TOPCON HA-3 with HP-71B
#1

I have one of these units and was wondering if there is a manual out there somewhere for this unit. Also, is it possible to upload and download files to a PC? This unit has an RS-232 port and cable to connect to the PC.
Any thoughts?
Thanks,
JeffD

I've never actually seen one of those, but I've gotten the idea from somewhere or other that the serial interface is compatible with the 82164A, so the usual methods should work. I think there have been postings in this forum about that.

I think you can upload a text file to the PC using something like:

COPY FOO TO :INTRFCE

For BASIC programs, you're best off using TRANSFORM to convert them to/from text. I'm not sure if you can do this directly to/from the serial interface, so you might have to do it in memory first.
