Well, I've finally got the right-sized piccies for the different DeclROMs in question:

Duo MiniDock: socketed 32 pin PLCC DeclROM





DuoDock: SMT 32 pin _________ DeclRom



DuoDock II: ZIF Socketed 32 pin _________ DeclRom:

w/retaining frame in place:



w/o retaining frame in place showing Pads & Legs of 32 Pin _____________ DeclROM:



32 Pin PLCC Prototyping Socket:



It's just a matter of designing a circuit board, or even a wiring harness, that'll connect to either the DuoDock on one side or the DuoDock II on another. It will need a switching setup to control the Chip Select lines of whichever DeclROMs are being tested, which is a far more elegant approach than the PowerPinJumperHack seen in the DuoDock DeclROM piccie.

32 Pins in each case pretty much translates into each of the 3 ROM ICs having the same storage capacity, despite the disparate IC Packages & mounting technologies.

I'm tired! Time to log out for now!
