Now, Ruud's schematic he sent me differs from the one on the web site, as this one has a 62256 and a 6116. If we need those, That halves the board density, and we go to $8.00 a board. If I go SMT, I might be able to get back down to 12 boards per sheet, or 20 boards without the RAM, but SMT is harder to solder. Obviously, prices quoted are back of the envelope, and I could be off $1 or $2 per board. Prices quoted are for non silk-screened, non-soldermask boards. I use www.custompcb.com full panel service, if you want to check prices.
