Panana 1.0

September 25th, 2014

Panana 1.0, the first version of the Arduino-based PC -> Panasonic JR-200 transfer cable is now finished and published. You’ll find all the necessary bits like software and some instructions on the Panasonic page, as usual. Here’s the schematic and the final cased contraption:

 

There would be sooo much to add, like two-way transfer, support for BASIC files, a card reader and extra RAM, but let’s see if I ever get to that. At the moment the kludge already supports what I most want to do with it: test my own software. The transfer speed increased due to some final touches all the way from 5 kcps to 8 kcps, mostly because of using phi2s instead of phi2 for sync. Surely there’s room for improvement – next I’ll probably try halting the CPU when updating the latch – but as the speed is already more than 30x compared to the cassette port, there shouldn’t be too much to complain about. Thanks to Tero for his help and comments, too!

edit: Fixed the pinout of the expansion port.
