Looks like it's going to be a beast! 😁

You also have a VLB topic, what do your 2 cases look like I wonder? 😀

Me too 🙁
I found a aweful basic AT case for now.
I'm looking for two good cases with frequency LCD and turbo button, but it's gonna be long to find ...

I spent 1 year gathering all you see in my topics 😀

If you did it without overpaying, then I'd say "Well done!" 😁

Well, some of it is overpaid, some other was quite OK (bunch of stuffs for nothing).
I guess it averages at an okayish price, but I could have done much better with more patience...

Here is the full list of what I got during that year : http://imageshack.us/g/1/10031227/

If you stick to what I'll use for those two 486s, it's much less than total of course. For example, the NIB POD83 was not needed, etc ...

Funnily, the most expensive is the "little" things, like SCSI 50-->68 adapters, etc...

I think It would be around 150€ per 486.

Dang, still quite a bit of money, but not impossible. But otoh, a new "new" computer usually costs much more then just €150.

And you have the same Socket 4 mobo that I have! 😁

I hope you find the cases soon 😉

I'm on it 😀

Ok, we could spend a bit of time this saturday on the PCI 486.
We passed the 2940U2W barrier.
We tried the card on all PCI ports, none worked.
We tried with a different HD, did not work.
So we tried a 2940AU, worked on first try. So we cancelled the 2940U2W plan, it's gonna be 2940AU.

We also cancelled the Trio64V2/DX plan, because the card was giving a grey backgound instead of black, so it must have gone old badly. We put a Trio64 V+ instead.

We finaly managed to boot the computer with all drives recognized. But we blocked just after.
First, it's annoying to get the PC to boot on the FDD, since the SCSI takes the lead. We have to press F12 at the right time.
Second, my MS-DOS set is not bootable ... Dell special edition it seems.
third, none of the boot disks we made worked, it always end up with a bad sector/IO error stuff. We tried 2 floppy drives, 2 floppy wired, several floppy disks, we check the floppies on another computer (they were reported clean)

I'm beginning to think the floppy ctrl on the motherboard is faulty ...
Can it be turned off and replaced by an ISA one ?
What motherboard would be a good replacement ? I have an American Megatrend PCI Voyager II, is it any good for the ADZ 5x86 ?

What's the procedure to install MSDOS ? the OS askes for SCSI driver at some point ? Cause the boot disks didn't link any drive on C:

On the good sides : we received the two XR385, one for the PCI, one for the VLB 486 😀

Here is the new target config :
- AMD 586DX5-133 ADZ Write Back working
- Shuttle HOT 433 v4.0 faulty ?
- 256KB cache working
- 64MB EDO RAM working
- S3 Trio64 V+ working
- Sound blaster AWE32 CT2760, 32MB RAM, XR385 Wavetable untested
- Sound Blaster 16 Pro CT2910 untested
- Adaptec AHA2940AU PCI SCSI working
- 18GB seatage 10k RPM SCSI HD working
- Yamaha 161040 SCSI CDROM untested
- DOS 6.2 + Win 3.11 untested/non bootable
- win 95untested

Nice hardware! Your motherboard is so hot!

Integrated FDC can usually be disabled in BIOS, ISA I/O cards are cheap and go with 1FDD, 2 IDE, 2COM, 1 LPT. They are usually configured with a set of jumpers, so you can disable every item except FDC.

Did the try flashing the bios on your 2940U2W controller?

Maybe your Trio64V2 card can be repaired by recapping?

Ok, I'll try this if I can be sure the MB is faulty.
I'll mount one of my PIIs to tests with another motherboard, same floppies and floppy drives.

Nope, didn't try anything on the 2940. Same thing, i'll try it on the PII.
For the trio, there's no cap on it :

we replaced the top left (V2/DX) with the bottom left (V+)

I am not surprised you are having odd configuration problems with a HOT-433 motherboard. My experience with these boards is that one minute it seemed to work fine, and the next, it was not. Sometimes it would go a day working fine, then the next it was not. Or sometimes I'd have to do all this goofing around to get it working with certain hardware (like you are doing), and then it would just refuse to work. It was as if the board is haunted.

It sounds to me like you are having issues with the Super I/O controller. I have a Biostar MB-8433 with a floppy controller that went bad after years of reliable service. I found that the only way to get an ISA floppy/IDE/LPT/Serial card working was to use one which had the same super I/O, or compatible chip as that was on the motherboard. I also had to leave the floppy controller ENABLED in the motherboard's BIOS. I'm not sure if these steps are the same with the HOT-433, but it would be worth looking into if you run into issues.

What if you try using FPM RAM instead of EDO? I found the HOT-433 v1-3 always worked better with FPM. I have not extensively tested v4.

I've been working on this system.

Tried FPM mem. Didn't improve.
Tried 32MB instead of 64, same.
Problem was ... the floppy drives. I actually have 4 broken drives. I installed the one thatr works in my VLB machine, and it installed DOS flawlessly ...

So, my 2 486 are on the right track. Next step is sound cards, and then benching/overclocking/playing 😀

Yeah. 1.44mb drives are terribly unreliable.

What I never understood why the 720k drive in my Amiga (without a dust cover) never failed me once in the 20 years I owned it.

Funny, the 1.76MB HD drive in my Amiga 4000 seems to work fine aside from a dirty DD/HD detection sensor. Those Chinon drives were never known for their reliability either. You'd think they would be more trouble given the precision needed to read/write GCR disks. In HD mode, the drive spins at half the speed!

One of my 2 A500 has a dead drive too 🙁

Did you try an Adaptec 2940uw it is one of the best supported pieces of hardware!

Nope, I just have U2W and AU sadly.

I'm not sure if this is on your adgenda, but if it is, let me know if you can boot into W2K using that 2940AU card.
