I have an ATR8000 Z80 based CP/M system with two 8" floppy drives (plus a 5.25" floppy drive). I recently took it out of storage to pull some files from a set of 8" floppy disks. This system is dual boot, as it has an 8088 "coprocessor" and 512MB ram add-on that allows me to also run MSDOS 2.11. (If running CP/M, I can use the 512MB of ram as a ram disk). I transfer files to DOS compatible 5.25" floppy disks and from there transfer the files to a PC. I don't have the space to set it up permanently, and I was planning to give it away, but a friend is going to buy it.
Decades ago, I worked with a Pertec PCC 2000 8085 based CP/M system, that included two half height 8" floppy drives and also a 6MB hard drive. It was all in one case, that included the monitor, keyboard, serial port and printer port, and port that worked with those old 14 inch single platter hard drives.
I have seen a few of the Radio Shack TRS 80 CP/M systems, Altair 8800's, and some S100 CP/M systems back in the "olden" days.
