Hello,
does anybody know if I can swap a spectrum 48K (rubber keys) motherboard by a spectrum plus one ? Their motherboards are tbe same size with connectors at the same place, but I was wondering if I would have keyboard problems (arrow keys for exemple).
Thanks !

Re: Spectrum motherboard swap with plus
A motherboard from a plus case can certainly be swapped into a rubber key case.
A motherboard from a rubber key case can be used in a plus case, but Sinclair did recommend some alterations. Details in the documentation (see here).
The other difference is that the motherboard in the Plus case has a reset switch directly wired to the board. The rubber key does not have a reset switch.
