I've tried Mark's circuit and it works just fine. If, however, you have one of Phill's (Prime) MRBs then you can have up to 8 different languages installed and just select the one you'd like with switches. It just involves reprogramming the MRB ROM - no other changes to the Electron!
If anyone wants to add a 2nd, 3rd etc. language - program as follows:
2 languages = 39SF010A (I ship MRBs with this part) - 4 languages = 39SF020A - 8 languages = 39SF040A
RA18 RA17 RA16
0 0 0 ROM set #1
0 0 1 ROM set #2
0 1 0 ROM set #3
0=link closed.
Etc. - You get the idea!
