The Sharp PC-1500 is a small computer from the early 1980s that can run programs primarily written in BASIC. Programs can be saved to and loaded back from cassette tape but to do this requires it to be connected to the CE-150, a cassette interface that also includes a four-colour plotter. It’s the plotter that really attracted me to the computer in the first place, but being able to load programs from cassette rather than having to type them in by hand is definitely a very handy feature.

Ben Ryves restores a PC-1500 but has problems loading in programs downloaded from the internet – the beginning of the “tape” file doesn’t have the sounds needed for the computer to recognize the recording as a valid program.

When looking to see what other people had managed to achieve with the computer I found the Sharp PC-1500 (TRS-80 PC-2) resource page which hosts several games and applications which can be downloaded in WAV format. I downloaded a few, but when playing them back on my PC the PC-1500 would refuse to load them. It could load from my own recordings, why not these?
