Intel and Aox have recently released 386SX CPU upgrade modules for some 286
based computers. Both are small modules that plug into the existing 286 socket
(Aox's is 1.5"x1.5"x0.6" and Intel's is 5 sq. inches). Also, both have a 16KB
cache to compensate for the slow memory access and both support the 287 math
coprocessor.

Intel's SnapIn claims compatibility with the PS/2 models 50 & 60, however
additional support should be announced by the end of the year. The list
price for the SnapIn is $495 (around $370 mail order). Their benchmarks are
Norton SI of 21, 2.7 MIPS, 801.8K Whetstones and 3793 Drystones. They claim
a performance boost of 1.7 to 2.0. The SnapIn uses a 386SX-20MHz.

Aox's StaX claims compatibility with a fairly wide range of 286 PC's (includes
the PS/2 30-286, Compaq Deskpro 286, AST Bravo & Premium, HP Vectra, IBM AT and
some others). Two versions are available, a 386SX-16MHz ($279) and a
386SX-20MHz ($329 direct from Aox). Their benchmark figures are similar to the
ones for the Intel SnapIn. NSTL (National Software Testing Labs) tested the
StaX with a variety of software. They claim compatibility with all the major
386 memory managers (QEMM, 386MAX).

Usual disclaimer applies. I am not connected with any of the above mentioned
companies.
