I wonder if
anyone here want to try to build tiny PDP-11 compatible computer using KM1801VM3B CPU.
This chip still available in small quantities (price range is $10...$35). The system could
use an microcontroller such as ATmega1284 and/or big CPLD to emulate all required
peripherals. There were systems using this chip, but unfortunately most of them contains
enough gold to became firstclass target for gold scrap hunters. So, it's very hard to
find working system today.
Here is related link:

...have three of them and some VM2 too. I where interested in such a
project. Currently I'm trying to build ans SBC out of an VM2 with some
old Tesla MVB1012 Chips (AY5-1013?) and a CPLD...
Are datasheets around for the K1801 chips?
