Advert from Byte magazine (january 1977) said :
|
|
|
|
...It gets its speed and power from a selected version of the new Z80 microprocessor that can operate at a 4 Mhz. clock rate (The Z-1 also lets you switch to 2 Mhz. to be compatible with older systems)...\
|
|
...The Z-1 offers you all kinds of peripherals and softwares. It uses the standard ''S100'' bus supported by over a dozen manufacturers. And all Cromemco peripherals (PROM memory and programmer, Ram memory, analog I/O, color TV interface, etc) just plug into the Z1's sockets...\
|
|
... The Z-1 comes completely assembled ans tested. It's a quality, commercial grade microcomputer. It is not available as a kit.

The Z-1 had 3 significant changes from the Imsai 8080 upon which it was based: 1) The Motherboard was replaced with a Cromemco Blitz Bus (the rare version of this bus with the front connector offset to accept the front panel) 2) the CPU was replaced with the Cromemco ZPU, and 3) the film in the front panel was replaced with one that says Cromemco Z-1.
|
|
|
|
The Blitz Bus was supposed to handle higher frequency better, to support the 4 MHz ZPU.
|
|
|
|
On my Z-1, the fuse was relocated to the rear panel. I suspect this was also done by Cromemco when they created the Z-1, but I don''t have confirmation.

This is the computer from the movie War Games (1983)
|
|
|
|
The company Cromemco is still building these\
|
|
on there website, for 8bit programming needs\
|
|
(they have some that run at 90 mhz)

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.
