C80286-6 I326001S ES (c) INTEL '82

The C80286 was introduced in February 1982. It used a pineless 68-pad Ceramic LCC (LeadLess Chip Carrier) package. Intel originally released 8 and 10 MHz parts. 6 and 4 MHz came later, as less-expensive options. This engineering sample was built in June 1983, before the official launch of the C80286-6.
