Cassette interface for Sharp PC-1245 pocket computer. Also Sanyo MX-315L boombox.

A Sharp PC-1245 pocket computer from 1983, required an expensive add-on to be able to store programs.
But back in the day, I had built an interface to allow for saving data to my Sanyo MX-315L boombox.

The CE125 interface would have recorded to microcassette and included a printer, but was too expensive.
All that was required was a switch, two 0.1uF DC blocking capacitors, and suitable connectors and cable.

A pair of audio cassettes were supplied with the PC1245, they can be downloaded here:
