 Form? Contacts? terminal type?

   Yes: Let's postulate that your bucket is populated with a Generous
Quantity of 5V 6PDT relays with sockets. Look up the schematics /
articles for the Simon Relay Computer from (I think: others will please
correct me) a mid-50s issue of "Popular Electronics", or "Electronics
Illustrated", or maybe even "Better Homes and Electromechanical Brains",
or some such periodical... anyway these relays would make a dandy Simon,
or two, or perhaps a Simon with a Relay Floating Point Processor....

   If you use sockets and a PCB layout program like Eagle or ExpressPC -
you could even eliminate most of the tedious wiring - depends on just how
'authentic' you wanted to get.


Cheers
