i guess i should add my two bits :-)
	i expanded memory in my 1040 using a John Russell Innovations
SIMMS based expansion board. the board lets you use either 1M Simms or
256K Simms, but you cannot mix them. There are four Simm sockets on
the board, and you can populate either 2 or all 4 sockets. It will
accomodate either the x8 or the x9 Simms (they can be 80ns, 100ns or
120ns simms, 150's will work too,but are not recommended, and are hard
to find in any case). An additional feature of this board is that it
comes with sockets for two shifters. you pull the existing shifter out
of its socket and install it in one of the sockets on the board. you
can optionally buy a second shifter, and plug it into the second
sockets for an expanded pallette (the board comes with software to
support the JRI 4096 color technology).

installation is quite easy if you are the handy type (6 solder points
and two headers, took about 30 min total). it fits (very snug) under
the shield (low profile SIMMS are *really* required for this). i have
had the board in for over a month, and its been doing great. to me it
made a lot of sense to use Simms instead of discrete chips, as they
can easily be re-used or moved to other machines, including future
atari ones. (they are quite cheap too now -- $85-90/1M Simm -- look at
the ads in computer shopper).

JRI can be reached at:
