I went to Bletchley for the first time on Wednesday. Tony Sale was there
and he let us into the machine room. It was fascinating to be stood
right next to Colossus's "bedstead" as the tape whirred around at 30
miles per hour, and to see the blinkenlights and valves.

I bought my cheap return ticket, so I'll make the next trip on a
Saturday to see the Retrobeep collection. (Sorry, I've been repeating
that name to myself in an effort to get used to it, and it _still_ sucks!)
