- Per Mark Pruden, corrected NZCOM user area specification for CP/M 2.2 files.
- Added some DRI files to CP/M 3 that are documented in the CP/M 3 documentation (LIB, LINK, MAC, RMAC, XREF). They are duplicated in CP/M 2.2 image, so this should be reviewed at some point.
- Added XREF to CP/M 2 disk image for consistency with CP/M 3.
- Updated Catalog.md per Mark Pruden to eliminate obsolete column from table.
* Moved DIOMED_MID variable - so it would be overwritten at start of main Calculation
* Removed code in SYS_GETDIOMED1A - since SYS_GETDIOMED6A did exactly this anyway
* Removed code that set MID_HD - since it would now already be set.
The delay function is delegated to the on-chip ROM.
The on-chip ROM uses a programmable reload timer that is calibrated for a range of
CPU frequencies and wait states.
The Z280 Interrupt Vector Table must be gin on a 4K boundary. Recent HBIOS changes caused it's location to result in a very large slack space. This update moves the Z280 IVT to a more memory efficient location.
- Support HEATH MSX Graphics card in HBIOS
- Support HEATH MSX Graphics card in TUNE app
- Startup HEATH at 8MHz to ensure hardware compatibility/detection
- Added RCEZ80 platform option to Build.ps1
- Added EZ80 config settings to MASTER config (required to get build to work for some situations)
- Modified a .EQU in cfg_RCEZ80.asm to a .SET. After adding config setting to MASTER config, the .EQU was causing a redefinition error.
- I have temporarily removed some "TRANSLATE" lines in ez80uart.asm. They were attempting to place a value greater that 0xFFFF in a register and generated an assembly error.
- Modified a few JR instructions in hbios.asm to JP due to out-of-range errors.
- Modified std.asm to "nest" a conditional. The Windows assembler does not ignore the remainder of a complex conditional when it should.
- Modified tms.asm to replace the PRTS macro with alternative lines. The Windows assembler cannot handle a string longer than about 8 characters in a macro argument.
- Added the TIMER utility to the ROM disk. Not sure what happened there. It was included in the Windows build, but not the Linux build. There is room for it, so I added it to the Linux build to get a binary exact build compare.
Changes to support a modified Prolog Keypad and LCD driver card - Heavily inspired by the lcd.asm module, but separated out to allow for future keyboard support.
