With the single page that Mattis did provide, I was able to connect a Centronics interface printer to the M8365. I added the interconnect cable wiring to my web pages (which are currently down). I expected to need some glue logic between the two, but this board has a STB L signal that is a fixed length pulse. The printer ACK L connects to DEMAND to set the printer flag. The printer flag doesn't get set before the first character, but the handler assumes the flag is set on entry. It strobes the character and then waits for the flag to get set by ACK L, so it just works. Chuck
