|Heathkit H8, ca. 1981|
|CPU:||Z80 @ 2.048MHz|
|Floppy Drives:||Two SS hard-sectored drives at 100KB each (Z87)|
This system has the following boards:
The HA-8-6 Z80 CPU board was heavily modified, for unknown purposes. I was forced to remove all the modifications and restore the board to its default state. The DG-32D RAM board also had a bad 4116 chip and the front panel had a bad 2N3904 transistor in the reset circuit.
The last three pictures show the system running CP/M 2.2.04 from a Z87 drive unit. I've configured the H8 with a Z80 board from a recent Norberto Collado design, and the H17 controller. The Z80 board has 64KB of RAM, two serial ports and a real-time clock. Details, here.
