"Your Guwange PCB should have one 42pin 27C040 Eproms on a socket."
But my board (and, from what I can tell, the one in the picture under the hardware section on the same site) appears to have 2 32pin eproms.
Just want to double check that I'm not missing something before i order 2x 32pin 27C040 . . . .
