Hi @PhilC Sorry the @mention grabbed the wrong Phil. ;)
I will follow your lead. I have an Atari Floppy so I may skip the pullups. Floppy works fine now.
Was my stack of board/socket/tos decoder/socket/tf536 the same as yours?
TY for the hint of using the diag card with a 68K in the system first. I'll do that between steps!

@tony.reynolds yes the stack is how I did mine.

You'll need to connect the wire from the decoder board to the ce pin on the dual tos board.
If it ain't broke, test it to Destruction.

Right on, @PhilC

The attic is finally cool enough to work up there for about an hour.
This week:
  • I soldered on all the headers on my MiST HW. No sense in being caught out.
  • I recapped the MegaST's P/S yesterday and I had great success. It was fine practice with the Hakko desolderer. I'll do some more work off my soldering list and desoldering list before I do the SIP resistor pack replacements on my MegaST board itself.
