This appears to be sufficient for the Electron to _read_ SCSI.
...
So that's step one.

Many more warnings to iron out, however.

Eliminates static where constexpra aren't class members; adds some if constexprs for clarity.

962275c22a
Removes clock for NCR 5380.
...
It doesn't have one in real life, and now can live off the time counting that occurs on the SCSI bus.

This once again unblocks Apple HD SC Setup. Progress!

Updated as per Inside Macintosh IV.
...
Of which I now own a copy.
2019-09-16 21:31:43 -04:00
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.
2019-09-12 21:58:09 -04:00
Thomas Harte
87e8dade2f
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.

Thomas Harte
6fc5b4e825
Simplifies INQUIRY for future targets; implements enough of SENSE MODE to advance.
...
The HD SC setup utility is now looking to read buffer.

Takes a first shot at INQUIRY.

Thomas Harte
1c7e0f3c9d
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.

Adds SCSI bus clocking to the Macintosh, and fixes its internal counting.

Takes a first bash at implementing the new SCSI::Bus timing infrastructure.
2019-09-02 13:00:01 -04:00
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.
2019-08-31 21:44:22 -04:00
Thomas Harte

Mildly improves temporary logging.

A deckchair shuffle, at best.

Thomas Harte
c86db12f1c
Starts implementing DMA support on the 5380.
...
The Macintosh doesn't actually use the DMA signals, but uses pseudo-DMA mode so they nevertheless need to be appropriate.
