You are referring to the Intersil IM6100 processor "family".  5 to 10
volt CMOS, various speed grades from 4 to 8 MHz.  Originally appeared
about 1976; Harris second-sourced them and also came out with an
improved version, the 6120 (co-designed with DEC? ... cl will elaborate :-)

I rather doubt that either company makes these any more ... 'tis a shame.

I have a few myself, along with the companion chips: the 6102 MMU,
timer and DMA combo, the 6101 PIE (peripheral interface element: kind
of port decoder/timing controller), and some 6402 CMOS UARTs.  Sorry,
not for sale!  These'll either get built into my home-brew PDP8 project
that I started in 1977 (so it's been a long time coming, what about
that garage you promised yourself you'd clean out? sheesh!), or held
for their antique value.  When PDP8 architecture comes back into vogue,
and everyone wants one, I'll be able to sell these things and retire
comfortably.
