" If the motherboard SIMM or DIMM sockets have tin plated contacts, then you must use SIMMs or DIMMs with tin plated contacts. If you mix dissimilar metals (tin with gold), corrosion on the tin side is rapidly accelerated, and tiny electrical currents are generated." ...etc, etc. You get the idea.

Thank you for your work around.
I will get your 14Mb for sure unless I can't find a 14Mb expansion for my Falcon
Anyway, so great to have your solution on the way.

Its a tight fit, but I've had a similar one in my falcon for years. I just have some thick card on top to make sure the metal shielding doesn't touch the top of the board at any point.
Incidentally, I have got a new batch in production, Just waiting on the PCB's to arrive. I've got the simm sockets and other bits already.

I should think the PCB's will be here around the end of the month (china new year holiday holding things up currently) . Then its just a matter of time to assemble and test.
