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.

Sounds cool -- where is it on the store? I found the 2364 adapters, but
I'm not seeing anything for 6540s...
Thanks!

I took them out pending the new shipment of boards, but I put them back
in with qty 1 if you're interested.
