Quote from: Bryce on 14:56, 11 December 10The resistors are pull-up resistors for A17 and A18.
Quote from: Bryce on 16:53, 12 December 10A17 and A18 coming from the CPC aren't connected to the EPROMs A17 and A18, so the CPC thinks there's a 128K EPROM attached (A16 to A0), the DIP switches / resistors allow you to set A17/18 on the EPROM/Flash to 00, 01, 10 or 11 to select the region of the EPROM which is addressed and what the CPC gets to see.
