Hi all,
For the PET aficionados here, wanted to let you know that I recently did a redesign of the PETdisk MAX device to use a new, more capable microcontroller (ESP32 vs ATMega1284) and I'm looking for a few people who would like to help test out the new version with some PETs.
The primary motivation for the redesign was lack of availability for the original controller - currently the ATMega1284 and seems like most other atmel mcus are generally impossible to get right now, at least in surface mount form. The ESP32 has the big advantage of being widely available, as well as having wifi capability and generally being a fast microcontroller. The firmware code, thankfully, was already mostly hardware agnostic with hardware access being in only a couple of source files, so going forward it will be reasonable to support both architectures so both v1 and v2 get regular firmware updates.
I will have a small number of these available for testers, probably about 5 of them. Ideally if you have any other IEEE-488 devices (disk drives, printers, etc) for the PET, would be nice to verify that these still work with the passthrough capability on the device, as I don't have any around for real testing.
If you are interested please let me know - if shipping to you is not much I can just cover it, if not I would probably ask you to pay for shipping.
Thanks everyone. Will post some pictures of the new boards once they arrive.
