Re: Latest Pendant design with wiring diagram W/Keyboard Emulator

I'm not authorized to see that url, but I had given terminal
emulators a thought since I saw someone marketing one for around
$250. All that was was an old desktop scientific calculator,
apparently gutted and replaced with standard keyboard keys. I
thought of gutting my old Teal SR85, but discovered that the
calculator museum wants it. So there I am a slave to my obsolete
surplus. Maybe an old gutted cell phone would work. I believe you
can't beat a standard $5 keyboard. If you want something special,
turn the keys 90 degrees and hold the keyboard sideways, or saw it
in two. Now that's progress. Charles Hixon
