Hi
Still, all this stuff is from NOS ( New-Old-Stock ) as well as
bits and pieces from various manufacture stock rooms.
The most common 8 bit still in regular manufacture today
would most likely be the 8051 stuff from Philips. It is a
ugly processor to use as a general purpose processor but
quite nice for things like microwave oven controls. Large
memory access ( 64K ) is a pain.
