C2N232 is a Commodore C2N cassette drive (datassette) emulator with an RS-232 interface. It was designed by Marko Mäkelä (http://www.funet.fi/~msmakela/).
The hardware design (made with the Eagle layout editor by CadSoft) is based on two integrated circuits: an Atmel AT90S2313 microcontroller and a Maxim MAX232 line driver.

Cost reduced surface mounted design of the board. There are no resistors, and only one type of capacitors are used. The originally planned 470 nF capacitors have been replaced with 100 nF. The microcontroller is programmed via the RS-232 interface. The files are in CadSoft Eagle and PNG formats.
