| Jan 5, 2017 at 22:09 | comment | added | supercat | Any idea what other sizes of delay shift register were available, either static or dynamic? I would think it would be possible to double the speed of the machine if the program counter were stored in a 128-bit shift register, and bytes were stored in interleaved fashion. If the the longer shifter held address 000[octal], 010, 020, to 170, then 001, 011, 021, up to 171, etc. then instead of each instruction fetch requiring a full lap through the long shift register, eight fetches could be handled on each lap. | |
| Jan 5, 2017 at 7:01 | comment | added | PkP | That's absolutely brilliant! I didn't realize so large delay line shift registers were available so early. That's a real computer, made from TTL chips. The complete schematics is in the Theory of Operation document from your link. kenbak-1.net/index_files/Theory%20of%20K-1.pdf . What a treat. Must investigate further. +1 from me. Cheers! | |
