Basic sketch for state snapshots: an extra field on Target.
...
I think it doesn't make sense for states to own a target as that complicates the concept of Media. Plus they're distinct because it makes sense to have only one per Target. Let's see how this pans out.

A drive with no disk is now happy to spin its motor.

Thomas Harte
934901447a
Adds a temporary version of block access writing.
...
Whatever I'm doing, it's still not correct. The Macintosh ostensibly appears to 0-fill the direct-access device, then reads a sector back and hangs.
2019-09-15 22:06:45 -04:00
Thomas Harte
c849188016
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.

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.

Thomas Harte
310c722cc0
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.
