Compupro Interfacer 4 S-100 Board, selling as-is.
The Interfacer 4 was fully software compatibility with the Interfacer 3 as well as the ability to intermix Interfacer 3 and 4 boards at the same port addresses. Additional features included 3 fully programmable asynchronous serial channels, 2 of which were capable of high speed synchronous transmission and one capable of current loop operation, five RS-232 handshaking lines per channel plus bi-directional clock drive...rs on both the synchronous channels, a pin compatible Centronics parallel interface port with the full complement of handshaking lines, a universal parallel port with 16 data and 3 handshaking lines, expandability to 32 users with eight boards using only 8 port addresses, a flexible interrupt structure with full maskability and pending status on both transmit and receive interrupts, and a conservative design for operation with most CPUs operating to beyond 10 MHz.
