Thanks for finding that I have never been able to find it myself. I am
slowly translating from the German. My card has the riser below and then
two chips sitting one on top of the other with a piece of sponge black
Velcro stuck to the top. I had no idea how this card would have fit in
the C64 but I see they put a spacer on the main body case
This project deals with the reproduction of the '4x4 extension' for the
C64 from c't Magazine issue 6 of 1987, page 94, article "Aufgemacht: C64
with 4 MHz clock and 16-bit CPU" by the authors Michael Flamm and Rene
Schneider.
This is a performance-enhancing extension for the C64, which must be
installed in the C64. The original 6510 processor is taken out and
replaced by a 15x15cm board with a 65816 processor and 256Kbyte
additional RAM and lots of other logic ICs. To be 100% downwards
compatible, you can switch off everything by software. There is also the
base for the 6510 on the board, it will be active and everything else
will be deactivated.
Thanks for looking for me
