Hi all
I've just bought a Yamaha CX5MII and I got a few carts with it including a UPA-01 for reading the Playcards and a few cards with it. However I don't have the CR-01 card reader unfortunately. I've also suddenly got interested in the whole Playcard system and i've bought a keyboard of the same era (a PC-1000) which also uses Playcards.
So my question is - does anyone know how the CR-01 playcard reader interfaces with the UPA-01? It uses a simple 3.5mm mono jack plug, and I'm guessing that it is based on a fairly simple tape head based reader. There are plenty of USB magnetic card readers around so I was thinking about maybe trying to hack one of those to just get the audio out. However obviously don't want to fry the cartridge either!
Does anyone have any info on how the card reader worked and I might be able to replicate it?
Grateful for any thoughts
James
