The Hades computer was built by a company called Medusa Computer Systems
they offered an Atari Clone but sadly do no longer, infact, I dont think anyone still makes Atari Clones currently
(XTOS doesn't count yet,) Anyways Here is the info I was able to give about the Hades Computer.

Note: The Medusa above is a REAL medusa, But I am pretty sure they just sent you the Mother Board +cards
and you had to go and buy a case yourself. But this again, I dont know for sure.
Also note: The Medusa being somewhat newer will had odd stock stuff in it, so there is a good chance its wrong here.

It came in two varieties, 040 and 060 I think
