Did I get ripped off with this PC barn find ?

[@LGRBlerbs]

Thankfully the COASt module was reverse engineered and reproductions are available. I made a video about it titled "M919 Fake Cache and Reproduction L2 COASt Modules." Sadly I haven't seen them on eBay in a while, though I believe it was an open source design so hopefully someone else makes and sells them again. More info is on Vogons in a thread titled "Lets make new M919 Cache sticks"

[@CosmoRiderDE]

saw your video back then. I kind of scan youtube for videos about this particular board hehe.

[@dallesamllhals9161]

If I could just find/get one for a Tulip* Socket 3 😞 *Yup! Dutch they AR#%were.

[@RetroSpector78]

Most of that stuff seems to be in the US so shipping to Europe is always a pain unfortunately. Might be a nice pcb project. Still glad to have this board. Looking forward to exploring it some more. The desktop case from your video also resembled the one I have with this pc.

[@xero110]

When I watched that part I was very surprised that no one had made one. Good to know they are available.

[@BilisNegra]

Clint here commenting from the Blerbs account? I wish that meant that channel is going to be a bit more active again, I appreciate those laid back videos.

[@CosmoRiderDE]

The infamous famous PCChips M919! one of my fav boards because when they are setup properly and got their L2 Cache module they are superb performers.... that when you manage to find this rare proprietary cache module.The M919 got an undocumented 60mhz bus clock setting too afaik, when you want to do a decent Am586 overclock to 180mhz at 4volt. But anyways, this board and also previous models (i.e M912 VLB) with fake cache onboard are legendary history.

Infamous garbage from hell

[@CosmoRiderDE]

@ Well, there were plenty things that PCChips has done in the past that were very questionable and somehow a scam, but i must say, i own several boards of them, different platforms, cannot complain about the quality they delivered. At least the 386 to Pentium II era. The boards i have, are great performers, and the M577 has an outstanding quality in my eyes.

[@benrogers84]

@@CosmoRiderDEhad a pc chips m741lmrt slot 1 and socket 370 weird mobo ! Had 8MB SiS620 / 630 vga. Also owned a m810lmr 7.1 which ran SiS 730 vga onboard very bad performance but very cheap board. Was very picky with memory.

[@7828191]

My first PC (a new 486 DX2-66 VLB) had that same 3 button mouse, but without the printing on top, also rebulding that one now and updating it abit (Pentium, Socket 7), and that exact same CD-ROM is what i have chosen for the build :))

[@RacerX-]

Wow such a cool spread of time periods in one motherboard... Nice, looking forward to part 2. Keep up the good work.

[@smakfu1375]

Okay... that's a new one for me: I didn't know some motherboard vendors were slapping fake sram cache back in the day. That's nuts, but if buying a board at a computer show, you'd look at that board and think it was cache equipped. I'd have been pretty angry to get home, boot it up, and find out I didn't have any L2 cache.

[@hi-friaudioman]

Yeah it has fake cache modules. You can tell because the chips are larger than the real ones and the traces lead nowhere. I've encountered a couple of these boards and it's always a trip. Lol

[@CptJistuce]

Oh, the BIOS is hacked so it lies about how much cache you have. You won't find out you didn't have cache just by booting it.

[@smakfu1375]

@@CptJistuce Wow, thats even sleazier… but I will give them credit for thoroughness.

[@catriona_drummond]

Configurations like that usually happend because somebody upgraded a machine but eventually got a new PC. So they would plunder the best parts, like maybe an early 3D graphics card and put it in their new Pentium II, which had onboard sound so they left the sound blaster behind. Then they dug out the old original VGA card, put it back in to have a working system and gave it to their little brother.

[@SandsOfArrakis]

That sounds like a good explanation. I've certainly passed on a bunch of hand-me-downs over the years.

[@rodhester2166]

Thanks, looking forward to the comparison video.

[@stevec00ps]

What an interesting machine - such wildly different age parts!

[@Madness832]

As soon you it was determined that you had a PCChips motherboard, I immediately thought of fake cache!

[@Inject0r]

I’ve come to love the PCchips motherboards, due to their quirks. It’s quite badass that they kind of got away with the cache issues for quite some time. :p

[@jasmijndekkers]

Nice computer system. Nice to see you work on it. Enjoy it. Greetings from Steven from the Netherlands

[@dykodesigns]

That videocard in combination with a 100 mHz cpu is such an odd combination. That motherboard/cpu combo could happily run Duke 3D if it was paired with a nice VESA compliant SVGA card. I guess the original owner probably didn’t care too much about graphics performance as that card is more fitting of a 286/386 system. I tried to run Duke 3D on a 33 mHz 486 back in the day and it could barely run at a playable speed (kids these days are a bit spoiled with framerates, back then you where happy that you could run the game at all and play it) but at least I had a Paradise SVGA card because my dad wanted high resolutions when he originally bought the computer in late 1992.

[@SandsOfArrakis]

My first PC was a Cyrix 486 DX2 80 MHz, 8 mb of RAM and a 1 mb SVGA card. And it struggled with Duke3D. After buying a new PC (Pentium 133) Duke3D started flying. How much difference a new computer made back then.

[@bstar777777]

It's an odd choice because the machine originally booted directly to Windows. Screen redrawing would have been really sluggish vs a budget pci video card.

[@sneekeruk]

fRom memory I bought one of these motherboards off a friend as It enabled me to go pci cheaply from my vlb system, so it started vlb and I bought pci cards. The faking of the cache worked fine with a dx4/100 but mine had previously gained a cyrix 5x86/100 and when that was installed it wouldnt fake the cache properly and would only boot if the external cache was disabled in the bios.

[@BilisNegra]

I'm really looking forward for the next video for this system. This kind of hardware ticks all my boxes!

[@thetaleteller4692]

I like how the silkmask on the boards where white with reasonable text size. Today you get dark-grey on dark-something with 1mm font size and some puny flyer which does not even explain the pinheaders.

[@collectingretrotech]

nearly 30 years later i think its kind of cool to own one of these boards with fake caches in any vintage collection

[@upgrade1373]

Seems to be in pretty decent shape for being found in a barn with or without fake chips

[@IkarusKommt]

It's Europe. A mild, dry climate. Good for storage.

[@CaptainDangeax]

I like vidéos about those old PC hardware. My first PC was built over a Hippo VL+ motherboard, no external cache. Now I prefer to play with older hardware like C128 or Amiga500

[@krz8888888]

well equipped motherboard i/o wise, wish I had one

[@kokodin5895]

very similar to my old mobo, i had a cash stick though and i remember umc chipset, 4 simms , white ide connectors and similar number of expansion slots, even the bios is the same i had 2 8mb sticks of memory and 133mhz amd cpu and i didn't know a thing about computers :]

[@IgnatSolovey]

PCchips was a cuss word in the second half of the 90s. I remember refusing every third order at a certain time, when somebody asked me to assemble a PC (as a teen and some years later I made my pocket money with that) with particular CPU/RAM specs and an inadequate budget, because it meant a PCchips or a ZIDA/Tomato board, and I was just a boy, not a retailer with a warranty department to mess with those highly integrated and similarly buggy wonders of technology. So I lost customers who would be a royal pain, opting to take fewer orders but from people who were willing to pay some extra for quality (that at those times meant Gigabyte, Abit and Chaintech mostly, because Asus and consumer-grade Supermicro, Intel, or Tyan boards were sort of for VIPs with wild cash). The irony was that at some moment I ended up with a PCchips board myself because it was a freebie that was burn-in tested and proven as working. At the first opportunity I switched to an original Intel board. But never I seen as many BSODs of Windows NT as with that abomination.

[@airfixer9461]

Great part one, looking forward to part two of the video 🙂

[@justsumguy2u]

You can tell they really got their use out of this machine; they wore out the first hard drive, and then wore out the second

[@georgez8859]

Very nice Find. you gotta love those fake Cache chips on PC chips motherboards.Thanks for the Video.

[@peterdevreter]

Nice board! I had something like this back in the day. I was too poor for a real pentium 60 (dodged the bullet there 😂) and bought a and 5x86-133 instead. Doom and quake ran pretty good!

[@maxtornogood]

The infamous PCCheaps board!

[@RetroTechChris]

Haha. Okay, so I am halfway through the vid. Thought "what a neat bridge PC." Then you said PC Chips, and then Write Back. I knew what was next!!

[@Otakunopodcast]

Haha, the moment I heard you say that the mobo was PC Chips, I groaned, I had a feeling of what was coming next. Sure enough, seeing those obviously fake looking "cache chips" confirmed it. I never knew about this controversy back in the day, even though I am almost positive I have owned at least two or three motherboards with fake cache like this back then. I was the kind of person looking to maximize performance while on a budget, so if I saw something advertised as having fast cache at a reasonable price, I probably would have bought it. Of course back in the day we didn't have widely available fast internet, social media, etc. so information didn't spread as rapidly, so I'm not surprised that this controversy remained relatively obscure until nowadays. Some of the "fake chips" boards actually do have properly laid out traces, so you could desolder the fake chips and install real cache chips in their place. But you would usually have to also flash a new hacked BIOS on the board, because the BIOS on these boards was hacked to secretly disable cache while still displaying the "xxx KB CACHE PRESENT" message even though no cache was present. A while back the KZbinr CRG did this (retrofitted real cache on a fake cache board) on one of his videos.

[@darioperezdario2638]

Very interesting computer. It reminds me of when I read a magazine where they mentioned "Overdrive" processors, low-cost alternatives to the first Pentiums. And this AMD AM 486DX4 was among them. I would love for you to install a CF disk using an adapter and try to install Windows 3.11 on it.

[@stphinkle]

Those are very common from back in the day. Looks like early to mid-1990s.

Ah yes, the "faith cache" 😁 ya just gotta believe!

Ahhh, the legendary PCChips fake cache boards... such a wonderfully ridiculous piece of computer history. I've got one floating around that I've kept precisely because it is so dang ridiculous.

[@christopherdecorte1599]

Has any tried jumping the traces from the fake cache to the pins from the proprietary cache slot with real chips I think it would work fine if can find the pinouts. Especially since the traces has decent looking vias

[@nickwallette6201]

That’s a dead end. The traces are just meant to look impressive. There is no telling what those chips REALLY are, if there’s anything in them at all. And basically zero chance that the traces that ARE there, would go where they needed to go, if you could find SRAM in that package. You would almost certainly have to break all the trace connections, and add budge wires for all the relevant pins. At that point, you’re way better off spinning a new PCB to go in the COASt slot.

[@JayJay-88]

Great fun as always ☺ About the beautiful "Syntha" computer shown at the end, do you know who manufactured those cases? My first computer had one just like it but without the Mhz display. AMD 386 DX40. Loved that case and its fancy door. 😆

I would run Spinrite on this drive to see what you can recover! It is the MUST tool for any vintage computer user!

[@zoomosis]

I've often wondered if Spinrite can revive a half-dead disk like this one or if it's just snake oil.

[@jasonhaman4670]

It depends on what the problem is. Reading the info on HDD Regenerator, which is kind of similar to Spinrite, a lot of drive defects are weakened magnetization on the platters. HDD Regenerator does a low-level read, as repetitively as needed to read the bit, then re-writes it, refreshing the contents of all 'bad' sectors. If there's actual physical media damage, that can't be repaired. But based on how much success I've had recovering drives with both utilities, at least with then-current drives 15ish years ago, the majority of drive defects do seem to be magnetic rather than physical, and repairable/recoverable with those utilities. DEFINITELY worth a try with this drive. Actually, HDD Regenerator/Spinrite should be tried BEFORE chkdsk/scandisk, as once those mark a sector as bad, it would be difficult to un-mark them as bad/restore the data to readability in the FAT.
