This is definitely a Mac-compatible (hardware-wise) on a PC ISA card. I remember when Hydra Systems out of Silicon Valley (San Jose I think) introduced the product back in 1991. All you needed to do was to add some Mac 128K ROMS (ala Atari MagicSac) and you could make your PC run Mac software. Tom Owad would be a great source of info...he's been interested in Mac Compatibles for a long time...I gave him my Akkord Mac compatible. (which is probably something I'll regret) If you find a MacWorld with the NuTek Mac compatible article on the front cover, you should find a reference to the Hydra board in it. -Chandra -----Original Message----- From: cctalk-bounces at classiccmp.org [mailto:cctalk-bounces at classiccmp.org] On Behalf Of Chris M Sent: Saturday, August 20, 2005 1:33 AM To: General Discussion: On-Topic Posts Only Subject: Re: Hydra Systems : Mac on ISA card ?? Doubt it's any sort of Mac on a card, though it does appear to be a reasonably complete 68K based system. Got any pics? Can't help with the drivers. There was a Circuit Cellar article (BYTE) probably in the late 80's that described a project based on a 68020 IIRC. It may have been a graphics board though - for an IBM PC. --- Bernd Kopriva <bernd at kopriva.de> wrote: ____________________________________________________ Start your day with Yahoo! - make it your home page http://www.yahoo.com/r/hs

Hi, you can find a picture of the card here : http://cgi.ebay.de/ws/eBayISAPI.dll?ViewItem&item=5223833565&rd=1&a… The card you are thinking of is a Definicon DSI-780 card, which in fact is "only" a processor add on card (processor, memory, own runtime environment), whereas the Hydra card at least was announced as "Mac on ISA" ...
