I recently purchased a table which looks very much like a "Harvard XP 1000" brand of a similar make of an "all-wood" look, but with some distinctive differences in the design (such as 4 drink holders instead of two.. rounded corners on table, one beveled corner on each leg, etc. )
It has two plates on either end of the table that say "tsi" in lower-case. No sign of "Harvard" on the table nor any sign of any other clues as to what manufacturer/brand it is. I'm not assuming it's a harvard table but it's the closest match on the net I could find.
I did a google search on "tsi foosball" and came up with nothing.
Any of you experts have an idea what it stands for?
