Emax

Royce-
Yes that board is upgradable.

Instructions here for the modification:

I also have slim floppy converters available for $17.50.
This allows one to hook up a standard slim floppy drive.

Pics of slim floppy installed in emax here:

Hi Ted
I have a Emax I with the board
Version 2
revision C
There is no 5380
IC 13 is IP255
IC 49 is IP344

Can I upgrade my Emax?
Do you have kit left?
What wiring is needed?

Thanks
Royce
