Today I was testing all of my SCSI equipment I've bought during the last months :) I missed the SCSI completely, until I became the real system administrator in late 2000-s, but that was a time of SAS, nothing interesting. So I wanted to add a touch of SCSI to some of my builds. 1. For 486 I've got …

@jheronimus, yeah, it seems Gateway MBDPCI016AAWW based on Zappa board without MB cache and PS/2 instead of DIN. Or probably known under name Aladdin. Thanks. @Babasha will try but seems like it's dead. I'm going to order Socket 7 mobo and then decide whether I want to stay on pure Pentim or Pentium …

Tnank you! Battery didn't help. BIOS cannot be fixed, the chip is not extractable. I'll check the capacitor but it seems like it would be cheaper to get a new Socket 5 / Socket 7 motherboard for my Pentium build 🙁

Dornkaat, I added the images. jheronimus, I tried booting with ISA without success. On the other hand, if the additional connector is just an optional addition, there should be 3.3V on PCI slot got from some other source and there is not. Plus this can be OEM board so the additional connector may be …

I have an intel Socket 5 motherboard with Pentium 100 CPU. I don't know an exact model, as Intel did not provide it on their mobos, there is not even 'Intel' trademark on it. But it looks very similar to Endeavour and similar mobos of that time, with that typical intel long DIP switch for settings, …

If it's about Keystron that looks like modern replacement. That's good it's possible to find such a thing, but for my 486 I am completely satisfied with 8MB. I wanted 16MB for my late 486DX4-100 so badly but now I just try to recreate something balanced. Don't see much sense in 32MB DX2-66, there is …

Is it possible that 4 of the simm slots are for FPM simms ? and the other 4 are for EDO ? I have no idea if you can run both types together. Doubt there were 30 pin EDO modules. At least m/b manual doesn't mention that. Anyway, all modules I have are FPM ones, I checked. Also, all modules have …

I've just had a strange RAM behavior on 486 VLB motherboard. It's ECS UM486V rev. 2.0 motherboard that has 8 30-pin connectors for memory. Specially for that case I bought 8 sticks of 1MB SIMM30. 4MB SIMMs are hard to find and expensive. All of these RAM modules have 3 ICs on them but from different …

wiretap, thank you. We have something similar, but unluckily no RAL color. Need to try several.

I've bought a 386 motherboard (with soldered Am386Dx-40) as 'non-working' just for the cache ICs and FPU on it. It had a leaked battery (that I removed for sure) but the harm it caused was insignificant - just a sport or two without corrosion, just removable surface leakage. So I gave it a try. It …

It is nothing special. Just a flat gray primer/paint all-in-one, with anti-rust properties. The old computer cases usually didn't use aluminum since it was far more expensive than sheet metal.. Unless you had a really high end case of course. @wiretap, could you please provide an example? I don't …

Does anybody know is there any paint on PSU and internal parts of the chassis originally? That matte gray aluminum surface, what color do they use for it? During case/PSU restorations people usually paint it either with black paint (that looks good but is not original) or with somewhat silvery color …

I've also got this problem :) My first PC was Am486 DX4-100, that was intermediate 486-Pentium solution. Despite being nostalgic I wanted to play with Intel in my retro builds (my main home computer always was the AMD since 1997 till today). So I planned to play enough with VLB that I've never …

Once again, what do you mean by "works"? Here is the table of the DOS games with known 'attitude' to the videocards. https://gona.mactar.hu/DOS_TESTS/ Obviously, Matrox is not THE BEST choice if you need the videocard that supports (almost) ALL of the DOS games. This requires strict following of all …

What's the good complement for PAS 16 to get maximum of compatibility? I have Vibra 16c but it has problems with SB Pro (mono only) and also lacks IDE port (not soldered) so I'm thinking about YMF-719. It has one additional IDE that will be useful, stereo SB Pro compatibility and proper MPU-401. Any …

@Shreddoc - C&C is good and there are three options for you now. Original C&C/RedAlert in VGA resolution, C&C Gold in 640x480 and the newest rework. I liked the Gold version much more as 320x200 is somewhat less playable. Starcraft is amazing, both first and second games (and even Reforged one). It …
