------------------------------------------------------------ Technology/Z80/Space, (sdf.org), 11/26/2018 ------------------------------------------------------------ Got the z80 SBC going again on Saturday night. At first it wouldn't post properly (grant searle's ROM), but I re-seated the CF expansion board and that seemed to help. CP/M came up and I was able to explore the drives without trouble. While it was down, I had setup an emulated environment for CP/M on my linux box. It works very well, and transfering programs and files in/out is simple. You can control emulation speed, to keep it closer to hardware, but I have found this to be buggy/inconsistent. In any case, it does work, and it emulates a z80, so it's suitable for compiling (tried it with something, I think it was just an mbasic program.) Sometimes I wish I had unlimited space. I know that I'd have unlimited junk if that were the case, so I count my blessings, but I can't help but want more space for my projects and hobbies. Right now, the z80 lives on a desk in the basement. I'm remodelling down there, and don't have the heat piped in; because of the ground it has been pretty constant near 60F, but that's a bit cool for my taste. Maybe I'll drop a space heater by the desk to see if that helps. I read an article recently about a sci-fi writer that writes in Wordstar (can't recall if it was under DOS or CP/M.) WS is a nice program (I have two versions installed, both work well with my terminal, but have different advantages for me.) I don't know if I quite trust my little computer enough to write a book on it though; I think I'd have to have a good backup solution going. My system is installed on CF, and I can mount it with the cpmtools on my linux box, and copy files directly off/on. Unfortunately, I soldered the CF connector myself, and the pitch on the connectors is very small; I don't trust it much, and I don't like removing the card. In short, I don't want to have to take it out daily to back things up... I could just write stuff on my main computer, or some other device, but I really enjoy the z80 SBC and terminal. I do have two serial ports, but I haven't really had much success with the second serial port yet (it's been odd...) I think it might be time to reach out to Grant Searle and ask him about programming that second serial port in mbasic. Or, maybe I can find some resources. I'd like to write a little file transfer program. I've had poor luck getting the ones I've found for CP/M working right; maybe if I have something really barebones, I can get it going.
