning issue with the audio jack on the preamp board if you put it in a C64C case (the connector doesn't quite line up with the cutout in the case but you can work around that by using slightly smaller standoffs for the preamp board). Breadbin case fits 100% fine.

Yes, the 8580 has some flaws of the previous versions fixed. It's generally a lot cleaner sounding than the 6581. Both have their pros and cons I think. A matter of taste. The SID was superior to pretty much everything else at the time I think, mostly due to the fact that it was designed by Bob Yannes who was a synthesizer designer really and had not designed any ICs before. So it was a kind of a happy accident that he started designing something more ambitious than usual because he lacked the knowledge about the restrictions (afaik he originally planned to design the SID with a lot more voices and filters but had to downsize it to 3 channels in the end). :)

The FPGA Sid uses Dual Sid can you explain that sometime

[@JanBeta]

Oh, I think the way it works is that it's just "listening" to the standard addresses that the regular "physical" dual SID mods usually use. The FPGA allows for two SIDs to be emulated at once. The ARMSID is able to do the same. It's just a matter of running an extra connection to the output jack to get the stereo effect. :)

How does this compare to an ultimate 64 elite? To me, it seems like the only added features are those that come sith the expensive sound additions.

I don't have an Ultimate to compare it to unfortunately. Performance should be pretty much the same (minus the preamp options, plus the nice menu and other options the Ultimate offers). It's a different approach though generally. The Ultimate replaces most of the original circuitry and MOS chips with FPGA implementations of them, the EVO uses the original chips so it's closer to its heritage. It's a matter of preference I'd say. :)

[@C64EVO]

EVO64 is attempting to remain very authentic, paying tribute to the original C64 design, by supporting either the original chips or modern alternatives, whereas the U64 is fully reimplementing all of the chips in its FPGA. There's no right or wrong approach, it really comes down to taste and style and personal preferences.

[@christianlarsen1070]

@@C64EVO I understand the hardware differences (I have a U64e), but am just keen to understand whether the EVO offers me anything additional

[@C64EVO]

@@christianlarsen1070 well EVO wasn't designed to compete with the likes of the U64, so there was little compulsion to reach feature parity with an FPGA system. The design goal as states above was to achieve the best quality from the original system architecture (and chips). From that perspective, we feel that we've achieved our own goals. Hopefully that lends perspective.

Jan that cut on your thumb looks bad. Make sure you cover it up so you will get no infections .Great vlog Jan

[@JanBeta]

Oh, it's nearly healed now. It looked worse than it was, just a surface scratch really. :)

[@KAPTKipper]

NuTubes are known to be microphonic. Does tapping the board affect the noise?

[@hicknopunk]

I'd buy one of the aftermarket mounting solutions, just to be sure.

[@C64EVO]

I'm sure you want to hear Jan's response to that question, but I can add that the mounting solution that has been implemented for EVO does already include vibration dampening, which should resist microphonics under basic movement conditions, like using the keyboard. It would take a more abrupt and deliberate type of system jostling to cause any discernible microphonic noise to enter the signal.

[@hicknopunk]

@@C64EVO oh good!

[@auro1999]

1) no if you type on the C64 2) no if you tap the board 3) yes if you tap the nutube. The device is NOT mounted flush with the board but elevated of 2-3 mm, to reduce vibration. As the guy below says, it is possible to put a foamy support and a flex connector

[@hicknopunk]

@@auro1999 nice

[@RetroNowTV]

This is such a lovely board and those ZIF sockets are amazing. I know I can't justify the premium cost of this, but I suspect that won't stop me adding one to my collection in the long run. To be honest I've already started saving my pennies. 😉

[@JanBeta]

Yeah, it is an amazing board indeed! The price is kind of justified in my opinion (while it's still way over my budget -- but I am lucky enough to have gotten one for free). :D

I have a mint looking c64 and floppy drive. The caps need replacing but I can tell I'm the first person in it. I have the original manual too. I don't want it. All I want is around 50 bucks to pack it while the person pays shipping. I have no where to put it

You really need to build one of them ATX64 boards that are developed by a German. It is like a Sixtyclone, but taken in a completely different direction.

[@JanBeta]

I actually have the C64 tower board from the creator of that one here but didn't get around building that yet! The ATX64 is something I'm super interested in, too. I think I'm going to get one of those sometime!

[@brostenen]

@@JanBeta We are not that many who own a fully build one. Personally I am figuring out how to create a case from scratch for my ATX64.... But you should really do it. Build yours. It is a wierd an unique machine. If you do it, then perhaps mod the ROM's to fitt your build, like I did with the info screen at the top, when powering on.

Oh, a combined Amiga-Atari system would be awesome indeed. It would also help settle the Commodore/Atari feud forever probably. :D

[@twocvbloke]

Can't say it's for me, given how much it costs to acquire a decent (and working!) C64 these days, even if it's to chip-harvest, it would make it way too expensive for my pocket, and that's not including the tube amps (which personally I don't get, but I never have done with tube amps in general anyway), and besides, someone would need to manufacture a smoked-clear topped case to give it the looks it'd deserve, which I guess would also add to the cost... :P

[@JanBeta]

Yeah, it's definitely not cheap! As I said, I probably would not be able to justify a purchase had I not been given this for free.

@@JanBeta I think the AI is on to something :) I remember Amiga's downfall due to Mehdi Ali, which reversed basically says I laid 'em. And they say it all stupid conspiracies...

[@OscarSommerbo]

They did fix a few layout issues and minor HW bugs. What Jan has is pretty close to the final version. But I think the whole project is an exercise in futility. The stated goal of reproducing the C64 with tube amps and fine-tuned video circuitry is a masturbatory exercise. The video and audio will never look/sound as good as we remember it, because memories are unreliable and change every time they are accessed, so no modern day reproduction can compete with nostalgia. And making an "audiophile" C64 is just laughable, on so many levels. But people are free to spend their money on this finely crafted wank.

[@LossMiImKraut]

You don't need to buy it. ;) To each his own. ^^

[@zulucain]

You can get it without that x-ray generator tho

[@milk-it]

I did feel the sound on the EVO64 lacked distortion and had a depth, which were missing from the original C64 that I fired up just after watching this video. I'm parting with my cash for the EVO64, mainly because I want to support the rebuilders and keep such projects alive.

[@OscarSommerbo]

@@milk-it Go for it. I in no way intended for anyone to not buy it, if they feel it is worth it. Just that some of the distortion was what I appreciated, and that the concept of an audiophile C64 is deeply silly, again to me. Tastes will always differ.

[@milk-it]

@@OscarSommerbo I don't disagree with the point about the concept of an audiophile C64 being silly, that does seem somewhat overblown for an 8-bit system! Nevertheless, I still think the huge effort made by the developer deserves a tick.

[@stephenkennedy6358]

IS THE VIDEO ON THE EVO NOTICEABY BETTER THAN THE RELOADED BOARD?

[@auro1999]

yes, that`s the reason I built it

[@JanBeta]

The Reloaded has the same output quality like an original C64 (it just adds a couple of extra options for connectors so you don't have to use the original DIN socket for video output), the ClearVideo on the EVO board definitely improves the output quite a bit if you set it up correctly.

[@holleholl3057]

Sure a project from die-hard C64 fans with the idea of bringing almost every modern mods and tweaks in that you can have. However, the C64 has turned 40 last year and I think that it is sure worth trying such a project from a creative point of view, but personally, I wouldn´t want it. I am doing fine with my box standard system with new caps and the "usual" stuff from back in the day....BTW: there is a Pioneer multimedia system "SPH-EVO64DAB - Car Entertainment Multimedia Receiver" available...sure doesn´t have anything in common with this piece of hardware...

In addition to replacing all of the original ceramic disk capacitors, there are also quite a few caps being used in the audio signal path, to provide smoothing consistency.

[@auro1999]

Tom, I`m proud of it, and I still think I did not go all way I should have. When you put the ultra-low-noise 5V step-down there is ABSOLUTELY no hum in the speakers. And the new ultra-low-noise 24-36 step up - which I use to drive - and overdrive - the nutubes is even better.
