Hi Victor. The problem is that there are no details at all for this
upgrade anywhere on the Web (as far as I know) other than the
installation instructions. It would be great to have a really good
square on picture of the front and rear of the board, so a track layout
could be drawn from it and the various coloured flying leads and links
traced to their pads. Chip details would be good too. Tricky to do
though as the daughter board is soldered in and can't be arranged flat
under the camera. A rom image of the 2.2 DFS would also be necessary as
it contains the memory management routines for the extra 64k.

-Neil.
