8d4a96683a
Reduces output noise.
2019-09-18 21:41:29 -04:00
f53411a319
Removes local NDEBUG.
2019-09-18 21:35:26 -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
2f6c366668
Makes a concerted effort at properly wrapping a hard disk image.
2019-09-17 21:30:04 -04:00
2ce1f0a3b1
Implements multi-sector read/write.
...
This once again unblocks Apple HD SC Setup. Progress!
2019-09-16 22:20:42 -04:00
960b289e70
Edges closer towards proper DMA operation.
...
Specifically: differentiates the three kinds of DMA operation. Still doesn't act correctly with regard to DACK though, and leaves the bus instantaneously improperly formed. Which I'm tempted to try to fix on the target side by properly obeying delays.
2019-09-15 15:03:06 -04:00
243e40cd79
Adds signalling of DACK.
2019-09-14 13:48:33 -04:00
64dad35026
Decreases logging, at least temporarily.
2019-09-03 22:40:32 -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
ca08716c52
Introduces real hard disk images to the nascent world of SCSI.
2019-08-25 17:03:41 -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
e3d9254555
Implements phase-match bit.
...
Seemingly causing the command phase to proceed.
2019-08-18 23:15:54 -04:00
955e909e61
Attempts to nudge the command phase further towards functioning.
2019-08-18 22:39:27 -04:00
0e0c789b02
Starts attempting to introduce a direct access device.
...
Without having access to the SCSI-1 standard, a lot of this is guesswork.
2019-08-17 23:43:42 -04:00
7e001c1d03
Corrects data line loading.
...
Also adds some extra temporary logging. Outstanding question: why is ATN not being signalled? Is SEL enough?
2019-08-17 21:30:59 -04:00
9047932b81
Corrected basic error. Arbitration now seems to succeed.
...
This is seemingly followed by a pattern of signalling BUSY+SEL followed by just SEL with the various other potential device IDs in turn. To which nothing ever responds as currently implemented.
2019-08-15 23:28:30 -04:00
f668e4a54c
Makes an attempt at getting the 5380 past arbitration.
...
Not entirely successful. Also gets a bit smarter with `final` on ClockingHint::Sources.
2019-08-15 23:14:40 -04:00
ce1c96d68c
Starts thinking out the mechanics of emulating a SCSI-1 bus.

Adjusts NCR address decoding to produce a more plausible initial interaction.
2019-08-11 22:43:25 -04:00
a90a74a512
Stubs in just enough of the 5380 to get a Mac Plus too boot.
2019-08-11 20:55:20 -04:00
949c1e1668
Adds an empty shell for what will be my 5380 implementation.
