-
- I think the main problem that you perceive here is the response time of the
- serial mouse.
-
- First, lets define the mouse! A normal "pc" mouse only works at an output
- baud rate of 1200 baud!
-
- While there is hardware in the pc to handle that, and all the pc has to do
- is update the pointer position at the end of the string of bytes from the
- mouse, 3 to 4 usually, the amiga serial mice conversions I've seen would
- appear to be stuck in a busy loop polling the port with a software uart for
- the entire duration of that 1200 baud data transfer!
-
- That translates into a pointer update rate of far less than once per field,
- more like 1/3 second per move assuming the amiga can move it instantly once
- it has the data. To me, that would seem indicate a need for a new
- definition for the word "jerky", the present one isn't at all adequate!
-
- BTW, go look at how a pc mouse pointer moves in fact. Then you'll truely
- understand that we Amigan's are indeed spoiled! Fat cable, doofy
- construction vis-a-vis the switches, optical wheels are the damndest lint
- grabbers, the balls can't tolerate pizza grease on the pad at all, but when
- it works, its sweet!
