Ben.
Me and my buddy are building an Apple I replica,
for now successfully.
Recently we have tested the video signal :) However, we are having big
problems (as you can imagine) with finding Signetics 2519 chips. I know
many ordered them in bulk, so I would be thankful for any help (we have US
address) or information.
If more than one 2519B pop up for less than the crazy eBay prices, I'm
interested. I have a Willegal Apple 1 board that I am still sourcing
parts for (esp 2519B and 2504/1404)
I am not worried about date codes or exact package styles or markings
(N vs P etc.) I just want it to work. In the short term, I'm
definitely willing to consider a board with 6x4557 programmable chip
registers, but that still leaves the 8-pin shift registers.
