Does anyone know what a DEC AD0L-A is? Looks like some sort of A/D equipment. Mounting panel holds a number cards and has a small power supply near one end. Cards present (looks like a bunch are missing, from the amount of wiring on the backplane) are: A220 A708 A862 bipolar high speed A/C convertor G701 M100 M111 invertors M161 binary to octal convertor M216 flip-flops M602 pulse generator M636 Anybody know what the mystery cards are? Thanks, Bill
