4f8a45a6ce
Adds #include for ssize_t.
2019-09-18 22:02:59 -04:00

Corrects accidental use of #import.
2019-09-18 21:53:22 -04:00

Enables write support.
2019-09-18 20:18:02 -04:00
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
3002ac8a4a
Adds mapping of READ(8) size 0 to size 256.

...
This once again unblocks Apple HD SC Setup. Progress!
2019-09-16 22:20:42 -04:00
210129c3a1
Updated as per Inside Macintosh IV.
...
Of which I now own a copy.
2019-09-16 21:31:43 -04:00
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
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
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
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
00ce7f8ae0
Takes a first shot at INQUIRY.
2019-09-07 22:04:44 -04:00
6e0e9afe2f
Fixed: to post a message, I want message in, not message out.
2019-09-07 13:35:38 -04:00
cb0d994827
Provides empty data for the unimplemented sectors.
2019-09-07 13:17:53 -04:00
bee782234a
Ensures no state transitions while acknowledge is still asserted.
2019-09-07 13:17:34 -04:00
cbd1a8cf78
Factors out command termination, adds a default implementation of test unit ready.
2019-09-03 22:40:18 -04:00
a4ab0afce3
Takes a shot at completing a full SCSI interaction.
2019-09-03 21:15:30 -04:00
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
318cdb41ea
Adds SCSI bus clocking to the Macintosh, and fixes its internal counting.
2019-09-02 16:03:33 -04:00
2f8e31bc8b
Takes a first bash at implementing the new SCSI::Bus timing infrastructure.
2019-09-02 13:00:01 -04:00
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
25956bd90f
Mildly improves temporary logging.
...
A deckchair shuffle, at best.
2019-08-26 22:35:11 -04:00
1a60ced61b
Starts trying to deal with creating a whole volume from merely a partition.
2019-08-25 23:03:54 -04:00
081316c071
Adds some additional commentary as this takes shape.
2019-08-25 17:46:05 -04:00
eafbc12cc1
Ensures a clean entry into the command phase.
2019-08-25 17:43:14 -04:00

Adds a trivial mass-storage device, for Macintosh HFV volumes.
2019-08-25 15:09:27 -04:00
7d61df238a
Localises #include.
2019-08-25 15:09:04 -04:00
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
ce2e85af8b
Adds missing bus state callouts.
2019-08-22 23:27:00 -04:00

2019-08-21 23:22:58 -04:00
f668e4a54c

...
Not entirely successful. Also gets a bit smarter with `final` on ClockingHint::Sources.
2019-08-15 23:14:40 -04:00
b1f04ed96d
Eliminates the crutch of PlusToo BIN files.
...
Thereby returning the .bin extension to the various consoles.
2019-07-28 16:07:16 -04:00
786b26d23e
Adds an admission of incompleteness.
...
I really need to figure out the 5-and-3 encoding.
2019-07-26 23:23:40 -04:00
d08d8ed22c
Adds a further drift safeguard.
2019-07-26 23:23:01 -04:00
