RE: HHP-32k 41C ROM Emulator - Dip switches?
It looks like a second PCB was piggybacked onto the 16k version of the board to make the 32k version.
The top set of switches are still the configuration DIP switches. The middle set of switches would be the address switches for one of the EPROM's, probably the one with the socket labeled B1. The left set of switches would then be the address switches for the other EPROM, the one labeled B2. or One set of address switches is for the top half of B1 and B2 and the other for the bottom half. This looks more consistent with the 16k manual on TOS. Dave |
