David Given	a4002d2617	Fix a few encoder issues; but while 720kB disks work fine in a real machine, ... 1440kB disks don't.	2020-02-14 22:47:15 +01:00
David Given	d25f96dd24	The IBM encoder now works well enough that my USB floppy drive thinks the disk ... is formatted... but has trouble reading sectors above about 1000. Also remember that encoding MFM needs to keep one bit of state at all times.	2020-02-14 00:06:51 +01:00
David Given	ad3a930c6a	Do the boilerplate of the IBM encoder.	2020-02-09 23:56:20 +01:00
