Are you sure it wasn't the massive over-funding by government that
killed it?

Judging by the year, it was probably a teletext
terminal. There were
various field trials of such systems around that era.? We had one in
Toronto's Eaton Centre - it was based on NAPLPS, and used a PDP11/23.
There was a lot of Canadian Government money put into research to
promote he Canadian vector-based protocol, claimed to be more
efficient than the European alpha-mosaic ones.? Ours ran at
1200/150(?) baud.
Research was done at a Bell Canada site on Carlingview Avenue in
Ottawa under some sort of sub-contract.?? They used Able DMAXes on an
11/70 which had a pot to adjust the 150 baud clock.? They actually
flew me up from Toronto, with a scope, to adjust that pot, since
everybody there was hands-off this external stuff.
It may have had a future if HTTP and the internet were not just
around the corner:-)
Well I think Hook up up to your TV and slower than? hell cheap decoders
killed the NAPLPS rather than the internet is comming.
