We hate 2020!

Just when we thought 2020 couldn't get any worse! We were about to re-open after many months of being closed but then disaster struck when a mains water pipe burst and flooded much of the ground floor of the museum.
Sadly re-opening has now been postponed. Read More >>>

VC4404 Terminal

Mike Volker and Ronald Craig were the founders of this company, they were the alumni of Waterloo Engineering, they were to produce some of the earliest video terminals. One of their customers was Samsung, who would later partner with the company.

This Canadian terminal contained a 6502 chip and could emulate the Lear Siegler ADM-3A.

As well as the ADM-3A emulation, it has it's own "404" mode.

One annoying feature of this terminal is that it does not have a hardware cursor - it displays the cursor by alternating a "cursor character" (either block or underline) with the character in the cursor position - this causes the character to flash when an underline cursor is used, which is why VC4404s are almost always configured to a block cursor.

Oddly there is no hardware cursor, it changes between a block character with the character in a cursor position, this causes the character to flash.

Manufacturer: Vokker Craig
Date: March 1982
