Industrial Micro Systems -
This was the main IO board for the IMS
5000 and 4000 series computer systems. It was called the 440 IO Card.
The board could accommodate up to
4K onboard EPROM (2716). There had a programmable interval timer and clock
((8253), two UARTS (6402's) running at BAUD rates from 75 up to 19.2K with RS232
I/O as well as 3 parallel ports using an 8255. Nothing particularly
special or novel about the board. It could via
jumpers (JD, JE & JF)
accommodate a 2708, 1716 or 2732 EPROM. There were good interrupt
signaling options as well.
