BASIC STARTREK will not load STARTREK.BAS #10

Closed Dietrich-L closed 6 months ago

BASIC STARTREK will start BASIC alright, but not load STARTREK.BAS

Dietrich-L commented 8 months ago

Up to now I was not able to reproduce this error on my test system. The issue will have to wait until my own JC ][ is finished and running.

Also the LOAD command in BASIC is not working.

Error could be reproduced on my JC-][. Basic files are loaded, but are not visible to the basic program. Root cause still under investigation.

Dietrich-L commented 6 months ago

Root cause identified: zeropage cells $FC,$FD are used by ROM routines and need to be buffered in BIOS. Solved with BIOS V0.9
