There was an improved circuit board for a C2N232I that features a serial bus connector and in-circuit programming via the RS-232 interface. I never got around to completing the protocol translator for the serial bus. And nowadays there is sd2iec, so there is little motivation to continue. If I remember correctly, the ATtiny2313 is a drop-in replacement of the AT90S2313 when it comes to this circuit. There is a separate firmware that was adjusted for the software-side differences between the ATtiny2313 and AT90S2313. >Sorry but the documentation about C2N232 could be a bit better maybe :) It is not a commercial product. :) I have been thinking of putting all my old C= stuff on GitHub so that it can be forked easily and pull requests be submitted. Some day I should really do that. Marko Message was sent through the cbm-hackers mailing listReceived on 2017-02-06 18:01:41
