who can identify this vintage card - "DAD-48" ?

[Steve Thatcher]

it isn't scsi. First of all it is a Pro-Log STD bus card. The card is an 
analog to digital and digital to analog convertor. The ad667 chips are 12 
multiplying digital to analog convertors which gives you four analog 
outputs for the board. I couldn't make out the Burr-Brown part numbers, but 
I suspect that they are sample and hold amplifiers or analog switches that 
take eight analog inputs and presents them to the TSC800 chip which is a 15 
bit analog to digital converter. Just a guess anyway...

best regards, Steve Thatcher
