old terminals...

Old terminals In the UK in the early 1970's I worked for a (then small) UK company called Newbury Labs. We made VDU's or video terminals. The early types used eight bit parallel shift registers as screen memory. The model number was 2480 i.e. 24 Rows of 80 Characters. They came in steel enclosures (painted blue!!) The screen was a 12" tube as used in mono portable TV's. We used to spend half an hour on each one fixing up the screen geometry with small magnets. The newer ones used a crude stored program system made out of TTL ie no Microprocessors.
