Posted on 04/01/2022 by hanso

Design and text by Wichit Sirichote. The kit is available for sale, kit or assembled. Wichit picked the Z80 CPU and designed the microcomputer kit with HEX keys and 7-segment LED displays, and wrote the monitor program.The version I have is an older (slower) version with a monitor (source in User manual) close to the the Microprofessor 1b. The current one has a SDCC compiler generated monitor program.
