Thomas Harte
5287c57ee0
Adds the IIgs as a user-selectable machine.

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.

Adds format and write to the SCSI target.
...
Now I think I need to switch back to the 5380 to ensure proper DMA mode interactions when writing.

Implements READ BUFFER to do, you know, *something*. Plus READ CAPACITY.
...
The HD SC utility now offers up drive 6 for formatting. That's progress.

Simplifies INQUIRY for future targets; implements enough of SENSE MODE to advance.
...
The HD SC setup utility is now looking to read buffer.

Fixed: to post a message, I want message in, not message out.

Fixes control line modification by the 5380 and SCSI target command chaining.
...
So now I'm back to trying to guess how a SCSI command terminates re: the relative meanings of a message phase and a status phase.

Starts a transition to bus-level knowledge of SCSI-specific bus timing thresholds.
...
The idea being that bus attachees need not all count time for themselves. They can be very plain finite state machines.
New semantics are not yet implemented within the Bus. The plan is to do that, remove the internal counting of time within the NCR, then adjust the Target to be more explicitly stateful.

Mildly improves temporary logging.
...
A deckchair shuffle, at best.
