This card is essentially a Single Board Computer (SBC) based on the Z180 CPU. It only needs a power source, a reset single, and a terminal to make a complete CP/M computer.
The card uses a Z180 CPU for good performance and RomWBW firmware for a robust implementation of CP/M with support for a wide range of hardware.
The kit comprises parts to build a Z50Bus compatible card with these main features:
Z180 CPU running at 18.432 MHz 512k byte RAM 512k byte Flash containing RomWBW Two asynchronous serial ports SPI port primarily for SD card Optional items:
Micro SD card adapter Serial adapter to USB USB cable, A to mini-B, 18"/500mm long Adapter cable, 6-way, 8"/200mm Additional accessories, such as serial adapters and cables, can be found here.
RomWBW is a robust ROM-based operating system for retro computers. It includes CP/M 2.2 and Z-System and supports a wide range of hardware, including SD cards and Compact Flash cards for storage. RomWBW has been provided free of charge by its author Wayne Warthen. Thank you, Wayne, for providing this and all the support.
The full kit includes the printed circuit board and all the components needed to make the card, as shown in the first picture. Other cards and backplanes shown in the other pictures are not included. You will require tools, solder, and cleaning materials to assemble this kit.
To use this card you will need a Z50Bus backplane, a power source, and a reset signal. The recommended modules are SC501 (or similar) backplane and SC502 power and reset card. Alternatively, you could use a backplane with a power input and a reset circuit, such as SC513. In each case, you will need to provide a D.C. power supply.
