I've been gathering parts for my Zeta build, and I discovered, from a dead motherboard, a winbond w25x80 flash bios chip. It's an 8 pin, 8mbit part, and looking at the relative pinouts, it's almost the same, but expressed in different language. Datasheet here: http://www.winbond.com.tw/NR/rdonlyres/E1EAF68E-115A-4533-9384-FA31B9126F6B/0/W25X10_W25X20_W25X40_W25X80.pdf
Has anyone tried one of these things in place of the 24LC512 on the parportprop? It looks as though it should, at least, not go up in smoke - power and ground are in the same place.
Also, how critical are the 130 ohm resistors on the parportprop? (r18-20) I've inadvertently soldered 120s instead of 130s. They're within 10%. Do I need better than that?
