I believe I have discovered
the cause of the skip to infinity bug.
It is software. It seems the system
sometimes transfers a junk comand to the
control. See me for details.

LPT stops for no obvious reason
sometimes with LOW PAPER ALERT on.
I kicked it a couple of times & it's fine
now.

Found mag tape "skip to infinity"
bug. Extra wire from
3825V ([?] cm sef) to 3824V in 516
input to CONO 220. Set. Removed
wire. Works now. Effect was
to strobe current contents
of IO buss into command hold
buffer when skip to EOF went away.
(i.e. it saw an EOF). SRR
