Only for info :-)

The simulator is slowed down to an average of instruction times.

The plot took 184 iterations to complete, with one SIN(x) per loop, so the simulator is running a little bit fast.

A lot of instruction execution times for the HP-9100 are in the 45 - 350uS range and complex math (SIN, hyper arc TAN etc) in the 100's of mS range.

Depending on (x)
the HP-9100 SIN(x) max processing time is 350mS
the HP-45 SIN(x) takes about 2200 instructions which is around 600mS.

For its day, the 9100 wasn't all that bad at its processing :-)

cheers
