Cromemco - PRI Board
The Cromemco PRI parallel printer
interface board was designed to permit the simultaneous operation of the
Cromemco 3703 or 3779 dot matrix printer and the 3355A fully formed character
printer.
Features included automatic ribbon
control for the fully formed character printer, and supports interrupts. On
these old printers the ribbon had to be raised and lowered for proper character
printing. The PRI board had a timer circuit so the ribbon was in place before
the character was printed. It would stay raised until no more characters came
within a 1 second timeout. Although the I/O ports were factory set they could be
easily changed by the user.
