**SL9XXX   FlexSet family General information
The SL9XXX series seems to have  been designed to work with the 80286,
80386SX and 80386DX, and is  possibly compatible with the 80486. What-
ever CPU used, the chipset  contains the following chips, known as the
"Core AT Logic chips":

SL9011 System  Controller
SL9020 Data Controller (2x for 32bit 386DX)
SL9025 Address Controller
SL9030 Integrated Peripheral Controller

The memory  controller is then selected  based on the  CPU. It appears
that the lineup originally consisted  of the following chips, known as
"Personalized AT Logic":
SL9151 Page Interleave Memory      (80286)
SL9250 Memory Controller           (80386SX)
SL9350 Page Mode Memory Controller (80386DX)

Later updates were:
SL9251   Page Interleave Memory Controller (80386SX)
SL9351   Page Interleave Memory Controller (80386DX)

Further updates were:
SL9252   System and Memory Controller (80386SX)
SL9352   System and Memory Controller (80386DX)

As far  as i can  tell, these chips  only require the addition  of the
SL9020, or  2x in  the case  of the SL9352.  The datasheets  are quite
terse.

These parts and the whole design of the datasheets are very similar to
the chipsets released by Logicstar. I, however, cannot find any record
of a link between the companies. See *Logicstar for details.
