I am reading Programming the Z80 by Rodnay Zaks to refresh my knowledge of Z80 assembly. I usually develop and compile the code on my laptop, but this time I wanted to experience writing and testing the code on my RC2014 computer running CP/M. The assembler that ships with CP/M uses 8080 instructions, so instead I am using Z80ASM by SLR Systems. I edit the files using ZDE 1.6. The book provides sample code like this for 8-bit addition,
Journey Back to the 8-Bit Era: Welcome to My Lab! Hello, fellow retro enthusiasts! Welcome you to my digital sanctuary, the 8-Bit Labs. This is more than just a blog; it’s a personal journey back to the time when 8-bit computers ruled the world. If you, like me, have a passion for retro computers, 6502 and Z80-based home-built systems, Game Boy hardware and programming, and RC2014 computers, you’ve come to the right place! From a young age, I’ve been fascinated by the technological wonders of the 8-bit era. The 6502 and Z80 microprocessors, the powerful hearts that pumped life into...
