ZRuno, CP/M - Ready Z80 SBC Fo Arduino Mega Enclosure. Compatible With ZRCC
Item History & Price
| Reference Number: Avaluer:27175886 |
ZRuno is a close cousin of ZRCC that is also currently for sale. It is designed specifically for the acrylic Arduino Mega enclosure. ZRuno software is fully compatible with ZRCC. Hardware is same as ZRCC except there are 10 WS2812B RGB LED added. The original ZRCC monitor software is modified to drive the WS2812B RGB LED. The 4th picture shows the LED light pattern when power is initially applied. Different monitor commands will display different LED... light patterns.
The hardware is very simple yet very fast with the 20MHz Z80 overclocked to 22MHz. ZRuno is likely the simplest yet fastest CP/M-ready Z80 you'll find. The major features of ZRuno are:
* Z80 running at 22MHz
* 128K RAM in four 32K banks
* EPM7064S CPLD
* Ten WS2812B RGB LED
* Compact flash drive
* CP/M-ready, CP/M 2.2 and CP/M 3
* 26-pin I/O expansion (RC2014-lite)
* Designed for Arduino Mega enclosure

The overall dimension of the board (without the USB adapter) is 2.5" x 6.5". It draws about 150mA at 5V, typical, however with the 10 LED at full intensity, it can draw 400mA. 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.
