Never used a Z8 MCU before, but when I found that chip "forgotten" for decades and started to read the datasheet and various documentation, I realized that it was a great MCU and wanted to see it in action... So I designed the board...

Too good to rest in a box...


Please note that this board * is not * for a Z80 CPU, but for a Z8 BASIC/DEBUG MCU (marked as Z8671 or Z0867108).








Because this board use only a SRAM with a backup battery for data retention, you don't need any legacy EPROM programmer.


The specs of the RC-Z8BASIC are:

128KB SRAM with battery backup, RS-232 port, serial-USB adapter port, GPIO port, LCD (1602 or 2004) port, User led and key, on-board power supply, ROM emulation mode to enable the "Auto execution on power-up" feature, can be powered from USB or on-board power supply.


All the details to build it can be found here.
