RE: Follow up 1084s question

Just a quick follow up note.

On my 1084S, it's pot R225, "H-HOLD" and according to my DMM, it's 30K.
I mounted a 25K pot (more than adequate) externally on the casing. Works
well. I can't always get Tron to sync up, but I am also using boards
that don't work 100%. Usually I can get close enough though.

I just ran a few lines through the plastic case and mounted it using a
bracket and a small bit of prototyping board.
