01cf7462d5 Disk II: Don't overwrite data bus when not asked to
Return DidNotLoad rather than 0xff from read_address on odd-numbered
addresses so that the data bus is not overwritten with 0xff on those
accesses.

b91a791e01 Fix Disk II sense-write-protect clocking preference
Ensure we're actually in the sense-write-protect loop before deciding
that we don't need to process anymore.

Handle C, E, F operations in Disk II state machine
This shouldn't matter since these operations are not requested by the
state machine but this is what those operations should do according to
Understanding the Apple II, Table 9.3, page 9-15.

4a42de4f18 Attempts to add 5.25" drive support to the IIgs.
I want to try some classic software.

cddd72876f Flips meaning of ejected bit, to please the IIgs. 2020-11-18 17:20:48 -05:00

37815a982a Much logging later, corrects 7Mhz IWM windows.
Confirmed by mathematics — the new ones are seven-eighths the length of the established 8Mhz windows — and with reference to suitable Apple documentation.

b0fc2f6ecf Amps up logging.
Current suspicion is that the IIgs isn't getting a clean byte stream, never mind whether my assumption of exactly-Mac-style GCR holds (which it probably doesn't).

72884c3ead Does a better job of shifting output; takes a new guess at the no-receiver case.
ROM03 at least now reaches "check startup device!"

31c6faf3c8 Adds a bunch of consts. 2020-05-09 21:23:52 -04:00
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.

f668e4a54c Makes an attempt at getting the 5380 past arbitration.
Not entirely successful. Also gets a bit smarter with `final` on ClockingHint::Sources.

9bbccd89d3 Adds an extended rationale for current implementation.
Also strips some cruft of prior guesses.

2aa308efdd Tweaks magic formulas.
The computer now at least seeks outward, until this attempt at drive speed calculation fails.
