Volker-Craig Ltd. was a Canadian manufacturer of video terminals, founded in 1973 by two University of Waterloo graduates, Michael C. Volker and Ronald G. Craig. They were early arrivals among dedicated makers of terminals. TeleVideo wasn’t founded until 1975, and Wyse Technology didn’t appear until 1981. Volker-Craig’s early designs, like the VC303 and VC404, were TTL-based. The first microprocessor had gone into production in 1971, but most terminals didn’t have (or need) microprocessors until the late 1970s.
The TTL models were later replaced with microprocessor designs that offered emulations of other manufacturer’s terminals in addition to VC’s own command set. The VC4404 “Chat” contained a 6502 and could emulate the Lear Siegler ADM-3A. However, the VC4404 had a feature that some people saw as a bug; the character cell containing the cursor alternated between showing the character and the cursor, which was especially annoying if the cursor was an underline.
Another Waterloo company, Keynote, made a graphics board for the VC4404 that added Tektronix graphics1 capability. This board, at $600, was half the cost of the terminal it supplemented, which made a cheap graphics terminal.
As far as I can tell, Volker-Craig subcontracted production of the terminals out to local firms. Mott Manufacturing Ltd., now a laboratory furniture maker, made the terminals and Qupro Data Systems Ltd. (defunct) wrote the control firmware for the microprocessor-based terminals.
In 1981, Volker-Craig was sold for around $7 million to NABU Manufacturing Corporation, based in Ottawa. John B. Kelly's NABU (Natural Access to Bidirectional Utilities) offered a primitive Internet-like service that distributed content and applications via cable in the early 1980s. Consumers bought a $1000 S-100 PC that booted a CP/M-compatible operating system over the cable. One of the board’s designers, Mike Slinn, still has some NABU games board development photos2 online!
In 1984 NABU Manufacturing Corp. became NABU Network Corp. and the Volker-Craig name returned as Volker-Craig Technologies Ltd. I don't know the circumstances of this separation or who was involved.
Volker-Craig Technologies then made some terminals that were compatible with DEC products. The VC-2100 emulated a VT102 and the VC-5220 was VT220-compatible. This latter model was certainly still available in 1986, costing $1198.
I don’t know when Volker-Craig finally closed.
The University of Waterloo in Ontario has a rich history of innovation in computing and technology spin-offs, of which Volker-Craig was one of the first. The University remembered its alumni by buying lots of VC terminals! Today the area of Waterloo, Cambridge and Kitchener is known as Canada’s Technology Triangle.
How well did VC terminals sell in other countries? How many staff were there? When did they finally close? Photos of terminals? If you have anything to add, please email me.
