Is your M12 working??

I'm looking a the M12 schematic, fig 2.2a1, in Kretzman's RTTY Handbook. 
Am I correct that you need a separate 110VDC, _260 ma_ supply just for 
the selector magnets (separate from the loop supply)?

The unit we have has a new terminal strip with new wiring and about the 
right number of terminals, so I am assuming (hoping!) it is wired 
similar to fig 2.2a1. (unit is at the Museum, so I won't get to play 
with it again until Tuesday.)

What holds the paper roll? Is it mounted on the cover? (I don't have the 
cover.)  There was a sheet-metal u-bracket mounted to the inside of the 
table.  It was falling off, so I removed it.  But now I am thinking 
maybe its purpose was to hold the paper roll!  (I think that I can 
"borrow" a bracket from a M26.)

Doug - we are practically neighbors!  Have you ever been to the AWA 
Museum??  We have lots of TTYs (besides wireless equipment).  Come over 
some time & I give you a personal tour!

Thanks & have fun,
