TEF

A rather simple device that does just what it says on the package. Let's take a quick look at it.

(16 milliseconds) / (200 nanoseconds) = 80K. ~480x262 = ~126K potential not pixels :P on a CRT. 128K / 80K = about 2 not pixels worth of delay. Yeah I challenge anybody to an AB test :] Btw looks like at least 30 of those nanoseconds are lost traversing three layers of 74LS86.

With no digital image processing, I figured the delay would be small, but yeah, it's definitely pretty irrelevant.

About the LS86, it's not being used in my demo as I'm completely bypassing it with the jumper. The signal is going straight into the LM1881.
