Multiface 128 help

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?

If you look at earlyer posts i have exactly the same problem, but now my
original eprom no longer works, i tried 27c(64,128 and 256) with no luck, is
there any chance that you could read your original eporm and send me a copy
to try on mine to see if i can get it to live again please.
