David, I cannot help you in the documentation arena, but if you
have access to TeleDisk and a PC with 5.25" floppy drive -
preferably 360k - I will email you any or all of the following
disk images:
Research Machines Limited
Name Format Description
RML14B31 SSSD CP/M 1.4B (31K) system disk for 380Z
RML14B56 SSSD CP/M 1.4B (56K) system disk for 380Z
RML22C31 SSSD CP/M 2.2C (31K) system disk for 380Z
RML22C3R SSSD CP/M 2.2C (31K) system disk for 380Z (reformatted)
RML22C56 SSSD CP/M 2.2C (56K) system disk for 380Z
Or, if TeleDisk is not an option, send me private email and we can
work something out.
