- 1. The best way to find out about CPXs is to buy DocSupport II. Not that I've
- managed to write one... Anyone have CPX code for Lattice C?
-
- 2. TOS by default clears all unallocated RAM before running a new program so that
- it can guarentee(sp!) that any spare memory is all zero's
- That's OK on a 520, but clearing 4Mb of memory on an 8MHz 68000 is painful to say
- the least.
- PinHead stops TOS clearing all that space, and is compatible with MOST software.
- The Fastload bit with is the 28 byte header at the start of any TOS/PRG program
- is Atari's way of doing the same thing. Any program with this bit set won't have
- its memory cleared by TOS 1.4+.
-
- 3. Dunno!
