Hello,
first I would like to greet you all! I am a newbe here. My name is
Ruediger Schuldes and I am a german collector of Commodore items. The
address of my Website is http://www.cbmmanuals1.de. I hope you answer me
despite my bad English.
But now to my problem. I have a SuperPET, which hangs up each time I try
to load one of the Waterloo-languages. Even sometimes it happens that
the screen is blanking and a whistling sound comes out of the computer.
It is one the "3-deckered" SuperPETs with 4 switches. As additional ROMs
are inserted "SM-KIT B" ($9000) and "PAICS" ($A000).
The 32kB main memory of the computer (8032) is perfectly working,
likewise the 4kB additional memory, which one can switch on at $9000.
The positions of the switches are:
UD11 off
UD12 RAM
R/W
6809
What could be wrong or broken? I am very grateful for each assistance!
Best regards
Ruediger
