Bernhard;
You may well be correct. If so that's good news, with a clear explanation.
However; I've read the opposite here for probably 15 years from other knowledgeable people. So until I'm sure, I'll err on the safe side and urge "new" members with that question to err on the conservative side too. IF there is any greater chance of frying the ACT in powering it that way; I'd rather avoid the penance of buying another of your chips, the couple of hours changing it out, and the peeling and re-sticking of the backplate. I always hate that part.
I admit that charging the battery outside is an extra step. Probably everyone, except one of us, who has a working 67 also has a classic charging cradle or a relatively cheap 35, 45, or 80 though. So the hardware part of this is already taken care of. Even another classic with keyboard, display or other problems should work.
