The only 386 upgrades I know of are know by
the ID
-486 SLC propably a 386 SX replacement
-486 DLC a 386 DX (I dunno for sure)
They had extra cache and could run up to 40
or 50 Mhz with some internal
clock multiplication. Numerical coprocessors
were of the 387 type (Fastmath).

Souped up 386's so to speak

I've seen both on CPU-boards that looked very
much like
their 386SX /DX progenitors. Same types of
PLL oscilators, placement of
SIMMS (30pins) and slots and identical glue

It has been know tha not all software could
be run reliably on them.
