A Look Back In Time

From 1500 Pounds To Fifteen Ounces

When you're out and about with your little camcorder these days, look back to 1957 and this first Ampex VR-1000 machine.

As a boy of 11 years old, I was lucky to be able to puppy dog around with a broadcast engineer at KGO-TV in San Francisco, when they got their first "video tape recorder". An early education into capstan and head servos, and tracking, and video bandwidth etc. One hour of recording on a roll of tape 2 inches wide, and spooled onto an aluminum reel 10-1/2 inches in diameter. It whizzed through the machine at 15 inches per second. One hour of Scotch recording tape for $300.

Power..like a four burner electric range, 220 volts 2 phase.

The shipping invoice probably read something like this:

1 each
Ampex VR-1000 Video Tape Recorder
$120,000 (1957 dollars)

We've come a long way.
