OK, so it turns out Tandy were quite smart with the variant of Coco 1 that I have. The RAM upgrade just requires 4 jumpers to be changed, 8 RAM chips (416's basically the same as a 4116) to be swapped, and the removal of 8 capacitors (C70 to C77).

Yes, reports of cooking foil + foam mat stuck with Spraymount work fine. Best to use the original circle of plas...

It is but not a problem I've run into before, even post Brexit. It depends upon whether the customs has picked your shipment to look at or not. Some things from across the pond come unmolested but others (like my last Best Electronics shipment) get the duty and the processing charges added and VAT ...
