Yes, I did :-) It fits perfectly to a milimeter - the DIP32 Flash chip
on the upper board just touches the vent holes in the top cover. And
that is including DIP24 and DIP28 sockets soldered instead of the
original ROM chips.

The only downside is that the upper board must be moved about 3
centimeters towards the rear, so that it does not interfere with the
keyboard mounting. That means that the lower board must be bigger to
move the connectors in that direction. But then, it must be bigger
anyway to accommodate an additional 7400 chip that translates the CS
line of the ROM/KERNAL chip and its A13 line into proper KERNAL_CS and
BASIC_CS lines the upper board expects.
