HP-67 DSP vs FIX

[Matt Agajanian]

Hi.

I’m thinking it was a possibility since Woodstock had 30 keys with f & g prefix operations, that made for less keycodes as compared to 35 keys with f, g, AND h prefixed operations.

Since the 67 was built on Woodstock technology, that would mean that if a 25/25C had FIX n already, why would the 67 need the two-step FIX DSP n?

Lack of enough free keycodes. FIX 0-9, SCI 0-9 and ENG 0-9 require 30 keycodes in all, not that many were available.
