PC Engine Trash to Treasure (Pt1) - Restoring NEC's 8bit Wonder

[@RMCRetro]

We've got back to back Trash to Treasure episodes this week. If you are enjoying this series and want to support The Cave then head over to patreon.com/rmcretro where the next episode is now available on early access to all Official Cave Dwellers. Thank you for your support! Correction: The 2 chips on the bottom of the board are the VRAM not the 8k RAM Neil - RMC

[@MattyStoked]

I loved how candid this was! I would have re-shot or edited that part where the machine wasn't plugged in! I hugely appreciate your openness and honesty Neil, thank you for that.

[@digiowl9599]

Yep it was refreshingly candid. Love it when the humor isn't forced and the presenter does not seem to have had a few too many red bulls.

[@a_walk_down_memory_lane]

awesome. thank you. the Trash to Treasure series is one of my favourite series on youtube.

[@otopico]

Seeing you not having the video or power plugged in was the laugh I needed today. We have all been there, trouble shooting, only to find we failed the most basic step of plugging things in. As for games, if you can find it, Air Zonk is a fantastic side scrolling shooter.

[@WhatALoadOfTosca]

I'm a photographer and I don't know how many times I've left the lenscap on in front of customers lol.

[@CRG]

Nice fix and kudos to you for not editing out the failed switching on. Your face first had that have I broke it look then it dawned, twice. Made me chuckle. This is one of those system I keep looking at buying from those Japanese auction sites with the thinking that its small so postage shouldn't be that much. Looking forward to the next part.

[@danilko1]

@RetroManCave - Trash to treasure are my favorite videos. Thank you so much. Also I like the mail submission videos...

[@RMCRetro]

Thank you, I'm glad you're enjoying them

[@portnaluinge]

Love the PC Engine. It’s great to see these two alive and playable.

[@MegaHayes]

It's a shame when people don't have the skill to repair broken consoles and they're just scrapped, it's nice to see people like yourself spending time getting them into a working condition which any normal person would just think it to be beyond repair. So much respect! :)

[@thunderbird7780]

I could watch this all day.

[@MarkTheMorose]

Someone will do a 10 hour version, probably.

[@namakudamono]

Great episode Neil, thank you very much! I really enjoy the relaxing, friendly nature of your narration too - it’s like you’re explaining the processes right here, in my living room.

[@RMCRetro]

That's lovely to hear thank you I'm glad you enjoyed it

[@6581punk]

It's an 8-bit CPU but with great custom chips that NEC offered to Nintendo and they said no. Seems Nintendo is great at producing competition by rejecting help from others :)

[@6581punk]

Also I think the sound chip is really nice with its programmable waveforms.

[@PWNHUB]

The Nintendo market share isn't dwindling they don't need and have never needed to stray from their own path. Also, by todays standards they were right a cartridge would be way more ideal than any form of optical disc.

[@6581punk]

@@PWNHUB Sorry but you cannot dismiss the success of the Playstation. It was the turning point where Nintendo started to lose developer support. The fact that the Gamecube, Wii and Wii U used discs showed that the N64 using cartridges was a mistake. It meant a lack of a uniform experience across platforms with the N64 lacking cut scenes.

[@digiowl9599]

@@6581punk with the added irony that Nintendo could have offered a CDROM drive for the N64, as it had a bottom expansion port much like the SNES (that what became the Playstation was meant for). Closest was the 64DD floppy unit released in Japan.

[@arduinoguru7233]

​@@6581punk All mechanical drive added to any computer system should be labeled as ancient technology , Nintendo decision were right , but the solid state storage back than were too expensive to make

[@raggersragnarsson6255]

I miss the old green grid mat. The quality and work of this video is so apparent. Lovely.

[@creechrfeechr8094]

Sterling job restoring that! Very satisfying to see the result - a pristine white PC Engine fully working. Great video. 😊

[@dlinkster]

I always wanted one - well, the TurboGrafx 16. The CD-ROM was just so futuristic back then. This video brings me joy.

[@6581punk]

I bought the Turbografx 16 new in box recently. I remember C&VG covering the PC Engine and I saw screenshots of Out Run I think, was really jealous as the C64 and Amiga had terrible conversions (at least the C64 version was fast). But it talked of step down converters and NTSC to PAL devices required, so it wasn't going to happen. I was at school and importing games would have been expensive.

[@datriaxsondor590]

Nice work as usual. Replacing the voltage regulator is certain to be a huge improvement in terms of heat. Also a good call on replacing those caps, of course. Nicely done, and looks great. Look forward to part 2.

[@boatofcar3273]

Just starting this series Neil-I’ve always had an affinity for the PCE since I saw them on my first trip to Japan. Amazing how neat and compact the board is!

[@grumblekin]

PC Engine MASTER RACE! I love going to Tokyo and digging crates for PC Engine games.... Can’t wait for this plague to be done!

[@Th3OmegaPoint]

My favourite PC Engine games - R-Type, Splatterhouse, Street Fighter 2, Super Star Soldier, Ninja Warriors, Gradius, Devil Crash, Bomberman. So many great arcade conversions on this console!

[@IvanDSM]

Great video Neil, can't wait for Part 2! What you did with the connection between the main board and the HuCard reader looked really neat! :)

[@lordmuaddib]

my pc-engine duo-r says hello! enjoy this beautiful machine. there are lots of beautiful games on hucards and cdrom!

[@DRNicholasJones]

I really enjoy your videos your voice is so relaxing to listen too . Awesome to see these machines get restored back to glory .

[@tommylakindasorta3068]

My CD-ROM^2 Recommendations: - Star Parodier - Dracula X Rondo of Blood - there's a "heavy metal version" you can also find on the web - it's awesome. - Gate of Thunder - Lords of Thunder - Ys IV: Dawn of Ys English fan translation version (even the voices have been re-dubbed in English!) - Xak III English fan translation version

[@SonofSethoitae]

The Tengai Makyou games are pretty great too

[@allanalmeidapa]

Nice video. PC-Engine I always cherish are Bomberman-94 and Jackie Chan. Already waiting for the next episode. Greetings from Brazil.

[@The16BitterSNES]

Always lusted after a PC Engine (the original white model - the epitome of Japanese design). Managed to procure one last year fully modded, and am blown away by some of the quality arcade conversions and unique titles. A truly stunning machine for when it was released and what it could produce, a fine example of hardware and software coming together and being optimised for the job at hand. Then of course there is there is the foresight to push into the future with CD-ROM(ROM) technology!?! Amazing machine and great video Neil, thanks so much...keep going and stay safe.

[@lecompanero1124]

Wainting eagerly for episode 2. I love the PC engine and all their add-ons. Nice to see one in so good shape.

[@Tyresome]

Such good work man! It's amazing to play games and such on an awesome bit of rare tech. To know that you basically kept it going must be SO satisfying. SO much love!

[@corgibuttz2550]

I wish I could learn to work on electronics like this. It's so cool being able to identify things and fix stuff.

[@Septer_Sever]

Smart idea with the pin headers. I'm sure someone in the community will make a mass produced replacement for the ribbon cable at some point. I've heard of a lot of people breaking that cable when first opening the case. There is a jailbar fix as well if you replace a couple capacitors. Thanks for a great PC Engine video in 4k...we need more of those!

[@flekkzo]

Turns on. Nothing. One of us! One of us! One of us!

[@UltraHealthyVideoGameNerd]

This was amazing to see. I've only seen you do PC repairs and restorations until now, cool to see a console too. And I also had problems with this notorious model, ended up having to let it go and get a Duo-R

[@the_broly_arms]

I've watched every Trash to Treasure video you've put out, some numerous times, and I can't help it... every single time you say "IPA" I think, "Why would he clean it with beer?"... another awesome video on a far too-overlooked system!

[@regfenster]

Absolute beast of a gaming machine, I had one in 1988 or 89 from PC Engine Supplies based in London. £200 with P47 Thunderbolt. It was a great time to be a gamer back then as the PC Engine was a massive jump from the 8 bit home computers and left the 16 bit computers in the dust with its arcade quality visuals, sound was not all that to shout about though. Faulty Multitaps from memory could blow the internal fuse as happened to me a few times. You could argue that Sega's arcade ports where better on the PC Engine than the MegaDrive and nothing other than a NeoGeo AES could touch it for sprite handling duties. Shame it never had a proper launch into Europe other than the tasteless TG16. Happy memories indeed.

[@regfenster]

I'll have a dig later to see if I've still got the rare as hens teeth PC Engine to TG16 converter, it basically reroutes the pins on the Hu-card to suit and its a nice lurid pink as well. I've not laid eyes on it in decades but it could well be in the attic somewhere and if it turns up I'll post it your way as TG16 Hu-cards are considerably cheaper than the Japanese ones.

[@stephenbroderick7002]

Funny episode. Loved the power / video cable part. Laughed out loud. Thanks for making this.

[@johnknight9150]

Lovely looking main-board.That was a nice touch comparing the CPU speeds with the Commodore.

[@TimLeeSongs]

Another great video, I wish I had your repairing skills! Blazing Lazers, Bonk’s Adventure both great PC Engine games.

[@karlwalker1771]

Fantastic Channel sir watching this as Christmas has been Canceled by Boris and covid, this video has Lifted me :) Thank you and please continue.

[@GadgetUK164]

Great video! The RAM at the bottom is the VRAM, not the 8K of work RAM! The work RAM is on the slot PCB! Stay safe!!!

[@RMCRetro]

Ah excellent thank you for clearing that up sir!

[@GadgetUK164]

@@RMCRetro No worries! Nice to see the PC Engine getting some love on your channel - such a cool little box of magic =D

[@vix_in_japan]

Just catching up on some things I have missed recently Neil! The PC Engine sits very much alongside the SNES/SFC and PSX as one of my all time favourite consoles. Anything that helps restore these machines to their former beauty is to be applauded. Saw a CD-ROM2 system in Akihabara sans interface unit for only a couple of thousand yen, it was in bad condition and who knows whether it worked. Can't wait to get mine plugged in here once I get an RCA cable delivered, it's been nice to bring my PC Engine back home to Japan :)

[@MrVolksbeetle]

I love PC Engine and TG-16 stuff. That CD setup (briefcase, I think some folks call it) has been one of those things I've always wanted and just never got one because of fundage or lack of a place to put it. I'm really looking forward to this series.

[@retro_boy_advance]

I love how there's just a box of PC Engine parts, just waiting to be put together 🥰

[@Simon-ui6db]

After seeing jayztwocents solder an smt resistor, using your gun isnt a problem. But maybe louis rossman is having a rant :D

[@DJlegionuk]

Heat the board lol

[@silentfanatic]

Really good to see so much attention being given to the PCE. Should be great to see what you can do with the CD unit!

[@retro_reflections]

Such a beautiful machine, with some truly amazing titles, and a cracking vid too. Thanks very much, looking forward to pt.2! :)

[@shelby3822]

John Michael Godier's voice to fall asleep to and Neil's voice to wake up to over coffee, splendid indeed

[@randywatson8347]

It's a dream console. The PC-Engine has imho the best ports from Sega arcade games like Outrun and Afterburner 2. 😄 after soldering so much, everyone is getting mentally tired 18:30 nice job!

[@AmigosRetroGaming]

Great video Neil. I always learn a ton by watching these.

[@RetroSegaDev]

Thank you for giving me something different to watch everyday on my work break during these tough times :)

[@jevansturner]

Not specific to PC-Engine, but I have heard that a switching voltage regulator can cause jailbars or other strange effects with analog interference. I think it was Voultar who said it.

[@_yadokari]

First saw the PCE in a shop window on Tottenham Court Rd in London visiting my Dad's office during school holidays. Fast forward a few years and I had a newly released SNES, but I still remember seeing those big sprites and hearing "arcade" sounds coming out of such a small box for the first time.

[@spacedock873]

Love the double prat fall with plugging in the cables! 😂

[@vectrex28]

Here's a list of my personal favourites - you might've played some of these when I came over. Rondo of Blood, OutRun, Columns, Soldier Blade, Star Parodier, Gradius, Cyber Cross, Hany in the sky, Toilet Kids, Paranoia, the Bonk games, Galaga 88, Dragon Sabre, Dragon Spirit, Rainbow Islands, PC Denjin, and many others. Those are mostly HuCards too, there's a load of great CD games like the Spriggan games, Bonanza Bros, Gradius 2, Gate/Winds of Thunder, etc.

[@Ray2Jerry]

Can't get enough of these videos... a history lesson and invasive gadget surgery in every episode 😁

[@RMCRetro]

Thank you!

[@lancebukkake]

Oh my goodness - I had the PC Engine and the CD-ROM2 --- I Love it!!!! That game with the cartoonish characters is called "Wataru" It was one of PC Engine's earlier games. I also had that game :)

[@Micropops]

This will be an awesome Trash to Treasure series. I want the next part NOW!!! Lol! Keep up the great work! I love your show!

[@Colin_Ames]

I really enjoy your presentation style. Keep these great videos coming.

[@RMCRetro]

Thanks Colin

[@TranceTrousers]

I'd never heard of the PC Engine before, so I was hoping for a brief overview and history of it. Other than that another excellent episode. I particularly appreciated you not editing out forgetting to plug the power and video cables in - we've all done it before! Those 7805 replacements are great! I've fitted them in a few of my vintage computers.

[@RMCRetro]

I'd certainly like to go in depth with some history. There are a surprising number of models including handheld so I'd quite like to get a few more for the history deep dive. This would of course include the Laser Active which appeared on the channel

[@markhodgson2348]

Good to see a proper restoration video and not some fake all talk and no information, great

[@EugeneLychany]

Sweet episode man, I loved it! Can't wait for the part 2.

[@Waremonger]

Great video Neil. I can't wait to see the rest of the series.

[@TotalMoop]

Loved the outtakes staying in (in-takes? =P ) Great machines and really good for amateurs to cut their teeth on for mods. Nice pin pitches etc.. Interesting about the drop-in regulator replacement as well. Have not come across those. Thanks for the tip. You CAN modify the dock for RGB, though from memory, they recommend using one of the internal mods in it and creating a DIN output. MD2 Scart cable and din socket for cleaner presentation maybe.

[@HappyCodingZX]

two tips from me: 1) It's possible to remove the composite video out port and replace it with an RGB port wired to the correct points on the expansion port. Not sure but I believe you can use the same one that is found on the Master System which makes having the right cable easy. However this can get in the way of the CD-ROM unit, in which case it's worth considering adding a port to the expansion unit itself. You can actually do both. 2) Super Star Soldier.

[@fensoxx]

Splatterhouse was a great game i used to have for turbografx-16. English language. Great video thank you!

[@frostwise87]

Very impressed, brilliant restoration :)

[@RMCRetro]

Thank you!

[@infopackrat]

Here in Canada we were always jealous of you guys in Europe with SCART. That should have become an international standard. I'd use it today for retro stuff if they put it in your typical TV.

[@y-cyastorr8459]

Uh. This Console - was the first CD based Console and my favourite for a long time. True 8/16bit power. I had the grey CoreGrafx (same as the white PC-Engine) with the white Interface and CD-Rom. That console system was the cooles looking - even today!

[@ST2008X]

Space Harrier, Afterburner II, Galaga 88......My only 3 PC Engine games.....These are great games...

[@MisterRorschach90]

It’s so cool that the logic board is about the same size as an itx or stx motherboard. That means you could transplant it inside of a modern usff gaming case if you wanted to be different.

[@Laserdreamz]

Tbf the PC Engine composite is lovely. Nice vid btw always good seeing PCE content.

[@monktoncrew]

The best little 8-bit console! Gameswise, I'd go with Gradius, Salamander, R-Type, Star Soldier series etc for shmups, but my all time favourite (and most expensive HuCard) is Parasol Stars. Fantastic Bubble Bobble sequel. Never got an arcade release!

[@GerardKean]

My favourite type of video. Keep 'em coming

[@CLS2086]

In FRance, we were a bit more lucky, They was SoDiPeng (société d'importation des PcEngine) that sold officially converted Japaneses NTSC/60 PcEngine/CoreGraphX/SuperGraphX units to RGB/60 (as no one realeased any more Secam systems since mid 80's). So a very "modern" TV that handle RGB in 50/60 Hz was required instead of a much pricer compatible NTSC/60 TV set.

[@abc-ni9uw]

When he said 'it's just age' that threw back a little 😔

[@GreatOne0815]

I never had one but for me the PC Engine was and maybe is the best looking console ever.

[@sjfvideo9508]

You do some cool stuff on this channel but this episode is exceptionally cool. Well done!

[@LeeTennant90]

Great video been waiting for this. I have over the past 2 years built up my pce. And have a working pce, rgb modded interface unit. Everdrive. But the bit I want to get working is my CD drive. So looking forward to part 2. Had my drive recapped and middle gear changed. But still needs a lens replacement 😢 Even managed to get a cheap arcade card Pro. So they are out there if you take your time. Loads of great games. And the best version of street fighter 2. But okay with a 6 button pad or stick.

[@cheater00]

Hey Neil, so I was wondering, what is the ripple like on the new voltage regulator compared to the linear one? How does the video output compare, when looked at on the scope? Thanks!

[@RMCRetro]

That's not something I've checked Cheater as it looked fine in action so I had no reason to investigate further. Sorry matey

[@thingnumbertwo2]

Awesome video. The PC Engine is a fantastic system; it's a shame it never really took off in the west because we missed out on a lot of great games. My recommendations for Japanese but English-friendly CD games include Ginga Fukei Densetsu: Sapphire, Akumajou Dracula X: Chi no Rondo and Seirei Senshi Spriggan, as well as the western versions of Last Alert and Gate of Thunder.

[@squeeeb]

Great stuff! Love the header pin mod.

[@leelangley3038]

This is pure retro porn, great work. I still go back and watch the Amiga 509 trash to treasure, never gets old.

very chilled and informative/interesting video :) i will be looking forward to the next part :D

[@johnrkostelnik9039]

I enjoyed watching this presentation very much, thank you. The PC-E / TG16's were really ahead of their time compared to the Sega Master Sys. and Famicon / NES systems of the day. I'm looking forward to the follow up :_)

[@JomasterTheSecond]

Man, seeing that Wataru cartridge just makes me happy and I don't know why. XP

[@faselei7774]

Great work as always! ..just make sure you find that copy of chase hq! it's a great conversion. Maybe give nectaris/military madness a go if you like the advance wars/shining force style games. There's a cd version of nectaris which is playable despite being a mix if Japanese/English. Anyway looking forward to the rest of the series!

[@vix_in_japan]

Also one tip if you need to open a PC Engine's and don't have the correct screwdriver, take an old biro (Bic ones are pefect for this), and take the ink and nib out, and then gently warm the nib end of the biro shaft, and then press against the screw until the plastic solidifies. Voila, instant cheap screwdriver for opening your PC Engine if you ever need to :)

[@jonatana.4540]

Such a beautiful tiny machine, but still able to pump out some quite impressive visuals. And the game library is just massive. Play some Super Star Soldier, Gomola Speed, Dungeon Explorer, Bonk, R-Type, Parodius Da!, Valkyrie no Densetsu, Atomic Robo-Kid, Air Zonk, Download, Ninja Warriors, Out Run, Bomberman '94, 1943 Kai, Dragon Saber, Street Fighter II CE (very impressive version, but kind of needs the six-button pad)... the list goes on and on and on. I'll save my Super CD-ROM recommendations for the next episode :)

[@BeyondTheScanlines]

Nice job with the restoration! Though I kind of prefer the grey of the CoreGrafx units, the original PC Engine is so striking in its own way. As for game recommendations - the first port of call is with the shmups, there are an amazing amount of them, on both HuCard and CD. HuCard wise my picks would be Galaga 88, Super Star Soldier, Gunhed/Blazing Lasers, Soldier Blade, Xevious plus Gradius & Salamander. Some non shmup gems are Victory Run, Out Run, Devil's Crush. I'm sure there's plenty I've missed too. As for CD games, on the shmup side Gradius II, Gate of Thunder and Lord of Thunder are all worth digging. Ys Book I & II is great (though hopefully there's a way to get the US version running on a Japanese system for obvious reasons). And I did chuckle a bit when you were getting it all going, because we've all been down there before.

[@discovermetaldetecting]

I love these Trash to Treasures! I wasn’t aware of this console so it was interesting. I would love to be as skilled as you Neil....I’ll stick to construction however! 👍🏻

[@mikgus]

My first successful repair job was changing the 7805 in a famicom (multiple times). Ended up with it mounted on the outside with a huge heatsink.

[@El_Guapo74]

Cave's attention to detail is pretty impressive.

[@jeremygregorio7472]

I love how futuristic the PC Engine CD looked 😛

[@RetroTuna]

Nice video love the Pc Engine and fixed a fair few of them myself, an answer to you question yes you can mod the interface unit for rgb but if you do take the audio from the board at the back of the phono connectors as if you use the digital audio you get noisy interference and you will have fun getting it apart.

[@Asriazh]

Near the end of the video, when You lifted up the bag with the cd-rom² in, a screw fell out and you kicked it all around the table with Your sleeves. I hope that poor screw is ok *lol*. Apart from that, yay! One of my favorite consoles. Isn't it cool and sleek looking? And it had CD-rom support before it was cool! I really like that little thing ^_^ That voltage regulator swapout is a great idea. I might do that to my PC-Engine as well. I bet it would like getting less hot. Thanks for the video!

[@EsotericArctos]

Great restoration. If all different outputs are on the connector pins, you should be able to just find the same pins the cable uses in the expansion port. I am not very familiar with this device. I look forward to seeing more. It looks quite interesting.

[@DowhatyouWantRokim]

the 7805 you replace for OKI-78SR-5/1.5-W36HE-C would you recommend it for the Sega mega drive and Snes they use the same
