Multiface 128

I bought an Multiface 128 off ebay, missing the label.
It works with the 128 but I think it is an early version because it
doesn't work with my +D connected, when I press the button it crashes
the 128.
The PC board revision on my MF is 34 and the EPROM version is 87.1.
I burned a new EPROM using an 87.2 ROM I found on the net but it doesn't
work at all.
Is there any information on how to re-wire the MF to use IN and OUT
Ports $BF $3F?
Any schematics of the various versions of the MF128 or good pictures of
the PC board, with components removed?

The problem is that the Multiface should be connected 'after' the plus
D, since the plus D doesnt have a pass trough connector your stuck, i
dont know if you be able to use a connector doubler cutting a track to
simulate the 'connecteds after'

Thanks for the reply. If I try a doubler what trace would I need to cut?
Another thing I have discovered is my Multiface doesn't work on my 48K
spectrum. I thought I had read the Multiface 128 also worked on the 48k

It should. It might just be corrosion and/or wear the edge connector.
My MF128 doesn't work on my speccy 128 anymore due to edge connector wear.
