I thought, I was heading in the right direction, but to my discovery went making the final connections to the tortoise switch machine. I develop a feed-back problem that lid up all the LED for a particular route into staging. On further study I determine my error, the diode-matrix board is wrong and how I wired the rotary selector switches are all wrong, so back to the start.
I have presently two path:
1) Re-wire selector switches, make a new diode-matrix board and build a proper power source.
2) I am investigate another approach, see David K. Smith clinic Matrix Control for Tortoise Switch Machines
More to come.................
