Hello from 2009 year :)
I made this machine long time ago, using schematic from a book "Radioelectronic toys" wroted by Stanisław Wojciechowski

This device can Add and Substract two 4-bit numbers and Multiply 3-bit by 2-bit numbers.

USSR relay 27 x RES22 and 16 x REK23 were used

Yep, it's looks like a piece of shit, but it work!
