Hi!

As Oliver talked about a coldfire design that plugged into a 030
socket I wonder if it would be very complex to create a board similar
to the old X-Calibur board for A3640, that plugged between the 040 and
the A3640 and contained 128MB (soldered). There are thousands of A3640
boards out there that are almost useless because you can't fit more
than 16MB in the motherboard. I guess that with a small FPGA that
acted as memory controller for the 040 and a pair of 64MB DDR memory
chips it would be enough. If it didn't eat much space this could be
useful for old A2000/A500 memory boards... There are DDR memory
controller at opencores.org. I guess it would be possible too to
include a simple gfx card connected directly to the 040 bus (That
would provide a very fast bus to gfx ram), mapped to an unused memory
area (but that probably would be too much complex for such a tiny
board).
