Thomas Harte
d61f478a39 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.

So that's step one.
 2021-01-31 18:36:29 -05:00

 2020-11-12 18:01:26 -05:00
Thomas Harte
5287c57ee0 Adds the IIgs as a user-selectable machine. 
Albeit that there is no underlying machine yet.

Thomas Harte
8da7806ee9 Liberalises segment parser not necessarily to require a standard epilogue. 
It seems that real disks don't always have them; I guess the boot ROM doesn't require one.
 2020-07-15 22:27:04 -04:00
Thomas Harte

5fd2be3c8e Makes a genuine attempt at five and three decoding. 2020-03-25 20:50:26 -04:00
Thomas Harte
2320b5c1fe Takes some steps towards five-and-three decoding. 
Now I 'just' need to figure out how bits are distributed within the decoded sector. The XORing and data checksum seem the same (?)
 2020-03-25 00:15:31 -04:00
Thomas Harte
e5cbdfc67c It turns out that 5-and-3 disks have a different header prologue. 2020-03-24 21:59:55 -04:00

Thomas Harte
05bcd73f82 Attempts to pull drive ownership into DiskController. 
For the sake of being more intelligent as to drive clocking, hopefully. And, eventually, to support multiple drive selection.
 2020-02-11 21:59:13 -05:00
Thomas Harte
1b27eedf6b Ensure this can definitely never divide by 0. 2020-01-28 23:25:21 -05:00
Thomas Harte
294e09f275 All these 'override's can be 'final's. 
At least for the purpose of being communicative. I doubt there's much to gain in terms of compiler output — the DiskImageHolder can avoid some virtual lookups but nothing else leaps out.

c2bd5be51a This seems to be the proper interpretation of speeds? 2020-01-19 20:42:51 -05:00
Thomas Harte
84f5feab70 Properly flags up overloads. 2020-01-19 20:37:54 -05:00
Thomas Harte
5391a699a4 Adds the ability for a PCMSegment to maintain 'fuzzy' (i.e. random) bits. Implements an LFSR for bit generation. 
I'm not necessarily happy with the idea of just shoving in a [pseudo-]random number generator in rather than emulating the proper process underneath, but for now I throw my arms up.

Thomas Harte

b4befd57a9 Advances to being able to cope with STXs with no special features whatsoever. 
Well, other than perhaps a broken data CRC. Fuzzy bits, timing differences and the stuff between sectors are all currently absent.

909685d87d A drive with no disk is now happy to spin its motor. 
It'll continue to produce index-hole events, which might not be accurate for 5.25" drives. Research to do.

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
