- The PDP-10 could fall into this classification without too much arguing.
- It had its set of 16 general purpose registers defined simply as the
- first 16 locations in memory. Naturally, they implemented the the
- "registers" as logic (register files) rather than core (in the first
- ones). The secret way to get your program to run really fast in
- a tight loop was to load it into the registers (up to 16 instructions)
- and then jump to one of the registers......
-
- Ok, so its not so fast nowadays.... .....but still kinda neat
