This format uses 4 types of file...
- SEUCK LOADER 2
- SEUCK HEADER FILE
- SEUCK DATA FILE
- SEUCK TRIGGER FILE
The CBM files contain a loader that is set to load just ONE file to address $000A, the file contains LOADER 2 and is formatted as follows...
SEUCK LOADER 2...
Handles loading of SEUCK HEADER,DATA and TRIGGER files.
Load address = $000A, File Size = 196 bytes.
Pilot : $E3 (*10)
Sync : $D5
196 bytes data
Checksum (0 XOR all data bytes)
SEUCK HEADER FILE...
Load address = $0002, File Size = 2 bytes.
Only 1 header file exists on the tape, it provides a single load address for all following
DATA files to load from.
Pilot : $E3 (*10)
Sync : $D5
ID Byte : Anything but $CC or $AA, the value $BB is found on the SEUCK tape)
2 bytes : Load address (LSBF)
SEUCK DATA FILE...
Pilot : $E3 (*10)
Sync : $D5
ID Byte : $CC
1 byte : Data length (n)
n bytes : Data
1 byte : Checksum (0 XOR all data bytes).
SEUCK TRIGGER FILE...
Provides a single execution address that will run the program. for the SEUCK it is $0810.
Pilot : $E3 (*10)
Sync : $D5
ID Byte : $AA
2 bytes : Execution Address ($10,$08)
