TechRepublic's Mark Kaelin runs Lotus 1-2-3 on an IBM PC from the 1980s, and revisits the quirks that meant the machine was doomed
Lotus 1-2-3 allowed for the limited use of colour. This is one advantage the PCjr had over its corporate cousins — many of them were still working in monochrome.
As IBM clone machines became more prevalent, the PCjr was quickly doomed by its quirks — such as the lack of standard connections and upgrade ability.

I remember this piece of shi... err underperforming bag of nonsense.
All that non-standard connection periphery was a precursor to the "new standard" - PS/2, that similarly fell on its err.. bottom.
IBM continued to try and con the public and exploit its dominant position, The PC Junior was just one example of this attempted manipulation, and was the first of many bloody noses, dealt by the market to the smug face of IBM.
IBM tried to force its dealers (I was one of them) to take pallets of these at risk of losing their dealerships. We lost ours, and made a mint selling Compaqs.
