||HP's last Woodstock model. A very cute little unit! Like all
very small and handy. Compared to the HP-25C it is much more powerful
overcomes all of the former's programming limitations: Twice as much
memory, subroutine calls, numeric labels, instruction insertion and
and more. Most importantly it fixes the HP-25C's number termination bug
or was that a feature?
The only thing that didn't change compared to the HP-25C is execution
When compared with Classic models it falls in the category of the HP-67
lacks the card reader. Compared to Voyager models it's feature
set comes close to the HP-11C.
Feature wise the unit is identical to the HP-19C.
