Notes from the Museum

Cliff Horrocks 1921-2012

Cliff Horrocks is already greatly missed at TNMOC. Below is Cliff's obituary from his family.

A Dragon Breathes Fire Again

Dave is a fellow volunteer at TNMOC with a bit of a passion for the 6800 processor and he has recently been working on a US computer known as the SWTPC 6800.

The Elliott 903 takes a step closer to restoration

It is rarely quiet at TNMOC, certainly not when we have volunteers and visitors around. But from time to time you hear a special kind of sound, one that is perhaps filled with a little excitement and expectation.

Wilkes on ENIAC, a personal view – 1947

A paper written by Maurice Wilkes in 1949 discussed issues about ‘programming’. Brian, our volunteer archivist, showed me a 1947 magazine in which Wilkes wrote about the ENIAC.

Programming for a high speed automatic calculating machine. (M.V. Wilkes).

A volunteer at TNMOC doesn’t spend all of the time with hardware and software, or even our visitors. This week I found myself sorting through some old documents, which I confess I find fascinating and came across a draft of a paper by the then Maurice Wilkes, later to be Sir Maurice of course.

Plastic flip flops from the 1970s

We get donations of all types of calculator at TNMOC, but rarely something like the BOBCAT. The Ball Operated Binary Calculator and Tutor (BOBCAT) was once used as part of an Open University Course.

QWERTY - something consistent across the years

TNMOC contains many computers from across the decades. But there is something you will see over and over again: the keyboard used to communicate with many of our computers.

One analogue of a desktop, the TR-48 ticks away

One of the Museum’s galleries is dedicated to the less well-known, analogue computers and includes an exhibit of a working TR-48 desk top analogue computer (c1961) available for our visitors to see.

Ele leads the code stitchers at TNMOC last weekend

Something different was happening at the Museum last Saturday. Between the clicking of Colossus, the whirr of the Elliott and the beeps of the Beebs, our meeting room was a buzz of activity - stitching the code.

Out with the new and in with the old

Last year the Museum acquired an authentic Calcomp 565 drum plotter that had once been part of an Elliott 503 system. The hope was to connect the plotter to our working Elliott 803 computer, and so the work began.
