E: Shift Registers as Delay Lines (was Delay lines in TV - test-drb@ccmp.vtda.org

20 Dec 2007

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.
