Re: Diamond Stealth se - ram upgrade won't work?
Posted on Today, 14:45
The ram chips I tried were not reported, neither the chips from the 5428 when I swapped them. I guess I could see if I've got some more chips the test... To be continued.

That would be a pity... But could be soldered on if I knew what is needed here 😀 Any ideas? Would this be the issue, or would these be used for something else? - R70 - R114 - RP1 I also noticed there are a lot of other components not places, so maybe this wouldn't be?
Re: BIOS image collection - requests, discussion etc
Posted on Today, 10:42
I don't know for this thread, but I'm interested by it for UH19 :) Can you give me at least some details about your motherboard ? What UMC chipset does it use, does it have 30 pin slots as well as 72 pin slots or just 72 pin slots ? There are two candidates on UH19 so I'd like to know which one is …

Maybe a silly question. I'm about to upload my BIOS from my Aquarius MB-4DUV rev 3.1 somewhere on the forum, but I'm too lazy now to take my whole computer apart and take a photo of the motherboard. Does the BIOS still being in the 486 BIOS collection thread? Or would you like it somewhere else to …
Diamond Stealth se - ram upgrade won't work?
Posted on Yesterday, 23:40
My fastest vlb system contains this hardware: Aquarius MB-4DUV, cyrix 5x86-100, Promise cache controller (VLB), 32MB ram, some VLB i/o card for com/lpt (ide and FDD are disabled in favour of the Promise). Now I have 2 graphics cards I really like; - Cirrus Logic GD5428 with 2MB - Diamond Stealth SE …

Hm why not add 64Mb per VSA :-) Voodoo 5 6500 ! Or this :P https://i.imgur.com/byqK4Kd.jpg I'd like to get that one into my 1050MHz BX computer :D It would probably outrun an AGP rx3090 xD Seriously, would that be "doable" in any way? Or even 6-8 cores? Would it have any practical purpose besides " …

The floppy over pcmcia is probably a good start of you can get some fairly ok floppy disks. I prefer / use the interlnk approach from time to time, it works pretty good. Don't expect high transfer speeds, but it's certainly not bad over lpt. It is available from ms dos 6.x and pc dos 5.02. Get a …

Definitely interesting stuff 😀 Would be valuable along with a simple/cheap PCI/ISA tester. I can imagine one with extension cable to get there segment display onto a front bay as well 😀

Got it 😀 64kB of what looks to me like character rubbish 😜 the program works perfectly. I've also extracted some strings out of the file.

Sorry for re-necroposting. Recently I got this FIC 486-J motherboard. It was failing to not due to the empty Dallas, but that's fixed now. I put on 8x 1MB ram. It seems totally stable and works as expected, even with the ISA bus at 10MHz. Actually a little faster than I expected without L2: about …

Thnx all! :D The switches are definitely not in their right position, that's something I still have to figure out. The system gives me some I/o errors on boot. Thinking of it: that may also create a conflict with the keyboard perhaps... 256kB to 640kB is something I'd like to do if I get it up and …

I'm back! We just had our annual week of snow, so all week long I've been towing a little sled with my son thru the streets. I did make some nice pictures of the computer and it's internals, and a little video with the lovely sound of the hard disk. Some photos were about 20MB and I don't think the …
Multitech MPF-PC 552 misbehaving

I've got this Multitech MPF-PC 552 for about 4 years now, but never got it to work as expected. It's an IBM PC clone. It came with original Multitech keyboard and Multitech monochrome CGA screen (composite). I think it's something special, because I have only seen exactly one more. Multitech MPF-PC. …

What is this longer PCI slot (IBM netvista)???
Posted on 2021-01-31, 16:05
Today I've finally made some time to take a good look at the IBM netvista 6059, Pentium 3 933. IMG-20210131-WA0003~2.jpeg I've got it for over a year but never really took the time to open it up. After opening the case there's a longer version of the PCI slot visible. It is not a 66MHz PCI-X as far …
Re: New PS/2 compatible mouse options?

Not very helpful, but I think obsolete hardware with obsolete technology has become cheaper and cheaper over time. For that I doubt there are many 'better' quality alternatives (and more expensive) available. After all, most modern consumer stuff doesn't have ps/2 any more, usb is the thing to have …
