Just a novice question here..  I would like to build a parallel 
printer buffer.  I have several megs in 64k memory chips and would
love to build a nice buffer as a project.  I really would rather build
a 256k buffer (Don't ask why so large) but don't want to wire that
many 64k chips together! :-)  Maybe I could use two 1Meg chips and
store one nibble in each chip?

Would static ram be easier to implement?  If so are the prices
inhibitive?

The biggest thing I want to do is get the fastest turn-around on
the parallel line from the host.  Hopefully the design will allow
the host to burst the output without using interrupts. (This is a
Xenix System) 

So, the big question.. Where can I find some designs that would
be useful or even just manuals I can use to piece it all together.

Any input would be helpful.. Just would like to avoid the normal
liquid nitrogen comments.. ;-)
