Has anyone ever come across any VME graphics cards? I have an Atari Mega STE with an unused VME slot, and would love to have some higher resolution output for that machine than what the stock ST chips provide.. Just figure I'd ask..

The Atari VME slot is a single connector I'd guess, given the size of the machine. There were frames to put SGI desktop video boards in the larger deskside and full rack SGIs via the VME slot side... but they were usually 2 connectors I think, and the video card set (ELAN from Indigo?) wouldn't fit. Plus you'd have to write all the software to make it work. No idea if there were VME accessories ever produced for the Atari ST computers. Probably would be easier to go VME to PCI and use a WinTel graphics card after writing software to drive it. (I actually have a TT030 and I think it has a VME slot as well, but it's empty.)
Thanks - there were drivers written for several VME cards to work on the TT or MegaSTE. ET4000 (Tseng 4000) chipset cards for example are supported already.. Found it - here are a list of VME cards supported on Mega STE and TT: http://wiki.newtosworld.de/index.php?title=Grafikkarten On Wed, Jun 21, 2017 at 3:37 PM, Ethan <telmnstr@757.org> wrote:

The ET4000 was my very first VGA card, ISA style. I remember having to Hex Edit deluxe paint II to get that sweet 800x600x16 color mode. Woah: http://web.archive.org/web/20070202082609/http://atarihacks.cjb.net/ Under video. Looks like there is a hack to wire the ET4K ISA card into VME slot. Looks like there is a GAL file as well so it's more than just wires, some logic shifting. Perhaps the same thing as that NOVA adapter. Fascinating!
I see the Mega ST ET4000 Hack -- here's the updated URL http://atari4ever.free.fr/ It's a pretty impressive mod -- it's actually not a VME Mod but something that connects the ET4000 to a plain ST.. (so it could technically be wired into a regular 520/1040ST too). Here is a VME to iSA adapter intended for MEga STE/TT - http://freenet-homepage.de/68k/pdf/nova_adapter.pdf I used to also have an ET4000 - my first 'fast' graphics card for DOS. Would run up to a 16 mhz ISA Bus (20 mhz with artifacting)... On Wed, Jun 21, 2017 at 6:19 PM, Ethan <telmnstr@757.org> wrote:

Found working link of that: ftp://ftp.pigwa.net/stuff/mirror/ataritt030.info/upload/schematy/nova_adapter.pdf Fascinating!

THat's pretty hardcore :-) Mine was on a 386-25DX Gateway 2000 with a Micronics motherboard, 4MB of RAM. Never tried to change bus speeds or anything, it was an expensive machine didn't want to break it. I do remember having switches hooked to the sound cards to adjust the IRQs though.

Yes, my TT030had a VME card inside. I think these were always rare and expensive. Some (old) discussion here:- http://atariage.com/forums/topic/77307-vme-graphic-cardswhats-the-deal/

Some info on the slot here:- http://dev-docs.atariforge.org/files/VME_Spec_7-19-1991.pdf

There were VME to ISA adaptors that allowed an ETI4000 card to be used iin the TT... http://thebigconsultant.com/probe/hw-nova-tt.html Dave Wade
