I don't know if it's possible, but anyway, that PET was powered down for probably 15 years and I've found it on a dumpster, so it's a good start to get it working fine for hours. > > My C2N232 might be one more option, if you can find one second-hand. > However, it relies on RS-232, which nowadays is mostly available via an > unreliable USB converter.

I have many computers (PCs even) with RS-232, so it wouldn't be a problem. The real problem is it uses an old micro AT90S2313. I have tons of ATtiny2313 instead, I've found a firmware for the new microcontroller but I'm not sure about the schematic getting modified or not. Sorry but the documentation about C2N232 could be a bit better maybe :) I've ended in making a PC64 cable that I use with cbmlink linux software and it works great on VIC-20, C64, SX64 (no tape port there) and the PET too. However, I still need a "local" mass-memory to allow the PET to run without the PC cable connected.
