I sumbled over this wonderfull items of my roots in computing. With the C64 I learned coding (I had no medium to save anything, so every time I started it, I had to built something myself first)
And the Cray was a dream back then. Cray not only made the supercomputers of that time, they made them stylish too. There was one with a watercooled system. They made a well out of it!
NT666003, LR80.
HISTORY
Pillar completed 23rd March 1954 costing £48.2s.0d. Computed as tertiary triangulation station NT72/T100 within the Jedburgh secondary block during 1957, and levelled to second class precision in 1958. This pillar station was last maintained by the Ordnance Survey in October 1986.
SITE VISIT
Approached from the northeast. Parked on the farm track adjacent to a barn, with the kind permission of the farmer at Chattlehope, NT738028. The endurance testing three trig circuit included White Crags, The Grun and Ellis Crag. Deep heather, plenty of bogs, no paths, long peat troughs etc. A flat topped bleak heather clad moor. The pillar is in good condition. The spider retains its original OS centre cap with deep indented lettering. The flush bracket faces south, compass measurement 191°. Vented through the front (south) and right (east) sight holes. The panoramic outlook includes Deadwater Fell.
Photographed: 17th May 2008, GRP.
