CP/M Ready Z80 Single Board Computer, ZRCC, CPM SBC, Compact Flash, EPM7064S 42
Item History & Price
| Reference Number: Avaluer:27171632 |
This is a newly designed CPM-ready Z80 single-board computer. It is ZRCC which stands for Z80-RAM-CPLD-CFdisk, named after the 4 major components of this design. This new design explores new design concepts that uses the compact flash disk as EPROM and combinatorial logic fabric in CPLD as a small bootstrap code resulting in a fast yet simple Z80 SBC for CP/M. ZRCC is likely the simplest yet fastest CP/M-ready Z80 you'll find. The major features of ZRCC are:
... Z80 running at 22MHz 128K RAM in four 32K banks EPM7064S CPLD Compact flash drive CP/M-ready, CP/M 2.2 and CP/M 3 26-pin I/O expansion (RC2014-lite) 86mm x 50mm 2-layer pc board
The entire design information for ZRCC is published at https://www.retrobrewcomputers.org/doku.php?id=builderpages:plasmo:zrcc:zrcc1
The overall dimension of the board (without the USB adapter) is 2" x 6". It draws about 150mA at 5V, typical. This item is fully assembled and tested with CP/M 2.2 and CP/M 3 software installed in the 64 meg CF drive. It is ready to run with external 5V power through the 2.1mm X 5.5 mm power jack and USB connected to the included USB-to-serial adapter. Set the terminal emulation to 115200 N-8-1, no hardware handshake.
You will receive the item in the first 2 photos of this auction including the compact flash disk, USB-to-serial adapter and USB-to-2.5mmX2.1mm power cable.
