I verify your last source and equations is based on A_GAL + M'GAL + R"GAL = same firmware as in original DivIDE 57c.

My last modification of your source only add one new feature (reset mapram without power-off ZX)

Logic in original divide is limited with small GAL chips and device is not so good as can be :) Original divide is designed also for tr-dos emulation, but only connection of trdos memory is compatible with original betadisc and return from trdos rom is absolutly incompatible and in your divide this can be fixed (I can add new tr-dos compatible mode, also compatibility with ZX128 rom, compatibility with
ZX128+2A/+3 rom and +3 allram mode).
Idea: add possibility switch DIVIDE 2K11 to "super mode" = all new features can be enable or disable (default = original divide)

About compatibility with ZX128 rom/+2A rom:
- need connect signal /RESET from ZX bus to CPLD
- jumper for +2A compatibility must be connect also to CPLD ( is possible test it via extra software, but reading of jumper state is better)

Idea:
- add reset button to DivIDE 2k11 (very good for use with rubber speccy, TK90X, Timex Computers, Didaktik Gama....)

Yet I can add some features:
- possibility read state of paging port on ZX128/+2A/+3 (7ffd, 1ffd)
- possibility read state of last selected AY register (for possibility make snapshots with correct AY music settings)
- possibility read state or border colour (for correct saving snapshots)
- tr-dos compatibility mode

YERZMYEY/HOOY-PROGRAM:
Hmm. No to jakiego firmware'u będzie potrzebować, żeby chodził TR-DOS??
