3 bit × 10 bit multiply

 Probably the second easiest bit of circuitry...


Here we have 7 × 3FF = 1BF9.


Here we have 3 × 61 = 0123.

6 bit ÷ ten (decimal) revisited

Hand soldering of the IDC connectors is proving too fiddly (when constructing the 3 bit × 10 bit multiplier board - see next post), so I've opted to use D-sub connectors, fixed to an aluminium cross piece:


The D-subs are fixed to the cross piece using Richco, PCB MB 01 mounting blocks and M3 self tappers. The cross piece is fixed to the rail pieces using Richco HTSB M3-9-5-2 9 mm threaded standoffs. 


I like this approach - looking mainframe-esque:
