Paul,
 
	I dunno about 10+ MHz, but a friend found 2M memory boards in a
HUG (Heath Users Group) magazine for $549 assembled or $300 without
memory chips.  You could probably add your own memory chips if you
needed higher speeds than it does.  Part of the price differential
is that IBM PC memory is dynamic and S-100 memory (the good stuff
anyway) is static.  Just check out the prices for the static rams
(chips only) sometime....
 
	I'll probably be getting one of these boards when my budget
recouperates from my ADIT purchase, so I can have a 2M RAM disk
for my SYSTEM: device, though any other suggestions are welcome.
I'll get you the name and number of the company above if you are
interested.

Does anyone else have any preferences for S-100 memory?  I think I'd like
to stick with static, too, but that tends to get expensive.  I'm going to
need at least 2M of RAM disk, using Macrotech VRAM boards would be around
$3200, a bit out of my price range....   :+)
