SD-BASIC usage:
All commands must be in uppercase, which is the default at boot.
The 'capslock' is done by pressing Shift and Esc together, and the
cursor will change to a checkerboard pattern.
The above key combination is not available to natural keyboard, so
press ~ instead. Natural keyboard & Paste assume this has been done,
to enable lowercase.
MEMORY MAP
0000-1FFF bios rom
2000-5FFF available for expansion
6000-7FFF static RAM (2K mirrored)
8000-FFFF cart slot
The 16k dynamic RAM holds the BASIC program and the video/gfx etc
but is banked out of view of a BASIC program.
ToDo:
- Joysticks (no info)
