8032-back.jpg 2009-08-18 51292
The C2N232 device between the rear cassette port of a CBM 8032-SK
and the RS-232 port of an IBM Thinkpad A20m.

The C2N232 device inserted between the side cassette port of a CBM
8032-SK and the RS-232 port of an IBM Thinkpad A20m
8032-side2.jpg 2009-08-18 35207
A CBM 8032-SK is loading a program from an IBM Thinkpad A20m that is
connected via the C2N232 device.

A family portrait of a CBM 8032-SK computer, a CBM 8250 dual disk
drive unit, a CBM 4022 tractor printer, and a C2N232 device
connecting the CBM 8032-SK rear cassette port to an IBM Thinkpad A20m.

A DB25-to-DB9 adapter case modified for the "smdcr" board. Something
is sawed off from both sides of the wider end.
case2.jpg 2009-08-18 14920
A DB25-to-DB9 adapter case modified for the "smdcr" board. The bottom
side of the cassette connector is glued to the case. The photos were
taken by Nicolas Welte, who made this modification.
smdcr-bottom.jpg 2009-08-18 267186
The bottom side of the first unit of the first production run of the C2N232.
The components were desoldered from a prototype board.
smdcr-top.jpg 2009-08-18 273556
The top side of the first unit of the first production run of the C2N232.
The device is powered from a Commodore cassette port (bottom). The
permanently installed jumper wire at the bottom right makes it possible to
update the AT90S2313 firmware when the jumper pad at bottom right is closed.
The DB9F connector provides an RS-232 interface for the host computer.
A three-wire interface (RxD+TxD+GND) suffices for normal operation; CTS/RTS
handshaking is needed for updating the firmware.

A Commodore VIC-20 equipped with a 32-kilobyte memory expansion,
connected to an IBM Thinkpad A20m via the C2N232 device for invoking
a game of Omega Race.
