E: Shift Registers as Delay Lines (was Delay lines in TV

[Steve Thatcher]

actually Texas Instruments had a quad 80 bit MOS shift register package available in the early to mid seventies. I had used two of them for a frame buffer on a CRT controller design I did. The part number was TMS3409 I believe and it was something I got from the surplus market.
