I'm interested to find reliable way to identify PC SCP disk images and what type these are. (I don't care about non-IBM disk images at the moment.)
Looking at the SCP format description this should be possible by checking Byte 4. But when I look at my SCP images the value is not even close to what I expect and I can see no way to match it up to the documentation...
Here some samples I created at different times using the SuperCard Pro Software. The last sample was created just now after double checking that as format IBM 1.44 had been selected:
0x45 would map to DISK CLASS TANDY and an undefined SUB.CLASS. Am I missing something or is the documentation really wrong here?!?
Unrelated but also noteworthy, there is a typo in the tapes section:
In context it's more or less obvious that this should be tape_MFM = 0x02

Code:
