HP 97: Disable printer?

[[kby]]

Not that it would be a desirable solution for this case (unless the ICs were available and the boards already socketed, do you think swapping the (appropriate, probabltb#0) ROMsbetween a -97 and a -67 would work?-kby

I keep the calculator in MAN mode, but it would be nice to include PRX in programs for the long-pause effect from the 67, or actual printing later if I get the printer working.

The 67 and 97 share some code but not in this regard.

It might have been nice to have this functionality but there would need to be another ROM added to store the extra code and a method to activate it.
