- Listing files
*.rom.lst                 Source with generated machine code, one for each of
                          the above ROMs

- Patch:
hdbdos-16k.patch          Changes to generate HDB-DOS/16K, applies cleanly to
                          ToolShed GitHub repository as of Feb 18, 2025

TO DO:

- ON ERROR GOTO
- Option to boot in text mode:
  - Different ROM for default in text mode
  - One hot key to swap the text mode at boot
- Make some use of a 6309
- Better instructions


SUMMARY OF CHANGES:

- All CoCo 3 tokens are recognized, so a CoCo 3 BASIC program will not be
  garbled upon loading
- 51x24 and 64x24 text modes in PMODE 4, switchable with WIDTH command
- LOCATE works as expected
- Support for BUTTON function including 2nd joystick button (requires internal
  wiring; testers welcome)
- DIR output uses available screen width
- TIMERL function similar to TIMER but wraps at 2^31 (1 year, 49 days)
- HSET MEM COPY moves BASIC to RAM in 64KB machines; HSET MEM and HRESET MEM
  switch to RAM and ROM respectively
- HPOINT gives you some system information:
  - HPOINT(0) returns the CPU model (6809 or 6309)
  - HPOINT(1) is planned to return whether the 6309 is running in Native Mode.
    (Currently, always returns zero.)
  - HPOINT(2) returns whether BASIC is running from RAM (see HSET MEM)
  - HPOINT(3) returns the address of a useful data area for manipulating the
    new graphics-text mode (cursor blink, shape etc); see new file
    cocoroms/rom16kvars.asm
- BASIC printer output redirected to DriveWire virtual printer (experimental),
  now with a flag in the aforementioned data area to disable redirection,
  still with no BASIC interface to control it
- Accepts binary constants with &B, just like &H and &O
