[comp.sys.handhelds] HP42 AND IRED LINK

ralph.hempel@canremote.uucp (RALPH HEMPEL) (11/15/90)

I have been watching the net for some weeks now and have not seen a
message regarding the HP42S. Is the machine scorned or what? Two quck
questions which may be FAQ by now:

1. Is there some machine lang. capability for the 42. I have found a
memory looker-atter in the self-test sequence and can jump around and
look at memory. Can I change it too?

2. I have decoded the IRED stream based on the Journal Article and am
willing to share my circuit and software. It was done on a MC68HC11
microcontroller and I find it useful to use my 42 as a remote keyboard.
