Mini keyboard for Z80

Mini keyboard for Z80
Depending on the application of the 'Multifunction 280 card', a basic set of switches to control the program flow may be required. Also, in some cases, the PC/XT keyboard that can be connected to the card may prove a little too bulky to be carried around. The keyboard plus LED tndication described here is connected to PIOA on the multi-functton 280 card. The 10 keys are arranged horizontally on a board fitted behind the enclosure front panel, and serve to control functions determined by the user software.
