iXMicro TwinTurbo 128P8 Er... that's like the 128M8, but with DE15 VGA instead of DA15 Mac isn't it...? I have the sinking feeling I had one and gave it away a while back It's possible yes that could have been one. iXMicro TwinTurbo made the 128P8 for the PC market. I haven't even seen pictures.

Without a board picture I just assume it is vapourware because that was common at the time. In fact of the cards I listed, I have pictures of all of them except the iXMicro TwinTurbo 128P8 which I have seen two mentions of in magazines of the era. If you want cards that should exist but we can find …

Fpga cpu replacements with modern instruction sets I was thinking this the other day. The FPGA today are far more powerful than anything in the retro days. We could have them do anything. What I really want right now is a math coprocessor for my UMC U5 or an FPGA replica of the unobtainium UMC U5 …

Ooh, another IIT board... Any chance you could dump the VGA BIOS ROM? I have a different one (a Puretek PT-2072 with AGX 016A chip), but have hit a brick wall twice trying to get VESA working fully. Hercules has VESA drivers which look interesting, but they refuse to run on non-Hercules cards. …

Thanks you every one for posting these, but let's limit it to the cards that are really obscure, where they are not on vgamuseum and you can't find proper pictures of them anywhere. Well that excludes me by default 'cause all my cards are up there. Now that's something. I wonder if some cards were …

I bought a Hercules Graphite VL Pro , not because it is good, but because it is odd. It claims to be able to handle 2MB but with stock 1MB. The only upgrade spots look to be two DIP-24 holders but even the DIP VRAM I can find is 256 kB only and in a ZIP package. Was DIP VRAM ever made? I want to …

I was looking at reviews of the Hercules Graphite Pro VL vs the Orchid Celsius and the primary difference is the Orchid 2 MB RAM. I figure upgrading the memory would improve the IIT AGX-015 from a low-middle card to acceptable.

So there is no information on this but I have this wonderful new AT board and it has some weird "Green PC connector" with what seems like an enable switch on JP15 but a second set of pins for JP5. On other boards of the time, the "Green PC connector" seems to be a sleep SMI (system management …

parity or ECC memory will generally happily run as non-parity/ECC, but you will not have the benefits of error checking (parity can identify single-bit errors, ECC double-bit errors) if you do. Controllers that don't support parity generally don't care if memory supports it or not. Conversely, some …

I bought this ABIT AB-PG5 because it is the only system built for an obscure VGA card. It seems to have a PISA bus in it but pre-dates 1996. What can I stick in this slot?
