EDSAC on your desk.

Well, sorta.. I have found a wonderful EDSAC simulator that runs on Windows or Mac. It presents you with the 'front panel' of the machine.. a CRT that 'looks' at the various memory delay tanks, other register displays, and some control buttons. One 'punches' programs into files, which are then presented to the sim and away it goes. Even (corny) sound effects. It emulates the machine as it existed in the 1949 - 50 time range. It is a 1.873 Mb file that explodes into the program and demo files, as well as two .pdf docs explaining everything. It can be had at: www.ocs.warwick.ac.uk/~edsac I have been playing with it on and off all day today. Sam: Possibly a neat item at VCF II would be to have a box running this simulator... it certainly gives instant awareness of what it was like back in the Old Days. Certainly on topic, I guess... ;} Cheers John
