Earlier this year, I bumped into [Wayback/Archive] The Trash Computer That Became Your Phone – YouTube which discusses the Tandy TRS-80 Pocket Computer PC-1, . The video includes a lot of history about Tandy Corporation, Charles Tandy and Radio Shack including quite a few bits I didn’t know yet.
It was part of the Tandy Pocket Computer, and succeeded by the Z80 powered TRS-80 Pocket Computer PC-2 (which was actually a rebadged Sharp PC-1500).
The TRS-80 Pocket Computer PC-1 itself was also a rebadged Pocket Computer, this time a Sharp PC-1211 powered by a duo of 4-bit CPUs so totally incompatible with the PC-2. Actually none of the Tandy Pocket Computer line were compatible with each other (nor with the desktop TRS-80 which itself was incompatible TRS-80 Color Computer). With the PC-4 and on Tandy even switched to Casio as manufacturer, then back to Sharp for the final PC-8.
Anyway: this video was a trip down memory lane and reliving my 2012 blog post The calculators that got me into programming (via: calculators : Algorithms for the masses – julian m bucknall), and I was glad that by now there are more videos covering the calculator I started with, for instance via [Wayback/Archive] sharp pc-1211 – YouTube:
