Instead of a raster graphic display output and classical keyboard, it had a calculator-style nine-digit seven-segment red LED display and a 25-key calculator-type keypad with hexadecimal and function keys (including hardware '''RE'''set and '''I'''nterrupt). The PMI-80 had 1 KiB of ROM (expandable to 2 KiB) and fixed 1 KiB of RWM. Eight (expandable to 32) I/O lines were provided for user along with complete system bus. Connected could be e.g., a card with a DAC of 0–12 V range.
