Hi, did a quick Google and found this link on a German Forum regarding the CX-032B chip.

Luckily I can read German and donor machines could also be a Sony TC 440 and Sony TC 580 which have the same chip.

I got some of my Dutch R2R friends to have a look at it as well and with a bit of luck they can design a circuit with disrete components.+ ?% C% x) K! [- F
