Hello,
Hello, who knows anything about the "secret" SYS calls in the Commodore
Computers that display messages hidden in the ROMs? I seem to remember
that there is a call on the C=128 that goes something like:
SYS 12800,123,45,6 --or was it-- SYS 12300,123,45,6
I think that one of these calls displays a message from the creaters of the
128 listing their names, and what aspect of the 128 they worked on. Maybe
somebody out there with a 128 could try these SYS's and see if either of them
does anything interesting?
I also seem to recall that on the BASIC 2 Commodore Pet's there what a place
in the Basic ROM, which on some memory maps was labelled "MICROSOFT JOKE".
Does anyone know what this is, OR have an early BASIC 2 Commodore on which
he/she could have a look? I think this would be a 2001 PET we're talking
about.
I think there might have been more cases where messages to the end user were
hidden in the ROM's or system code unknown to Commodore. Appearently the
above SYS call (if I remembered it correctly), uses a series of EOR's to
unencode the message.
Thanks for your interest,
Rob Soukoreff

Does anybody use Easy Script on the C=64? If you do, hit F1, then CTRL/3. Another "undocumented feature" that is rather cute. -Rob Knop rknop@tybalt.caltech.edu
