Boundless made CRT kits for decades
They are also on HP 16500 logic analyzers
I had a prototype IR touchscreen monitor for the Alto, but stupidly didn't hang
onto it.

My HP150 will have to disagree with you there.

And what sort of technology was that screen using? I expected to see
the grid array of outer infrared LEDs and detectors that I vaguely remember
from that era, but I don't see that here. Someone was making a tube
that was coarsely touch-sensitive?

You are absolutely right about the economics! The only one I ever saw in
operation was in the Eaton Centre in Toronto, just around the corner
from the Bell Simcoe office where I worked on the server!

You are probably right about the 6809, the stuff I worked on was all in
the development stages for the project, and at the server end. I did
field engineering for Transduction, and we supplied equipment to Norpak,
although I can't for the life of me remember what! I remember going to

More widely known as Telidon despite it being called NAPLPS.
It was called teletext despite the implications, at least here in
Canada. People just couldn't get their tongue around NAPLPS!
It looks just like the teletext systems I worked on, maybe ours was
better than yours?

It's not Teletext, unless that word means something different on the other side
of the Pond. Teletext was basically a text system (the hint's in the name)
Are you sure it wasn't the massive over-funding by government that

Hi!
I saw this crop up on twitter and now I’m curious. Anyone familiar with
