C > CROMEMCO  > Z-1   


The Cromemco Z-1 uses an IMSAI chassis, with 22 card slots and a 28 amperes (about 300 watts) power supply. The major innovation of the Z-1 is the use of the 4 Mhz version of the Z-80 processor. It is also equiped with its own 2708 type EPROM burner card.

Like the IMSAI, the Basic version of the Cromemco Z-1 is programmed through the front panel switches, and results are read from the front panel leds... Hopefuly, it is possible to connect a standard Video terminal through the serial port.
