Wanted: Mach64/32 ISA card

Post by DoG » Wed Aug 01, 2018 3:34 pm

Searching for a Mach64 ISA graphics card. Preferably 4Mb of course, but 2Mb is fine too. Also searching for a Mach32 ISA card if I can't find a Mach64. It's for a Nova/VME board connected to my TT030 as you probably already guessed.

Located in Sweden.

As you have probably noticed, The few ISA Mach64 cards on eBay are ridiculously priced. Funnily enough, after months of searching, I found a 1MB card in Sweden for a fair price. I promptly upgraded it to 2MB. So the pickings are slim.

The only 4MB card I know has the additional 2MB on a separate card. Seen below:

That also happens to be a supported DAC. See bottom card in this link: https://silicon-heaven.org/atari/nova/TT030/Mach64/

If you can get any Mach64 for under 100USD do it without hesitation.

Nice. If I get an hold of a 1Mb card I can contact you perhaps and you can tell my how to upgrade it to 2Mb?

I know that it has a extra card you slot on it to get 4 Mb. Rare as well, as you pointed out. These 2Mb extra memory cards seems to come in different types and only works on the right card type? ie PCI, Vesa, ISA? Probably just different memory speed and such.

I just found these, from US sellers:

http://www.thebestpartinc.com/109-19301-10.html
https://www.amazon.com/gp/offer-listing ... ition=used

I don't know about international shipping from the first one, but the Amazon seller appears to offer it. You would perhaps need to pay VAT to import it, but the original price is certainly not bad.

The ATI 109-19301-10 aka ATI EXM193 is a Mach64 with 2MB VRAM. Unfortunately, at least according to Idek's Nova Driver page, EXM193 doesn't necessarily always have the same DAC on it, and I don't know if every DAC found on that model card is supported. The picture of the card on Amazon isn't great, but it does look like it's the CH8398A DAC, which is supported, but don't necessarily take my word for it. You might want to contact the seller to verify.

EDIT: Looking closer at that card on Amazon, it looks like the RAM sockets at the edge are unpopulated, so it's actually probably a 1MB card. Buyer beware. Ask the seller questions if you pursue it.

Yeah best bet is to set up a search notification on ebay (which is how I found mine) The chances of you finding one for sale on an Atari forum are slim to none. I got very lucky and found one for around $100, which I think is a good price compared to some of the other prices I've seen.

Check out Idek's site for drivers/DAC support.
