If somebody wants to provide the server space, I will dump every ROM I can. By the way, here is the image for Mach32. Typo in ROM content description. Should read ATi Mach32 Graphics Ultra Pro ISA

I do have a Mach32 VLB. However, you should be aware that there are more ISA and VLB versions of Mach32 than Mach64. My two VLB cards are the full retail VRAM versions. There are also premium and cost reduced DRAM models, as well as several OEM specific models which usually have lower quality …

Perhaps, but from the press release it gave the impression the card could be purchased as stand alone. I'm sure it was offered in packages, but I have not been able to find any information that would help me so far. I'll give the linked in guy a shot. I'll have another look at the card to see if I …

Here you go. Let me know how this works out for you. I have an ET4000W32P VLB card that is showing the same behaviour, and I suspect a bad ROM.

Eventually, I went along... but I have always had a soft spot in my heart for the old days! Funny thing is, that that same soft spot has grown to include not only DOS, but Windows 95, 98, and even XP. Weird how it got to be that way. I still can't accept 95, 98 or XP. NT4 and Windows 3.x are where …

Okay, I have some time after work today so I'll do my best to take care of it (assuming that I can actually get my system to boot with all these cards). My only remaining true VLB system uses a picky SiS 406/411 chipset.

4MB cards are basically useless on ISA because the time to redraw the screen at high resolutions is too long. With 2MB you can run 1024x768 with 16-bit colour, which is way more than you will ever need on an all ISA system. As far as I know every card with the ET4000W32i or ET4000W32p can do memory …

I just uploaded another handful of photos to my web album. It appears my AWE32 is the CT3980. My old one was a CT2760. I'm not familiar with the Genoa Phantom. I've never owned a Genoa card before. But looking at the photo, it looks like the layout and build quality are decent. Are you able to get …

Not sure about the W32P card. I can look into it. Do you have anything interesting to trade? BTW, I don't hate AWE32s, but I prefer not to use them since they have very noisy output and have an audible hum when connected to an integrated amplifier. I still have an AWE32 with real OPL3 actually.

Interleaving was available on better quality 386 and 486 boards. I think there are even 286 boards that can do it. I have five motherboards that support it. Two are VL/EISA 486 boards based on SiS 401/406 chipset. One is a pure ISA 486 based on Symphony chipset. One is a true American Megatrends …

The Alaris (IBM) boards are all of excellent quality. I would guess that despite the SLC2-66 not having true VLB slots, performance wise it should be at least 90% of a true Intel DX-2 66, mostly because this board uses memory interleaving whereas most mainstream 486 boards do not. I had a friend …

I forgot. I still have one more hybrid board left, but it's an IBM 486SLC2-66 with VLB, so the VLB slots are gimped even further with a 16-bit data and 24-bit addressing restrictions.

vintage-computer forum. I don't think the project would be time consuming for somebody who knows the layout software well and has dealt with handling small orders before. The problem is convincing such people that this would be a worthwhile effort.

No, you absolutely wouldn't be able to desolder DRAMs from old SIMMs and put SRAM in its place. I'm talking about designing an entirely new PCB. I know this is possible, because over on VCF they have built SRAM memory cards for 8088s and PCjrs.

ALI; 15ns 512K L2 cache, 50ns 128Mb EDO 72-pin simms Opti; 10ns 256K L2 cache, 60ns 32Mb FPM 30-pin simms I suspect that DRAM is more suited to dos, with VRAM being more for GUI and 3d related program. 10ns cache is going to be tricky. It seems to have a pretty high failure rate, so you might need …

You have owned some really good gear... i'm surprized you let some of it go, especially the #9's!!! I'm curious though, why do you not like the AWE32's? First I moved from the US back to Canada, and then from Canada to China. Things had to go. I'm lucky I still have what I do, which in my opinion …

I did have an ALI 1429, but sadly it didn't have a VLB slot. I did have an OPTi 495SX board with VLB, and that was a pretty solid 386 motherboard. It had 2 VLB slots. https://picasaweb.google.com/misterzeropage/FormerlyOwnedPCParts#5078750894097353090 I traded it for something better though. At the …
