Lets build a TF1260 with a trip to Amiga Ireland

[@crumpster567]

Was a pleasure to meet you at the show Glen and thanks for showing me the EATX, that’s a cracking machine.

[@CRG]

And great to meet you too, it was a fantastic weekend, already looking forward to next year. Glad you liked the 2000, I've got a few things planned for it for later in the year, few expansion cards to build.

[@TheRetroCollective]

So pleased you got this going Glen I was feeling for you at the show! The excitement when it sprang into life 😆

[@CRG]

Thanks Neil. It's a shame I couldn't get it working on the day but glad its working now and yes perhaps a little too excited but that's the fun bit isn't it, seeing the thing you built spring to life for the first time! It was great to meet you at the event.

[@ddniUK]

Great job Glen. Infectious enthusiasm when the card sprang into life. See you at the next show.

[@CRG]

It is a great feeling when it finally works. its a shame I couldn't get it going on the day but at least its working now. Had a great time in Athlone and already looking forward to next year. I'd still like to organise something small up here again for later in the year but I'll keep in touch and let you know.

[@UpLateGeek]

Most people only need a few micro-Pauls of flux to solder surface mount packages, but you're the first person I've seen who uses multiple Pauls!

[@CRG]

We can't all be Louis Rosemann. Flux is cheap, plenty of it helps the solder get where it needs to and I'd rather be looking at it than for it, but I'm not an expert. At least it works though...

[@gavinc5255]

Great going Glen and great to meet you in Athlone! You got an 060, that’s some speed 🙌🏻

[@CRG]

Was great chatting to you at the event Gavin and yes its awesome to have an 060 😁 Such a simple fix in the end too so its a shame I didn't try to reflow the ram down there but at least its working now.

[@TheSudsy]

I have my TF1260 arriving next week and a 060 EC 60 seperately, so good video and very timely.

[@CRG]

Cool, enjoy you're super fast accelerator. The EC chip doesn't have the MMU but you'll still need the 060 libs. Get them from aminet.

[@ArmpitoftheGiant]

Great video as always, but don't use thermal pads to hold those heatsinks in place. The pads are meant to be held in place by mounting pressure so they will fall off. You'll need either thermally conductive glue or double sided tape that is thermally conductive (pretty cheap from Amazon).

[@CRG]

I'll take a look for some thermal double sided tape, wouldn't want to glue them on just in case I need to take them off.

[@fredyelranger]

Great vid as always! My soldering has improved immensely since I started watching your channel. I've also started referring to "wee capacitors" and things being in "a bit of a state" as a side effect :)

[@CRG]

Great to hear, been building anything nice?

[@hiteck007]

Ahhh good times, I never seen so many Antiques in working order. If only Amiga wasn't mis-managed back in the day. I haven't turned on my old Amiga for a good 12 - 15 years now, the poor thing.

[@weepingscorpion8739]

Great video as always. Great job on the accelerator. Now I don't speak Scottish Gaelic but if my googling and Wiktionary skills are any good then Stephen Leary has put something of a joke on the board. And as a language guy, I always appreciate things like these. Looking forward to the next video.

[@CRG]

I'm going to have to google that now as I did wonder what it says.

[@weepingscorpion8739]

@@CRG Well, from what I gathered it says something like: It's not pretty? (or isn't it pretty?) It isn't/no? Kiss my *rs*. I'm about 70% sure about the first two. And the final one was too similar to the Irish phrase "póg mo thóin" to be a coincidence.

[@RichardTroupe]

Great video and good to see another Amiga fan from Northern Ireland/Ireland! I have a TF1260 and use really low profile heat sinks and arctic thermal paste. Half of my 68060 chip is covered with heat sinks but I want to mount a small fan to blow some air across it. That will probably necessitate keeping the trapdoor off at all times for better air flow.

[@CRG]

Thanks, there are a few of us in or around Belfast and there was talk of trying to arrange a small user group meet somewhere local later in the year. If it does go ahead I'll put details of it on the channel. For the 1260 I think if I can at least cover the centre of the chip and get a small fan in there, that should be enough.

[@chriswareham]

Just started my Amiga odyssey - I was an ST owner back when these machines were new. I now have a refurbed A600, and I'm seriously impressed with how sophisticated the Amiga OS is compared to the ST's. Now looking forward to installing Lattice C and trying some C programming.

[@CRG]

Enjoy you're journey with the Amiga. If you write anything in C please let me know 👍

[@miked4377]

thats awesome that you got that tf1260!!! nice that you re did those chips....also amiga ireland looked like a blast!! great job all around crg!

[@CRG]

Amiga Ireland was awesome, highly recommended weekend of Amiga fun and yes its great to finally have a working TF1260!

[@deborahberi3249]

Nuice Video again! -Mark.

[@CRG]

Thanks, glad you enjoyed it.

[@Gunstarrhero1]

have you tried cutting or belt sanding the heatsink down some, find out where the clearance is on an angle maybe and just tapper it down a bit. id get a fan on that cpu as well even if they dont require them, as a rule of thumb, heatsink and fan on the cpu, keeps them nice :)

[@CRG]

That would be an option but I don't have a belt sander. I need to sort something though so leave it with me and we'll see what I can figure out.

[@DAVIDGREGORYKERR]

I hope that you get that TF1260 working in the end.

[@CRG]

Yep I got it working by the end of the video, once I got home and under some better light I noticed a few bridged pins. Reflowed that and away it went.

[@Breakfast_of_Champions]

A chunk of playdoh etc. on the CPU and push down the keyboard to shape it and get an idea, then take the cooler to the belt grinder. You can also try K5-Pro compound for a really thin and viscous pad replacement. The cold SMD joints should improve with a pre-heated board.

[@CRG]

Good idea, that will give me the profile then I can try and shape the heatsink to suit. The cold solder joint was just unfortunate but at least I got there in the end.

[@fu1r4]

26:50 Cut the heat sink like a wedge. You don't need a big heat sink. It is only 50mhz and not 50ghz 😄

[@CRG]

Its not the speed but the heat generated. Cutting the heatsink would be tricky I think but if I can find a means of doing it that will probably be the best option.

[@force4200]

Oh my god my friend you drive on the wrong side of the road ;) love the channel all from Sweden :)

[@CRG]

I've only tried driving on the right once, turning at junctions was fun. Straight into oncoming traffic when I wasn't thinking 😆

[@barnabas5688]

Hi Glen, I just have a smaller heatsink covering half of the 060 on mine (obviously the half furthest away from the front of the case) and then a fan off to one side providing some air flow. I have a rev 4 processor, at 50mhz it doesn't really get that hot anyway. The cooling is more important for the CPLDs in my experience.

[@CRG]

Thanks for the advice, I'm thinking of a wedge shaped heat sink although just need to find some way of making one. Belt sander would do it but don't have a belt sander. Running a demo for 20 minutes and it does it quite hot so needs something.

[@jzarfas]

(FAN)tastic 1260 vid Really enjoyed this thanks

[@LuisFCorreia]

Place half or three quarters of that cooler in contact with the CPU, it should do the trick

[@CRG]

Might cut it down to fit or might try another heatsink. There's been a few ideas in the comments here so plenty of options. Thanks for the advice 👍

[@peddersoldchap]

What if you file the edge of the heatsink closest to the front of the computer? Making it slim on that edge.

[@mart1nandersson]

I've had a 1260 with an LC 060 since they were made publicly available. I've placed different sizes of small heatsinks in a staggered way (a bit like a staircase) and it's been rock solid since day one (as it's only an LC and it doesn't really need the cooling). I initially thought about getting a heatsink similar to yours and then grinding it down but it seemed like way too much work.

[@CRG]

That might be an idea, would save a load of hassle trying to sand or grind down the one I have.

[@Gunstarrhero1]

even if you cant put a fan on it direct, some type of air flow would be best.

[@CRG]

I'll try to come up with a bracket to hold a small fan.

[@johnyk.4738]

Nice.

[@MrFixiit]

take a belt sander to the cpu cooler you only need to put a small gradient slope on the first 5 or 6 fins

[@CRG]

Just need to find a belt sander 🙂

[@Paul-qe8zv]

That's some nice soldering right there Glen, very nicely done. Can I ask what the gel type flux you use is, and where you buy it? Cheers

[@CRG]

Thanks, I use chipquik smd flux. Either the SMD491 or SMD291 stuff. I usually get it from CPC Farnell but if you're in a hurry Amazon also have it.

[@AnnatarTheMaia]

If we disregard the CPU versus FPGA and the pricing debate, is there any advantage to an accelerator like TF1260 over the Vampire?

[@CRG]

Disregarding CPU vs FPGA and price.... No, there is no advantage to the TF1260 over a Vampire. But with all cards on the table the only advantage I could give you is that the TF1260 is using a real period correct CPU. I can't really argue price either as the prices of a full 060 would probably put the TF1260 above the cost of the vampire. You may argue what's the point and all I can say to that is that for me anyway, an 060 is one things I've always wanted and purely as an accelerator the TF1260 does that job very well.

[@AnnatarTheMaia]

@@CRG that makes perfect sense to me: if you've always wanted an A1200 with a genuine MC68060, then things should be built together exactly as you want them, and that is final, because that is the criteria. I'm always looking to put all of my computers to some sort of practical use, and that requires processing power, and as far as I'm aware, the Vampire provides the most processing power on the Amiga.

[@CRG]

@@AnnatarTheMaia it's certainly one of the more powerful options but I also would consider the pistorm. The pistorm32 is now starting to filter out to people and will be a very fast option for the 1200. I'll hopefully be getting one at some point for testing 🙂

[@AnnatarTheMaia]

@@CRG what bugs me about the PiStorm is that it's an entire 64-bit quad core ARM processor emulating a 68060 with software emulation. Might as well run a pure ARM accelerator without the Motorola emulation performance penalty then (like Phase5 had the PPC Blizzard), but yeah that's a good suggestion if one is hunting for performance. Or maybe dedicate one core to emulating the Motorola and make the other three directly available as ARM cores to the system?

[@billcarson9565]

Great vid! Man I didn't realise there was an amiga event in Ireland!! I missed out this time!!

[@CRG]

Yeah Amiga Ireland has been going for a good few years now - amigausers.ie/ Maybe we'll see you next year.

[@billcarson9565]

@@CRG I've put it in my diary!

[@DAVIDGREGORYKERR]

It is weird that the XILINX chips don't say XILINX/AMD on them maybe they are old stock as they might be labeled in the future as AMD FPGA

[@ShieTar_]

If you add an thick enough thermal pad, won't the metal backing of the keyboard help to keep the CPU cool?

[@CRG]

Possibly although you'd need to be careful not to apply any pressure from the keyboard down onto the card. The 1200s edge connector can be a bit flakey at the best of times and putting any undue pressure on it might make it worse

Please make more videos you're awesome :)🤓

[@Gunstarrhero1]

what about a software driver to enable the fpu on board the 1200 with the lc?

[@CRG]

Can't be done I'm afraid, there is no option for a separate FPU with the 060 chip.

[@peddersoldchap]

Hi. Thanks for the video. What is the maximum clock rate of your scope and what is the clock rate that should be needed for that board?

[@CRG]

At the time the scope I had was only rated at 10mhz although anything over 1 or 2 and it really struggled. I have a newer handheld scope now thats rated for 120mhz although I've not pushed it anything like that yet. Scopes aren't a strong point of mine but as I understand you really need something rated twice of what you're looking to scope so for this card 200mhz plus. Take that with a grain of salt though...

[@peddersoldchap]

@@CRG So, 10mhz and 120mhz, those refer to the scopes' bandwith?

[@CRG]

Yes, that's the bandwidth.

[@peddersoldchap]

@@CRG Ta!

[@DAVIDGREGORYKERR]

Someone needs to create a custom waterblock to get the heat out of the CPU and CPLs.

[@CRG]

There is a custom cooler that sits between the chip and the socket which extends up beyond the cpu into the clear space in the case. I should probably get one so I can use this accelerator with confidence at the higher clock rates.

[@cherrymountains72]

Hi Glen, I just spend 15 minutes scrolling through all my comments on KZbin videos but i couldn’t find the video I responded to earlier but you had a video a while ago where you literally asked if it was possible to have ISOs on a storage device and mount them as if they actual DVD- or CD-ROM drives. And the answer I have for you is, yes, that is possible with an external SSD housing from IODD. It’s sold as a solution that autonomously encrypts/decrypts the data on the drive that you connect to it. But one of the other features it has, is the ability to mount any ISO files on that SSD as an additional device that you can boot from if you wish. And the encryption is not mandatory for this to work so don’t let that scare you off. I’ve got the IODD 2541 and I got it from Amazon for less than $100 (no SSD included of course). I hope this will make life a bit easier for you without having to burn ISOs to CDs or DVDs all the time for one-time use. Take care, Robert.

[@CRG]

Thanks Robert, can you reply with a link to the device? It might be blocked by KZbin but I'll keep an eye out for it and allow it.

[@cherrymountains72]

@@CRG Hi Glen, I replied but I don't know if you saw it.

[@YogSothoth1969]

Ah, too sad you can not use the keyboard bottom which is metal as a cooler itself, but if it sticks to the cpu, you could not easily remove the keyboard anymore, but the metal bottom would be a great cooler due to its huge size 😀

[@CRG]

I wonder if I could come up with a sprung bracket to hang down from the keyboard backing to press against the chip. Would just need to be careful to not put pressure on the edge connector 🤔

[@Plan-C]

Nice soldering skills! Looks great!

Thanks, so happy to finally have an 060 accelerator.

[@ninline2000]

Yes. I have a cyberstorm 060 sitting in my shed in a box. Time to head to ebay.

[@Darkstar2342]

yeah, a PiStorm emulating a 030 is still faster and costs about 1/10th of the 060 CPU alone...

Thanks for doing so, I couldn't see any issues when looking on the day either but once I got some decent lighting around me there were a few dry looking joints. Think I was just rushing to much down there or maybe it was all the pressure of the designer watching over me 🤣
