When the ZX81 came out I spent all my pocket money savings on it. First on the thing itself, later I would shell out for its 16K RAM extension.
Restoring software on the ZX81 using cassette tapes was so slow and cumbersome that it was quicker to restore it from my own memory. I had a little scrolling evasion game that I knew by heart, and I would type it in if I felt the need to play. Changing little aspects of that game (first different characters for the obstructions, then game mechanics) was what set me on the path of programming.
My brother somehow salvaged that first ZX81 from our parents' estate and it is now hanging framed on the wall next to me as I type this.
I am solidly in the first category. I throw dinner parties, birthday parties, drinking parties, dance parties, midsummer parties, midwinter parties, game parties, etc. Yes, it costs time and money and is a lot of work. But what people (probably the ones that never bother) tend to forget is how unbelievably gratifying it is to get a bunch of people together, to feed them and to make them talk, laugh, dance, etc. Afterwards you are tired but also grateful and socially energized in a way that feels fundamental to my existence.
He claimed that in the early days there was a lecturer or professor there that, at least in Eindhoven, was very important to his field of expertise. If I understood him correctly, this prof's ideas about engineering mechanical systems revolved around restricting the degrees of freedom as much as possible. A three legged table cannot wobble, but a four legged table can and usually does because it is overdetermined. In mechanical systems (for instance sensitive optical mechanics) reducing "wobble" is key. And the best way to reduce wobble is to make sure it cannot occur.
Here it gets interesting. My source claimed that this professor had laid down his ideas in a standard work in Dutch, which was never translated in another language, restricting its influence to Dutch mechanical engineers. He also claimed it is not a coincidence that Philips and later ASML took an early lead in designing optical systems.
Not sure if it is true, but an interesting story nonetheless.
