	You see, it goes like this:  I have 2 meg of 256k Simms lying around
and I would love to use them.  I know that there are SIMM boards available
(JRI, etc.) but I do not believe that any of them support 2 4-SIMM banks.  
Someone once wrote me saying they had managed to do a direct connect with the
SIMMs, with the exception of needing to buffer, I believe, the write-enable
line.  I would like to do basically the same thing, but I gotta know what 
Pin(x) is and where it should go.  Also, does anyone out there foresee problems
with doing this type of an upgrade?  I have a 520ST (version with the rf out)
so I know that space will be tight, and that I will probably be limited to 1
meg simply because of space considerations.  However, if I can do it, let me
know how.
	Also, if anyone could point out a few good, easily obtainable (If I 
can get it at the local bookstore, or at the campus one, this is GOOD) books
that might aid my quest for expanded memory - and the thrill of the hack!  
Something like: "the TI guide to Memory" which would include total specs on
simms in-use by Macs,etc.
