These photos were salvaged by Peter Wooster when Reuters Canada shut down its operations in the Exchange Tower in Toronto. There are four groups of photos:
A] Mainframe hardware at E.T.((two images)
B] 3705 and Alpha hardware at E.T. (two images)
C] CAI LSI-2 boards owned by Peter Wooster which he has photographed. (two images)
D] English (London and Oxford) Alpha installations of various sizes
E] Continental Alpha installations of various sizes

I have created five different index pages for the benefit of those with limited bandwidth connections. I have provided hasty incomplete captions for the Toronto pictures. Any help in identifying mystery component would be appreciated.

Synchronous Modem Controller (SMC) was a CAI device to attach a single Bisync line to an Alpha. The large white chip is labelled: top row COM2501 bottom row SMC 7/11. The black chips for 74xx or 74xxx types. The silver vertical lines between the chip rows are metal rails. These rails provided stiffening and distributed +5V and ground to the chips. The upper edge connector served two purposes: jumpers provided device and interrupt addresses; an RS-232 cable connected here.


Core Storage. This board provided 16,384 16-words (32K bytes) of storage with a 1200 nanosecond cycle time. It was possible to install two boards to double the memory size but this was not normally done in IPSANET nodes.
