128a1da626 Enables write support. 2019-09-18 20:18:02 -04:00
Thomas Harte
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.
 2019-09-18 20:17:47 -04:00
Thomas Harte
3002ac8a4a Adds mapping of READ(8) size 0 to size 256. 2019-09-17 21:59:32 -04:00

Thomas Harte
2ce1f0a3b1 Implements multi-sector read/write.

 2019-09-16 22:20:42 -04:00
Thomas Harte
210129c3a1 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.
 2019-09-11 21:52:02 -04:00
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.
 2019-09-08 21:59:56 -04:00

Thomas Harte
cb0d994827 Provides empty data for the unimplemented sectors. 2019-09-07 13:17:53 -04:00

Thomas Harte
a4ab0afce3 Takes a shot at completing a full SCSI interaction. 2019-09-03 21:15:30 -04:00
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.
 2019-09-02 23:14:37 -04:00
Thomas Harte
318cdb41ea Adds SCSI bus clocking to the Macintosh, and fixes its internal counting. 2019-09-02 16:03:33 -04:00
Thomas Harte
2f8e31bc8b 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
25956bd90f 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.
 2019-08-24 22:47:11 -04:00
Thomas Harte

7b7beb13a3 Eliminates the fiction of setting and getting registers. 
The Disk II seems lower level than that; it will read the data bus whenever it likes, it is the programmer's responsibility to keep up with that. It also reserves the right not to load the bus regardless of whether it receives a read or write access.
