Presently in order from fastest to slowest.
I'd like to get a list of speeds for a much simpler program, that ONLY goes after one thing: a loop of additions.
where the stack contains 0 1 1 1 on 4 level machines. In other words, start with 0 and do repeated additions of 1 for 60 seconds. What is the result? I know Xerxes' test checks many other things, but how do they stack up with this?
Please post:
The machine used
Your count after 60 seconds
Your program code.

03 "SeeRemark" !!! Synthetic string 9 long Decimal 249 96 7 117 131 131 131 64 178 176
this places 96 7 in N to be transferred in reg b, resulting in program counter in reg M, byte 6
In reg M synthetic code results in:
RDN ENTER ENTER ENTER + GTO 01
The GTO 01 is a COMPILED GTO jumping to the + before it!
You can SST this code but the GTO 01 takes a long time to reposition!
Yes, this can be optimized still a bit, but the loop is using 3 bytes!

INSTRUCTION: READ THIS

wait until beep, 000000,06 is displayed
press [R/S] to start counting
press [R/S] after 60 seconds, write down the count
perform a GTO .. !!! because the program pointer is in reg M, switching to program mode and TOUCHING A KEY results in MEMORY LOST!
