Re: Digitizing arms??

As the third-party designer of the first serial interface (as well as
mini-computer parallel interfaces) for Summagraphics equipment
decades ago, I can assure you that Harvey is correct in his caution!

It all depends on HOW OLD a unit you are getting. The first
Summagraphics digitizers had a 50-pin PARALLEL (no, not printer)
output. I conceived of and did the design of the first "converter
box" that translated this into serial RS232 output. They soon after
designed their own such unit and then incorporated serial output into
later digitizers.

But the caution is quite correct with digitizers of all makes: check
the drivers and interfaces carefully before picking one up, or you
may have more work in store than you intended.
