 |  Re: Possible 8501 replacement kit?
As I see the biggest problem: there is not enough free space available within the Plus/4 to close the keyboard if you do not use the original IC.
So even with working converter board, it will be hard to used.
But from the original 8501R1 still some thousand pieces are available, though they are really not cheap.

You should search for 8501R1
Maybe we should add it to the non-existing "important shop" list. ;-D
Still >9900pcs available, that should be more than enough for our scene.
No claims visible, so they seems all in a working condition (more than 20pcs bought in this year, and only positive feedbacks visible)
I have 3 dead Plus/4s, I think 2 of them is most probably due to 8501.
Maybe would be good to make a Group purchase, and spread it locally (within EU).
I would be happy to help in this action, though recently the postage from Hungary to abroad became extreme expensive.
BTW, do you think, it would fit?
