... which still declines to boot.
2020-11-12 18:01:26 -05:00
Thomas Harte
5287c57ee0
Adds the IIgs as a user-selectable machine.

Thomas Harte
2320b5c1fe
Takes some steps towards five-and-three decoding.

Thomas Harte
05bcd73f82
Attempts to pull drive ownership into DiskController.

For the sake of being more intelligent as to drive clocking, hopefully. And, eventually, to support multiple drive selection.
2020-02-11 21:59:13 -05:00
Thomas Harte
1b27eedf6b
Ensure this can definitely never divide by 0.
2020-01-28 23:25:21 -05:00
Thomas Harte
294e09f275
All these 'override's can be 'final's.
...
At least for the purpose of being communicative. I doubt there's much to gain in terms of compiler output — the DiskImageHolder can avoid some virtual lookups but nothing else leaps out.

5391a699a4
Adds the ability for a PCMSegment to maintain 'fuzzy' (i.e. random) bits. Implements an LFSR for bit generation.
...
I'm not necessarily happy with the idea of just shoving in a [pseudo-]random number generator in rather than emulating the proper process underneath, but for now I throw my arms up.
