I recently purchased an acermagic v18 off ebay to play around with, but issue is I can find practically nothing online about this card. I managed to track the drivers down on some sketchy chinese website, and they seemed to install fine when I tried them in 86box on windows 3.1. I threw them up on …

Of course 5v and gnd can be taken from any pin with that signal, the only thing left is data plus and minus This thing also exists, unclear if it is using the port signal or not though.

Is it necro-ing a thread if the last reply was a few months ago? Either way, was thinking of picking a pci to isa adapter up and wondering what could be used with them? Would a video card work?

It's a rev 1.1, so looks like i can't go above 166. Would that still be the case with the interposer? UPDATE: So i got it to boot with the K6 233 cpu by setting the bus speed to 60mhz. It shows it as running at 210mhz, but i'm not sure that's right since changing the multiplier jumpers doesn't …

Bought a small lot of isa cards and this was among them, interesting thing about it that the crystal cs4239 chip is in a socket. Cant say ive ever seen a sound card with a socketed chip before. Was this a thing on sound cards, and why would you need a socket? IMG_20211020_111640_474.jpg IMG_20211020 …

Maybe these on the floppy controller board were of a particularly bad batch, while the others might be of a good one? So, are these of exactly the same optics (color, print, form) or are there differences that could one make hope for another, possibly better quality? They looked to be similar …

I run debian 11 mate on an ibm thinkpad x31 with a 1.6ghz pentium m and i think 1gb of ram(maybe less). It works well enough, chugs a bit on some websites though. You can even watch youtube videos at 360p if your patient enough to wait for it to load

Finally got around to figuring out why my compaq portable 1 wouldn't turn on, and ended up being a bad tantalum cap in the floppy controller. Took it out, machine powered on. Put the controller back in, the cap blew up and spewed molten cap guts everywhere. Nothing was damaged but it sure was quite …

I tried formatting a brand NOS floppy disk and fails saying that sector 0 is bad. Does it say "sector 0" or "track 0" is bad? If the error mentions "track 0" then the issue could be the track 0 sensor in the drive not working or the ribbon cable/connector could have a bad connection on the track 0 …

I tried the equally non-functioning floppy controller that was sent as a replacement for the first, and set the address to 0xf0000 and plugged it into my xt 5160. I can see the rom being loaded with the DEBUG command, and the sequence identical to what i see when i load the bios in a hex editor on …

Sorry about that! at that area it was more or less a repeating string of 36 and 00. I dumped the bios of the card, and compared it in a hex editor and the beginning area was nothing alike. For a control I plugged it into my 5160 and ran debug to see what was loaded in the address space of the …

I looked in checkit as well, and can confirm that is a free space of memory I can't make sense of the string, as debug uses the …

Or too much ripple. AC superimposed on the DC Wouldn't other cards/components be affected as well? I have an xt-ide card, vga card, and an adlib card in it and all of them seem to be working fine. How can i test it that's the case? Yes the PSU could be the issue but my feelings also look to you not …
