Raeto West, "Programming the PET/CBM". It packed with lots of esoteric
information including stuff on non-Commodore disks, assembly fragments to
do useful things, many BASIC examples and more.
This is one I managed to pick up a few days back, I have access to another copy
(if anyone wants to pay postage from Australia & they're o/seas, I can get it
for 'em), at the same time I got 33 Challenging Computer Games for tthe
TRS-80/Apple/Pet by David Chance (they aren't!) & PET/CBM Personal Computer
Guide by C Donahue & J Enger (a "Commodore Authorised" book published by
Hill). This last was a bit of a find, it's so early, it only covers up to the
32k PET 2001 machines ;-), but it contains quite a bit of useful info that I
hadn't picked up elsewhere.
I still program for the PET, but these days, for speed
of developement, I
use VICE and emulate the PET on my SPARCstation. I did finally manage to
port Zork I from the C-64 to the 40-col BASIC 2 PET. Something about
BASIC 4 is clobbering bits of memory, but I don't know where (could be the
DS/DS$ stuff; it s very convoluted).
Is this available anywhere on the net ?
