I found this board in a generic turbo xt case i just got. Is this a combined 386 486 board? Anyone recognize this?

Is there such a thing as a 386/486 board?

Yes. They are not common, but not rare either. They don't (as far as I can tell) support anything above 486DX2

Looks like OPTI Local Bus (hint: AMI "ISA" BIOS). Do not put EISA cards into it.
And it has no L2 cache.

A DRAM tester, and a very good at it. The cool thing is that it has a NEC v20 inside ....

Sim_Check_02.jpg
"don't turn it on, take it a part"..... Had to, 110v tranny had to be replaced.

Also a ultra rare diagnostics card for Schneider Euro-PC .... maybe 2 of them of different test types :

A PSU for Schneider EuroPC .... in good condition:

Viva,

Chamo-me Luís Rodrigues, sou de Santarém e tenho um EuroPC avariado que não consigo dar com a avaria.
Já perdi imenso tempo com o mesmo e estou quase a desistir de repará-lo.

Pelo que vejo no seu post tem duas placas de diagnóstico para o Euro PC .
Está interessado em vender alguma ou eventualmente alugar uma delas para eu tentar uma ultima tentativa de raparo do mesmo.?

o meu email é lusimcrodrigues@hotmail.com

Com os melhores cumprimentos,
Luís Rodrigues

Hello Luís, I'm going to respond in English so I don't break the rules.

Unfortunately I'm not interested in selling, and I doubt the utility of the card because i think they are intended to test the first variant. The diagnostic cards assumes that the machine maintains a limited capability (that's why they have roms), similarly to the ibm Supersoft/Landmark Diagnostic ROM's (http://www.minuszerodegrees.net/supersoft_lan … dmark%20ROM.htm). In my 2 machines the damage was so sever that they fail to execute.

The second iteration of the euro PC has a lot of differences that may play against :

1 Memory "encoding" (not really but different glued logic) of 640k
2 The "big jim" (cpld of sorts) that controls setup of video modes,joystick/mouse port, and select lines
3 U7 (also cpld of sorts), that I don't have a clue of the function
4 keyboard/reset controller (68705 masked microcontroller in my euro-PC)
5 The Euro-pcII has a strange dc-dc converter onboard

And the most important reason is that I'm still working on a new MB for the Euro-PC (not the II). I will have some goodies coming in the next month that may push to the conclusion of the project. I will create a new topic as soon as I put my Frankenstein of a programmer working correctly to burn the 68705-u3.

Be patient, don't give up! Just to make a new MB I had to check every single via and pad multiple times, and still managed to make some mistakes , but then again, that's how you learn.

Hello Xicor.

On my damaged EuroPC II i have a reset signal out of FE2010A with ony miliseconds of hi state compared with my working EuroPC that guives 1,6 seconds reset time.
Have you any clue?

note : The actual FE2010 was replaced.

Best regards
Luis Rodrigues

I got this last week, sorting through it - the top right is actually a 486 DX2/66 - I had to coax it back to life.

All the other stuff works, some will need recaps but mostly in good condition. I basically bought the lot for the blue case and the 486 (which I thought was a Pentium 75 -166 machine), the rest will get gradually repaired and end up on eBay I bet.

https://maxsold.maxsold.com/auction/25111/ite … tm_medium=email

I've already got a build for that blue case - a first gen i7 with some kind of 1Gb video card. I might make a video out of it time permitting.

Two nice parcels this weekend:

Yep, yet another MSI-6168 v2 i440BX board with onboard Voodoo 3. I already have three others, but first one has dead SGRAM artefacting all over the place, second is rock-solid, but refuses to boot with Coppermine, let alone Tualatin. Third loves Coppermine but isn't stable with Tualatin via Upgradeware Slot-T adapter. Was actually happy with that, but spotted this fourth one for a very low price, so hell, why not 😉

Needs re-capping, but that's normal for these things.

And then there's this:

Socket 287 goodness. Intend to run a special flavour of WinNT on this, once I've figured out how to get rid of the MILO bootloader.

I was wondering the same, but I suspect some kind of VAX or Alpha board, although I know very little about anything that's not x86

Nice one. I'd say DEC Alpha 21066. It is quite cool motherboard. Note there is no chipset. Just Intel SIO. The PCI controller and northbridge is in the CPU.

Dead right. It's a DEC "noname" AXPpci33 board with 166MHz Alpha 21066 on it. Pretty low-end as Alphas go, both in terms of clock speed and system bus ('only' 64b wide), but in context of when it was released still a monster: the fastest Pentium at the time of the release of the 21066 166MHz was 66MHz, although by the time this board was released you could get a P100. Of course, IPC of a pure RISC design was lower, but clock-for-clock a Pentium was around 1.5x faster, so this thing was still faster than the fastest Pentium in its day., particularly in FPU-heavy applications.

I've actually been looking for an Alpha 21164PC CPU, as I have a nice ATX board for that with no CPU, but they appear rarer than hen's teeth (the last one on CPUworld of course was sold a week before I started looking almost 2 years ago :') ), so this was plan B.

20-odd years ago I ran Linux on some Alphas, but for lack of a decent purpose (they were outdated by then already) that was really not worth the effort. Now I want to run WinNT for Alpha (or if I find that 21164PC Win2k RC2, the last Windows-for-Alpha version) and see how usable the x86 emulation/translation is. Supposedly around the time this came out, an Alpha doing transcoding was actually the fastest CPU to run x86 code on. If so the obvious question is: will it run Crysis Quake 😉

Fun fact: Alphas are the reason Windows insists (to this day) that memory mappings be aligned to 64KB boundaries instead of 4KB, natural page size of x86 (and nearly every other architecture) and thus infuriating every emulator developer working on systems that make use of a MMU.

Speech Design Audiocard 300E vintage speech recognition card for PC - ISA

Speech recognition? What application would it be used for?

Well, I guess it would be used for some early version of a phone 'menu'/pre-recorded answers etc, when you call a a company you could speak words instead of pressing a button, to get to a certain online answer menu/options etc perhaps. Real handy for us who would only have an antiquated rotary dial phone at that time... (from the 1970's and early 80's). Think of all those clue/hint lines for early PC games for instance. Or perhaps banking etc.

Could also be for disabled people.
Also good luck getting drivers for that thing 🙁

Hi luismcr.... Check your email.

Today i received a new member for my midi "tower of power", a Korg NX5R (@110€ including shipping), that has seen a lot of action in the "battlefield", but nevertheless fully functional.

It was a bit dirty, some marks and scratches, a bit of rust on the edges, all expected ..... But internally is beautifully preserved.

I was fearing that past owner had scavenged the Yamaha module, it turned out to be where it should.

Bought the single CPU processor card for the proliant 1500 just in case.

Cheers,

That is a great price! I paid about that amount for just the DB51XG board.

So far, november was "CPU month" for me, and I'm quite happy.
Last week I turned 40, so I kind of gifted myself with these chips:

Intel DX4ODP75 overdrive SZ956
Intel DX4ODPR100 overdrive SZ959
Intel Pentium 66 SX950
Today a coworker of mine, knowing that I have this "crazy hobby" of collecting old CPU's, gave me these :

Intel A80386DX-25 SX218
IIT 3C87-33 co-processor
Intel A82385-25 SZ144 cache controller chip
Intel A80486D X4100 SK096
Intel Mobile Pentium III 500 MHz SL3DW
Intel Mobile Pentium III 1 GHz SL53S - the fastest mobile Cu-mine CPU as far as I know
Intel Pentium M 735 @1.7 GHZ SL7EP
Intel Mobile Core 2 Duo T7500 @2.2 GHz SLAF8
Intel Celeton D 320 @2.4 GHz SL87J
Intel Mobile Pentium 4 532 @3.06 GHz

I was wondering if I could get a socket 478 desktop mainboard and test the 487 pin CPUs, to see if they work...
So far, so good...

Thanks!

Not really anything special and condition of some cards is so-so but will come in handy for building some rigs for sale... I'm mostly interested in the MiroMedia Surround card - addon DSP for regular sound cards. It implements Dolby Surround for 2 or 2+1 speaker setup so I hope for it being a bit more than just another 'spatializer' which was a common thing on sound cards back then... Also the Digitan DSAC-300 sound card seems a bit uncommon. Havn't seen one before...

Thanks to your work @ www.wavetable.nl, we all can choose the modules and sound cards that for each of us are more appealing , and to me it was an invaluable help to make my mind on which ones to pick... So, my hat's off to you Sir !!
Also, I feel sorry for the NX5R that roams the earth without its companion DB51XG....
