The observatory clock complete with 30 year old nixie tubes.
There was a UTC clock and a sidereal clock, both driven by quite accurate temperature controlled crystals.
The tubes disappeared in early 2009 when the interdata model 70 was decommissioned - the new computer doesn't know how to drive them, and we use a GPS clock now. I've taken the nixie tube javascript clock and hacked it up with photos of these (and the nimos we had in the observatory clock), and they are now on the controlroom mimic. (the javascript clock part of the mimick looks like this).
My home made Covox Speech Thing Digital-to-Analog LPT (parallel port) stereo sound card. Fairly easy to build. The sound is not perfect but it plays stereo, 44kHz!

1200/75 modem as supplied with the Open University Hektor III. No autodial here, you had to dial the number on a phone and flick the switch to 1200 or 75 when the machine at the other end answered.
We also used this with our BBC Micro until upgrading to a Watford Le Modem.
