**TACT82S411  Snake+ Single-Chip AT Controller [no datasheet]      c91
***Notes:
from: 
http://www.cbronline.com/news/ti_announces_the_tact82s411_chip_implementation/

"Texas Instruments Inc has announced the TACT82S411, a new single chip
implementation of all the support  circuitry surrounding the CPU in an
AT-alike, operating at  up to 20MHz for 80286  and 80386SX laptops and
notebooks:  the  new  chip   will  integrate  system  logic  and  most
peripheral  functions,  including   interrupt  controller,  timer  and
real-time clock, so that only  seven logic devices, as well as memory,
processor  and math  co-processor are  needed  on a  80286 or  80386SX
motherboard;  the  chip  features  128-byte  CMOS  configuration  RAM,
two-way and  four-way page interleave  mode with 64Kb, 256Kb,  1Mb and
4Mb dynamic  RAM, and support for  up to 32Mb  memory; sampling starts
this month, with volume in the fourth quarter. "
