VIC Graphics And Super Expander
I'd like to share something with other readers who have VIC Super Expanders. We find that it interferes with some programs written for the unexpanded VIC, especially ones with custom characters. When I find such a program, or am told to "remove all expansion devices" for a certain program, I add the following as the first line in the program (or enter it in the direct mode before RUNning the program), and the program runs fine with the Super Expander left in. (In the case of two-part programs, insert the line in the second part.)
POKE51,30: POKE55,0: POKE52,30: POKE56,30: POKE646,6
This has worked on every program I've encountered so far, and what's nice about it is that you are left with the additional memory as well.
