Transfer files between HP-71b/PC and then to HP-75c

Richard,

Welcome to the small but still very active world of '71B users (and even smaller and somewhat less active world of 75C users). Indeed using the original hardware is both fun and challenging, but as you've concluded, the PIL-Box is the way to go. Without a PIL-Box, getting stuff in and out of the machine is the challenge, but with it, it becomes quick and easy to explore all the other possible challenges.

You're about to find out something which is probably a little unexpected: the 71B and 75C use very different dialects of BASIC, and there are lots of differences in many areas.

Coming from a 75, the 71 seems a bit smaller and similar to use, though more flexible and easier to program; the 75 is much faster for math, but slower for I/O.

Coming from a 71, the 75 seems a lot larger, a lot less flexible, requires tedious syntax for files and I/O, and is just more 'crude' lacking system features such as subprograms, an assembler, etc.

But both are still great machines and still fun to explore. Please join in and share your explorations, questions and discoveries.
