I have an SBUS card made by AT&T copyrighted 1994. It has (2) 15-pin
jacks (similar to VGA/SVGA ports). Onboard the main two processors are an
AT&T ATT65658 and a Motorola MC92005DH. There is an AT&T ID/Serial number
sticker that identifies it as AT&T part number CMA 993A 1:2. Does anyone
have an idea of what this card is or what it does?

Thanks,
Dave
