The newer version of the CSS Lab's '386 system-board that is able
to be populated with up to four MB of RAM is known to run SCO Xenix 386 without 
any problem.  This is a good choice for users who want take advantage of the
increased clock rate (their 16 MHz system is switchable 20 MHz too!) and the 
linear address space, at a reasonable cost.  CSS Lab's makes a very 
reliable and well designed product.  Unfortunately, they are experiencing
difficulty obtaining 1 MB RAM chips.  As a result, they will only sell
their systems with a maximum of one MB of RAM installed, but as a temporary
measure you can use your old 16-bit RAM expansion card.
 
Users who can afford a to spend a little more should consider the purchase
of a system that supports RAM caching circuitry.  CSS is due to release
their new caching system-board this summer.  They won't reveal what
size the cache will be, but for multiuser/multitasking operating systems that 
will be running many processes (thus requiring a good deal of RAM), a
large cache (on the order of 256 K bytes) is superior to the 64 K 
RAM caches currently available on most '386 system boards.  

Everex is the only manufacturer I am aware of that offers caching 
circuitry of this size.  

Disclaimer: I am both a CSS Lab's and Everex dealer.  I don't sell
other than that in which I have complete confidence.
