EPROM BOARD SCHEMATIC
This isn't a "real" printed board; I've used wire; if you want to make a "real" printed board simply connect all the similar pin of the eprom together (for example pin A0 of socket 1 with pin A0 of socket 2 and 3 and 4 etc.).
NOTE: in eprom where OE (G) and VPP have the same eprom pin (example: 27C32, 27C512), simply connect it to VPP and ignore OE (G).
