I believe it was done this way to make it easier for users to transition
from CP/M 3 to ZPM3.
## QPM
QPM is another OS providing compatibility with and enhancements
to CP/M 2.2. It is provided as bootable disk images for RomWBW.
The following documentation files from the original QPM distribution
are included in the RomWBW Doc directory:
- QP/M 2.7 Features and Facilities (qcp27.pdf)
- QP/M 2.7 Interface Guide (qdos27.pdf)
- QP/M 2.7 Installation Guide and Supplements (qpm27.pdf)
Refer to the ReadMe.txt file in Source/Images/d_qpm for more details
regarding the RomWBW adaptation and customizations.
### Notes
- QPM is not available as source. This implementation was based
on the QPM binary distribution and has been minimally customized
for RomWBW.
- QINSTALL is used to customize QPM. It is included on the
disk image. You should review the notes in the ReadMe.txt
file in Source/Image/d_qpm before making changes.
## UCSD p-System
This is a full implementation of the UCSD p-System IV.0 for Z80
running under RomWBW. Unlike the OSes above, p-System uses it's
own unique filesystem and is not interoperable with other OSes.
It was derived from the p-System Adaptable Z80 System. Unlike
some other distributions, this implements a native p-System
Z80 BIOS, it does not rely on a CP/M BIOS layer.
The p-System is provided on a hard disk image file called
psys.img. This must be copied to it's own dedicated hard
disk media (CF Card, SD Card, etc.). It is booted by
selecting slices 0 of the corresponding hard disk unit at
the RomWBW Boot Loader prompt.
The p-System Users Manual is included in the Doc directory
of the distribution as "UCSD p-System Users Manual.pdf".
Refer to the ReadMe.txt file in Source/pSys for more details.
### Notes
- There is no floppy support at this time.
- The hard disk image contains 6 p-System slices which are
assigned to p-System unit numbers 4, 5, 9, 10, 11 which
is standard for p-System. Slices 0-5 are assigned
sequentially to these p-System unit numbers and it is
not possible to reassign them.
- p-System relies heavily on the use of a full screen
terminal. This implementation has been setup to expect
an ANSI or DEC VT-100 terminal or emulator. The screen
output will be garbled if no such terminal or emulator
is used for console output.
- There is no straightforward mechanism to move files in
and out of p-System. However, the .vol files in Source/pSys
can be read and modified by CiderPress. CiderPress is able
to add and remove individual files.
