I discovered several D116 paper tapes in my garage with original labels. I was wondering whether there was a way I could attemp to read them manually. The tape has 8 bit positions. Three hole positions, tractor drive perf line, and then 5 more hole positions. All the tapes I have appear to be Octal debug, extended debug, ALU exerciser, Mag Tape Diag. D116 Loader and DG Loader. Is DG format different than D116 Format? Most interesting handwritten label is something called "Twiddle" I think it is a sample program or a front panel light excerciser. Any Help with decoding Digital Computer Controls D116 Code on Paper Tape? I have a D116 and the Paper tape reader, but nothing on it's assembly code Or D116 programming. Asre there any D116 site out there??
