Report on vintage "Programmer Electronnic Control" alias "RAF Tornado Computer"

Hi Lyle, thank you very much for your email. On Thu, 8 Mar 2007, Lyle Bickley wrote: Thanks, but puzzling around this unit is very exciting and thrilling. People who designed this where very clever and often one can wonder how tricky things are done. For example is the adder of the ALU used for address-generation as well to reduce number of chips required. Lot of open-collector logic to have the freedom to make wired ORs, i.e. doing logic without chips. Very clever at many places... Yes, this would be great, but my hope is very limited. I think all units have been scrapped long ago and the few which remained have been put apart for the core memory and the rest was trashed to... :-( But hope dies last... Best regards, Erik. P.S. > "Black holes are where God is dividing by zero" How do you explain the different sizes of black holes?
