I love how he talks about knowing thermal characteristics, etc. and then cites the TI-99/4A as an example of something designed by people who Really Knew What They Were Doing. The TI-99/4A was notorious for being prone to overheat due to its power supply. Munch Man and Parsec were complete non-starters for me when it got hot in July. This was even mentioned, specifically, in Halt and Catch Fire. The early microcomputer engineers were spitballing. You want to talk about the number of bodge wires that were in every TRS-80? Or the Apple III having no thermal vents per order of Steve Jobs, and the "you're holding it wrong" of the 80s being "drop it on your desk to fix it"? We know how to build better, more reliable computers for cheaper today than we ever did in the 80s. Then we fuck them up with things like Windows, but still.
