I wrote a Z80 assembly program
for my RC2014 Zed computer.
I wanted to get a complete CP/M experience,
so I used the CP/M 2.2 ASM assembler, LOAD relocator,
and the DDT debugger.
I did cheat a little. Although I used the vintage RED editor for some text input, I also wrote some on my Linux laptop, and transferred to the RC2014 Zed via XMODEM.
I’m a little happier with my wordle-solving regular expression today.
This is something:
The Go programming language has a unique, built-in concurrency model that can make some processing much easier.
Have one goroutine do some (probably recursive) work. It puts results on a channel. The main goroutine reads results from the channel and possibly does some filtering on those results, like output unique values.
I built a Z80-based RC2014 Zed computer from a kit.
It’s often said that DEC operating systems influenced the design of the CP/M microcomputer OS. Let’s examine that assertion by looking at how a process was laid out in memory.
