> I'm planning to make a fantasy computer myself (basing it off the z80)
This is so much fun, I did this last year, although initially it only ran inside Unreal Engine. Later on I did a "native" port to Linux. It can run CP/M 2.x and Wordstar (https://i.imgur.com/rIY1he8.png), it had a telnet+VT100+zmodem client for accessing BBS's (https://i.imgur.com/VszSPkB.png), and I even added a graphics mode later on (https://i.imgur.com/t3kreQM.png).
I'm working on a 68000 based one now as well. It's a really great learning experience.
