The AR cart worked quite flaky (failed to start sometimes, freeze button crashed the C64) as well as many demos. I also upgraded the AR to 5.1a.
So I figured that the EPROM based PLA was causing that.
Some weeks later the realPLA became "available", the shop owner who sells these had serious health problems since the last year.
I fucking waited more than a month for this.

Mathematica was the last demo I tried with the EPROM PLA, unsuccessfully as it crashed after minutes. With the realPLA it ran till the end.

The freeze button still doesn't work and the fastloader often fails to start either (?OVERFLOW ERROR IN 0) which wasn't really the case with the EPROM PLA.
I guess some little capacitor which had been installed depending on the used PLA chip causes that, I will remove it and see if it works.

You guessed the age of that EPROM burner precisely.
It says 1985 on the PCB and most datecodes of the chips are from mid 1986.
