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
