I had the original boxed set with all sorts of add-on book such as "High
Guard" and others.   In the MegaTraveller line I had all of them as well.

With the exception of World Builder's Handbook, MT Player's Handbook and
Imperial Encyclopedia the entire collection is now missing as a side
effect of us moving in March.    Pretty sure they are permanently
missing.

The one I care about the most is the MT Referee's Handbook which I
horsed up with all the addendums.

My first question is, can I find the MT Referee's Handbook on sale as a
reprint or something darn near like it?

I'd like to get back on track with developing my sector generator
program now that I'm settled in.  Do just the star system generation
tables exist on line somewhere?
