The Sequel - Oh Blimey I bought a CNC Lathe (Beaver TC 20)

Well in this project, pre-determined is that the data lines are labelled 1-16 but the address lines are labelled 0-15, and even worse, the data line appear on pins with A(nn) numbering leading to all sorts of confusion.
However, personally I think things should be labelled as what they are! If labelling a class of four items as 1-3 and no label, you are stuck when label 2 falls off, and in the real world this happens all to often.

So I got the remaining rows 'B' & 'C' crimped and sleeved so now at last perhaps I can get down to proper testing!
WeldingRod:
That's easy! You label all four because that way you have a check sum ;-)
Otherwise, if your tape fails you have two identically "not labelled" parts...

Hi Andrew
I have to admire your enthusiasm and energy pursuing this fault finding "adventure"
In a previous life I worked as a spark and instrument tech at a combined cycle gas fired powered station
Seeing the multitude of connections on your "test rig" reminds me of my work back then
All long gone now (including me)!!
John
awemawson:
Thanks for your kind words John.
I don’t HAVE to do this but it keeps my brain working!
