Tektronix 4054A with Option 30+31 Color Dynamic Vector Graphics Demo

Tektronix introduced the 4054 Desktop Vector Graphics Computer with 19 inch direct view storage tube in 1979 and also introduced the Option 30 Dynamic Graphics card at the same time. This video shows the Dynamic Graphics coprocessor drawing refresh vector graphics at over 1000 vectors per second on my 4054A computer which also has the Option 31 Color Dynamic Graphics CRT which was introduced in 1982. The Color Dynamic Graphics CRT contains both green and red phospors and the red phospor has very short persistence while the green phospor can be written at higher energy and persist on the CRT. At lower beam energy for refresh vectors - both green and red phospor glow with a combined color of orange. I recovered all of the Option 30 demo programs from a tape from the estate of Jack Everson, a Tektronix sales engineer. In this demo - all the programs have been saved to my GPIB Flash Drive - which completely replaces the need for a working DC300 tape - and supports saving and loading 100's of tapes in separate directories on a microSD flash card! This video will demonstrate all the programs on the Option 30 Demo Tape in COLOR on my 4054A with Option 31 Color Enhanced Dynamic Graphics CRT!
