Although not quite a VCS on an S-100, this card has been described by one source close to Atari
as being a development card for designing VCS software using a Cromemco S-100 Bus computer system.
This information has not been confirmed by any other source close to Atari so its true use is still questionable.
Any assistance from any ex-Atari employees who may have worked with this card (or in fact designed it),
please contact us here at Atari Museum and help us understand more clearly the use of this particular card.
