I began computer life with a Radiator Shaft TRS-80 model one unit. It was notorious for crashing because of a dinky ribbon cable that connected the keyboard to the CPU unit. Also, the copper connectors on both the keyboard and CPU developed tarnish constantly, which required frequent cleaning.
This "computer" had an external cassette machine for transferring data to and from memory. Slow? Yes. Cumbersome? Yes. Reliable? No. I think that I had a grand total of sixteen kilobytes of RAM.
The monitor was black and white. Actually, it was more of a ghastly green and black.
From that dismal digital scene I advanced to a TRS-80 model three unit which was a slight improvement. The model three combined the keyboard and CPU in one enclosure which proved to be a bit awkward.
Despite these digital "dark ages", we still wrote "computer music" with this ancient equipment. I used a software/hardware combination known as Orchestra-80 in those long-ago days. We were limited to five simultaneous voices and each of them sounded pretty much like an organ, but it was a good learning process.
