概 要カセットのセーブ、ロードが動作しなくなった。
詳 細Cassettes used to work, and I still have 2 test tapes. But they can no longer be loaded as they are not recognised.

When saving a tape, the result is garbage and can't be loaded back.
再現手順Start alphatro and make sure the FDD Interface is OFF.

Microsoft Basic will start up.

Create a small program, for example:
10 PRINT "ALPHATRO"

Mount a new tape and hit record.
CSAVE"x"

The tape will be saved.

Now restart the system and try to CLOAD the tape. It will be ignored.

The tape format is supposed to be 1200 baud KCS, but it is now something else entirely.

Most KCS tapes can be verified with the Super-80, with the header consisting of a string of D3 bytes followed by the name in quotes from the CSAVE command, and then followed by the program (tokenised). The tape now is just nonsense bytes.
