e9164d9872 Very minor changes to make the code simpler 2018-02-16 00:19:14 -06:00

058b45e7d1 Use 9-bit rotation, not 8-bit 2018-02-15 19:32:01 -06:00

067c0cea2f Also check the N flag (i.e. set it to zero) 2018-02-15 13:01:58 -06:00
Peter Evans
e415b3e490 We should check only the first byte for zero
We need to accept values for result that are greater than a byte so that
we can determine if carry is set, but this causes an issue when an app
uses addition to force an overflow that would set the zero bit. Masking
result for only the LSB fixes that problem.

fe70cd1f71 Remove debugging, use ENC_ETRACK for sector pos max
Also, there's no need for a while statement; we can just reset to zero.

7224698cd7 This should be EOR, not ADC
I might as well fix the bad opcode here, too!

9a5c94bbbb The 49 opcode is EOR, not ADC.
Excuse me, I just need to scream now.

AHHHHHHHHHHHHHHHHHHHHHHHHHHHHHH

Thank you for your indulgence. Please carry on.

64b9cbefcb Several changes to phase and writes
1. The phaser algorithm was reworked, and it should be more accurate in
choosing when to step forward or backward.
2. Writes should be committed when the latch has bit 7 high. This hasn't
actually been a problem yet, since other things are broken! But we might
as well fix it now that we've seen it.

ba387c004f We should be dividing, not using modulus 2018-02-11 20:36:41 -06:00

3e2d8acacf The same track/sector method works for all images
Particularly so as the data segment is now the 6-and-2 encoded form,
which we either encode from DOS 3.3/ProDOS, or use literally from NIB
files.

a84b4c12e9 Treat pause and disasm as toggle functions
This allows us to remove the resume and disasm_off functions. (The
disasm_on function is simply renamed to disasm.)
