Well to sum it all up, long term project. started last summer so re-capping
what was done then and now. All of the RA-81's Look to have bad Tack
sensors. I don't have a working one to try. Thanks, Kevin for the input
helps confirm what I have been seeing.
The cable on the right is for the belt tension. The brake is part of the motor
most likely electric I would guess.
The service manual has the wiring wrong on the tack plug so be careful.
The print set for these on Bitsavers is missing pages that cover the Read/
Write board which is part of the tack system.
If anyone has a complete copy of the print set or knows where one is ??
Please let me Know.
Thanks, Jerry

well now I feel real dumb. I was looking for the drive locks
and could only find the head lock. Now I know the cable on
the right is *not* for belt tension. Thanks all
Henk, Is your 11/60 running

Hi Jerry,
the 11/60 is running - sort of ... The console works,
so the CPU is OK. But store/examine memory location
seem to indicates stuck bit(s) :-/
I just finished moving the collection to a 2150 sq. ft room
and found out that *many* systems need TLC.
The 11/60 is just one in the queue! I also want to work
on the website, but time flies ...
greetz,
