[Coco] "Reading" non-readable bytes with PEEK vs ZBUG

Roger,

You are assuming that all hardware and all implementations of LOADM will produce a '1' in bit 6 of an MMU register. If you are comfortable with that assumption, fine. I would certainly not rely on that for anyhing intended for public release.

If you insert the following 84 bytes into the beginning of your bin file, you wouldn't have to worry about any of this.

00 00 41 01 DA CC 7E 3B B7 01 6A F7 01 06 8D 23
34 02 8D 2B 1F 02 8D 27 1F 01 A6 E0 27 0B 9F 9D
BD A4 2D BD AD 33 7E AC 73 8D 08 A7 80 31 3F 26
F8 20 DB BD A1 76 0D 70 27 0B C6 2E 7E AC 46 8D
00 8D F0 1E 89 39 00 00 03 01 06 7E 01 DA 00 00
01 01 6A 3F
