I am pretty sure I have the first print of that manual, but I thought
Datamatic was a pre-Burroughs machine not Honeywell...I am not home to
check, if you'd like me to I can Monday.  That's the base 10 system,
right?  I also have some orig decimal counter tubes IIRC too.  I suppose
that all qualifies as pretty rare.  Or I am confusing with a different,
similarly - named system.
