#882 - By Marley W. Watkins. State of the art in computer assisted reading instruction... Covers reading skills typically taught in grades K-3. Pairs picture and typed word with spoken word if the cassette interface and tape are purchased separately (sorry, I do not have those).
Disk structure
This is a modified DOS 3.3 16-sec disk. No extra track.
There is a change of the epilog markers of the address and data fields:
- D5AA96 FFFFFF (std is DEAAEB)
- D5AAAD FFFFFF (std is DEAAEB)
- Sync nibbles are changed from FF to AB
- First nibble in translation table is changed from 96 to AA
- Nibble check in $BB00
How to copy
Boot the disk, when at the main menu, enter the monitor and type
Code: |
10/B700<00/B700.BFFFM
|
Remove the disk, boot my copy disk and
Code: |
Launch advanced demuffin
Enter monitor
B930:18 60 EA
B98B: 18 60 EA
Press control-Y
Copy T0/S0 to T0/SA
Enter monitor
00/B700<10/B700.BFFFM
Press control-Y
Copy T0/SB to T22/SF
|
Your unbootable copy is ready.
How to normalize
Boot my copy disk and
Code: |
Launch Disk Fixer v4
T0/S0/4B: FE BB -> FD 08 // skip nibble check
T0/S2/3E: AB -> FF // std 10-bit sync nibble
T0/S2/4B: AB -> FF // std 10-bit sync nibble
T0/S3/35: FF -> DE // std epilog marker
T0/S3/3F: FF -> AA // std epilog marker
T0/S3/91: FF -> DE // std epilog marker
T0/S3/9B: FF -> AA // std epilog marker
T0/S4/29: AA -> 96 // normalize nibble table
T0/S4/69: A9 -> 60 // bypass change of markers
T0/S6/60: FE -> FF // std 10-bit sync nibble
