My newest System:
Z80 4Mhz
512Kbyte RAM, (Upgraded from 256Kbyte)
3" Drive with 170Kb/Side
Monochrom Green Monitor with 720x576 Pixel Resolution?
OS: CP/M 1.4 running from Floppydisk
This Machine doesnt have a BIOS, instead it loads minimum Set of Instructions from ULA to RAM,
only enough to read first sector of floppy.

There are lots of Software around, unfortunaly i missing a drive cage to add a 3,5" Floppy Drive.
Why the Images are not in Place 😳
