This is a stretch, but I figured I'd ask: anyone
have any spare
6540-series PET ROMs lying around? After diagnosing a number of other
failures, Ialmost have my (very beat up) chicklet-keyboard PET
working, but it looks like the -026 ROM (at F800-FFFF) has gone south
-- it has a few corrupted bits here and there. It looks like adapters
to fit standard 2716s are available to build, but before I invest time
and/or money in one of those I thought I'd ask around.
Thanks as always,
Josh
I have a 6540 adapter that converts 2764-27512 to 6540 pinout in the
store. I have assembled units under manufacture, but they have not
arrived yet. Still, I have a couple bare PCBs here from the test run I
can solder up for you if interested.
