A full implementation of UCSD p-System IV.0 for RomWBW. Derived from the official Z80 Adaptable p-System.
My first real programming was on this system. So many memories...
- Minimal support for QP/M by adding a disk image.
- Disk image is not included in combo image, it must be added separately.
- Disk image boots into CP/M 2.2. You must run QINSTALL to configure it and make the disk boot into QP/M.
- It is critical to review the ReadMe.txt file -- default QP/M configuration conflicts with RomWBW use of Page Zero.
- Added some stack space to SYSGEN. It was failing when run with extra CBIOS debugging enabled.
- Cleanup of diskdefs file.
- Updated SIMH executable.
- Add hardware detect and initialization code to Centronics driver.
- Fix .gitignore to reflect subdirectory name changes under Tools/cpm/.
- Bump version number in TUNE to reflect Dan's changes.
- Detect Centronics hardware in MBC configuration by default.
I had updated SLR180. The newer version switched the default file extension it looks for from .180 to .z80. Changed filenames and build/make files to adjust to this.
- Improved ASSIGN operation under CP/M 3 to better handle BIOS function invocations
- Added 2PIOTST for testing the DUALPIO MBC board
- Increased default RAM drive size for ZRC
- Fixed the ROM VERIFY functionality on Z280. It was indicating errors incorrectly.
- Revised the way that ZZRCC is built to remove a bunch of complexity that was causing issues. An implication of this is that ZZRCC now treats the data loaded from the CF Card as a ROM disk instead of a RAM disk.
- Updated the assemblers to handle some more Z280 instructions used in HBIOS.
- When building ZZRCC, checks have been added to ensure the ROM image is exactly 256K. The build defaults to 512K and that causes the ZZRCC disk image to be corrupted. This will stop the build if the user fails to specify a 256K ROM size.
- Add proper Build and Makefile files in Source/Doc directory
- Switch preprocessing from pp to m4 which is more supportable across platforms
- Building of documentation is still done manually as needed, but it is now easy to do under either Windows or Linux using provided files
- Rename Dev.txt to ReadMe.txt for consistency
- Update Dev app Makefile to not copy the internal ReadMe file to the final output
- Remove obsolete constants in BPBIOS
- Minor patches to zx and cpmtools to workaround an odd behavior in Windows Subsystem for Linux that was causing output to fail binary comparisons.
Lars Nelson has contributed 3 new apps.
- XSUB1 is an improved version of DRI XSUB that allows it to be removed from memory using RMXSUB1
- EX is an early variant of the ZEX batch file processor, but EX runs on ZSDOS (does not require later versions of ZCPR).
- SCOPY is a visual file copy utility which requires ZCPR 3+. It is included on the ZPM disk image.
