Class: computer
Machine: Titan
Condition: good
Notes:
DW: These are printed circuit boards from the Titan which in fact were identical to those used in Atlas. Life hasn't proceeded very far these days. There are individual transistors, individual resistors, diodes. They plugged into a back plane through gold plated contacts and there's a slight curvature here to allow for easy insertion. A box held 50 of these circuits and a rack held about 10 boxes and in Titan for example there were about 3 racks, in Atlas perhaps 10 or 15 racks. So this is an example and here is another example of this type of board. There were altogether probably about 20- 50 different types of board for various purposes and they were numbered by a colour code, unfortunately this board seems to have lost most of its colour code and I'm not quite sure what it was. A typical board would perhaps have 4 2-input NANDs on it or integration - something like that. This is another board used for Titan but this was used for controlling peripherals. The construction is exactly the same except that there are far fewer components needed and this I suppose has 2,4,6 transistors and they were a little later version than the earlier transistor on this board.
Q: Who made these cards?
DW: These cards were made by Ferranti, who made them for the Atlases and the Titan. These components were the same for both machines. It has a number on - 10411474, whatever that might mean. There is another number here - 883. Later versions of printed circuits boards usually went to the trouble of putting a printed notation of what the boards were.
