On the subject of 1900's:

A long, long time ago (late 1975-early 1976), Computer Weekly1 ran a "Win-A-Computer" compebreastion for schools. My school (the then Keswick Grammar) entered a project analysing Cumbrian Stone Circles using a HP 9830A2. We came second. The first prize was a DEC Clbuttic minicomputer. The day of the prize-giving clashed with one of my "A"-level exams, so I missed out on getting my photo in print and meeting Patrick Moore.

Soon afterwards, a firm that was retiring its old 1900 donated it as a "second prize" to our school, just as I was leaving. My brother played with the bits and pieces (what on earth were a bunch of school children supposed to do with them?) and preserved some of them. A couple of weeks ago I helped him to clear out his loft, and rescued a box of manuals.

I note your posting here of 2005-02-263, so if you are interested in any of the below, let me know. I'll look after them, and make sure they aren't lost to posterity.
