the physical disk supports two logical disks. Added a logical disk number
which returns 0 when there are no logical disks or the specific logical
disk number if they exist. Currently, only UniDosFormatDisk does this.
In the future, Pascal disk may support this and possibly ProDOS disks
that have sections set aside (ie, a Pascal partition) - if they exist in the
real world.
800K disk images; split out isUniDosDisk from isDosDisk; changed
sizing of image in memory just use the File as that is better than the
dumb logic that was originally in place.
writeFileEntry. This changed the relationship to the ProDOS disk
image - now the ProDOS entries contain the disk, block, and
location that they exist at instead of a raw array of bytes.
reason, some DOS 3.3 images do not set the VTOC byte 0x03 to be
3 - this is the DOS release number which created the disk. The images
I have just have a zero (0) in this position.
more information gets written to disk as part of the format process.
In particular, the &CAT command will crash as the catalog routine is
apparantly loaded in from disk (T1,S9 in DOS parlance) and then
executed.
(2) needed to clear the keyboard (otherwise the keypress was still
valid when the next disk was booted). Also needed to reduce program
by a few more bytes. By changing the rotate routine and changing
the wording in the message, this code is now only 254 bytes.
