That's unfortunate, because then he would be free to add new features
instead of worry about when to yield time to his pulse generator.

I'm very serious about this part; it would be a very simple matter indeed
and inexpensive to create an external device using a Parallax Javelin stamp
to read RS-232 or USB commands that would issue the pulses for him and thus
reliving him of that task.

Perhaps a new version of Mach is needed.

The problem is that Mach(x) was written from the ground up as a software
step generating program. Art sent me the source code of his "driver"
section,
and I immediately saw that it would be a HUGE effort to convert it to the
servo model of operation. About every 5 lines of code, it would check to
see if it was time to issue a step pulse! Also, the driver mechanism he
selected does not allow you to use floating point arithmetic, which is a bit
of a limitation.
Anyway, I think it would be impossible for someone to do this without
extensive help from Art, and I don't think he is interested.
