Albert, this IS Mount Everest (of NBTV anyway)
I think I may wait until the PCB version comes out.
(or a cheap 32x48 matrix module becomes available
Oh, and my version would HAVE to have a commutator (just kidding).
In 1986 I designed and built ON veroboard (what was I thinking? - oh well I was young and naive - about the same age as Julia Gillard was and she uses that excuse and gets away with it - so far) the attached schematic.
It was a kind of forerunner to todays MP3 player (but using continuosly variable slope delta modulation) intended to help disabled people communicate with their rehabilitation officers.
It worked - but eventually I needed the Universities logic analyser and/or storage cro to debug just a tiny little timing glitch in the serial to parallel converter. Otherwise it was kitchen table engineering. I looked this up because I thought I might have used 4017s somewhere but apparently not.
So I have an idea what you are going through Albert.
I have seen more complicated (NBTV even) circuits built on vero board but this is the most complicated circuit I have built using that technique. Other than the power supply this was built on one board. The RAM bus was a nightmare...
BTW this was drawn on an early version of autocad but I appear to have lost an electronic copy.
I attach a full copy of a HD image of the schematic in case anyone wants to peruse the circuit in detail.
