**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.
