There were actually two different boards, the M7800 and the M7800-YA. The -YA model didn't have the chips for EIA; it was strictly 20 mA loop and was used in the DL11-A and DL11-C versions. The DL11-B, -D, and -E were all the M7800 board and had EIA drivers as well as current loop. That's really not my point, though. The DL11-E was a more expensive board than the others because it had modem control -- DTR, RTS, CTS, DCD, etc. were brought out to registers. It was only a jumper change (well documented in the engineering drawings) to convert a -B or -D board to an -E though. ---Bob "What, I've voided my service contract?"
