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.

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.

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.
2020-11-13 22:05:45 -05:00
Thomas Harte
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).

Does a better job of shifting output; takes a new guess at the no-receiver case.

ROM03 at least now reaches "check startup device!"

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.
2020-01-23 22:57:51 -05:00
