[GreenKeys] M15 How to disable unshift-on-space?

[WA5CAB--- via GreenKeys]

Sorry.  I assumed that you knew that the ceramic screw-in fuse holder was 
original to the machine.  Like you, I doubt that the fuse was originally 6 
Amp but there is no need to replace the holder, which seemed to be what you 
were about to do.  Also, many residential fuse boxes had cheaper bakelite fuse 
sockets in them.  Those do deteriorate sometimes, but not the ceramic ones 
unless they have been under water.

As to the correct (original) fuse value, I no longer have any of the dozen 
or so M15's I've owned over the years (sold the last pair of TG-7-B's about 
a month ago to Third Army) but the 3.2 Amp that someone reported does sound 
about right.  Bear in mind that the same machine might have any of about a 
dozen different motors installed, not just the synchronous 115 VAC 60 CPS 
ones in most machines running today.  For example, most of the Signal Corps 
machines had either AC or DC series governed motors with a built-in lamp for 
calibration.  A few machines had utility outlets installed.  So the motor 
wasn't the only thing that the fuse powered.
