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. -ethan
