Thanks. I'm used to repairingolder stuff som 74hc04 is the kind of marking I expect to see. I found an F04 on a graphics card and cannibalized it. Still no activity at all. I guess there are more blown ICs. I'm gonna remove the BIOS socket and remove the rest of the ICs to test them. It's a pain to …

I ordered some SN74F04 hex inverters. They look similar.

I've got this Abit VH6T that I recapped and it still doesn't work. It also had a faulty BIOS ROM so I replaced that and progarmmed it but still doesn't work. After some closer inspection I found a blown IC under the BIOS IC so I suspect that's the fault. Possibly because someone inserted a BIOS …

I put it up on Cults3d for others to make. It's my design: https://cults3d.com/en/3d-model/various/itx-s … case-tahustvedt Sorry I still can't reply to PM's.

I'm not allowed to use PM's as I'm too new here. I don't intend to make these for sale, just put them out for others to make for themselves.

I got the PCBs. I had made four errors with the middle drive connections. After fixing it works fine. I'll have to reorder and check the new PCBs too. They identify as slave and master like they should with the Panasonic drives I'm using. I can't find any supplier for JAE connectors like that, …

Here are the printable STL files: https://cults3d.com/en/3d-model/various/2x-an … 4-bays-for-pc-s I'll put the PCB up on PCBway's community site if it works when I get the prototype.

My NEC 4x CD changer, although cool, is unbearably slow. For the heck of it I decided to try to integrate three old laptop IDE optical drives in one 5-1/4" bay. It fits and works much better than a CD changer. I had to rewire the transposers to give slave and master. The three CD-audio outputs are …

I got L2 Cache now and it didn't change anything. It was a long shot. Guess the video card is just a bad choice.

I have built many GBScontrol units with various GBS-boards. It's amazing for Amigas for example but barely works with PC resolutions. MY 60 Hz BIOS page tends to work but not 70 Hz DOS, except sometimes it does... barely. I don't think the dev has a retro PC to test with so it's not a priority but …

I tried turning off L1 cache now and that fixed the graphics in Turrican 2, but it's too slow without L1 cache. There's no L2 cache in the machine. I have ordered some for it so maybe that changes things.

Hi. I have a problem with my old IBM 486 with a 6381 motherboard with on board Tseng ET4000 W32 (VLB). The colors in some games and many scenes in demos like Second Reality are messed up. Things I have tried that changed nothing: Different CPUs (486 DX2 66, Pentium 83 OD and AM5x86 133) Different …

I tried it on my (486) IBM with a Pentium 83 MHz overdrive. The speeds went from 108 W 109 R to 365 W 375 R (typically). Much appreciated. :) Isa-02.jpg I tried setting the % to 1 and 2 but it just locks up when I try to do anything on the card. I also tried %255 and it corrupted the USB stick and I …
