well, for anyone interested:
i came across a nice web-site with a bunch of old computers. The owner, John Davin
(anyone know this guy?) is selling all of his stuff.  He, too, has a
grey(off-white?) Tek31 on there.  Also on his list are a big blue Intel computer
(no name on site) some old Heathkit items and many others (about 85 total).  his
site is here:  
Its a pretty interesting site, not too much information about the computers but
nice pictures.

  I'm that 'other guy' :) 
 It seems that you are 'the other guy' on a lot of realy
 nice stuff (BTW: Servus Christian).
  The speculation that these are
'extremely' rare
 could be right on the money but until we beat the bushes enough to know for
 sure I defer use of that modifier 'EXTREMELY' to the background.  My sense
 is that this type of tool was not used by the 'normal' high end scientific
 calculator user, except maybe occasionally in a university math/science
 department, but rather by folks who needed a machine/test station
 controller with fancy calculating ability. Other high end electronic
 calculators typically from HP, Olivetti, Friden, Wang, etc. were more
 popular it seems. I would imagine not a whole heap of TEK 31's were sold
 (cost vs. utility?) and those that were may have been scrapped with the
 equipment they were built into or otherwise attached to. Or else something
 broke on them (tape drive my first guess.) 
 Sounds reasonable, as always, rare is relative - I assume,
 for most devices, only those who have been manufactured only
 within less than 500 pcs are realy rare - or a find with any
 old stuff originaly packed :)
  I have only one tape which came with the unit.
  Anyway, I would be interested in getting one
 or more extra tapes for my unit as the one I've got looks rather 'well used'.
 As Sellam already said - if there are duplicates within
 our box, or empty tapes, they are available for trade.
 In fact I have no idea whats on (it looks like some kind
 of audio analysis stuff), but I just don't want to loose
 any one of the programms.
 And for the ride to VCF, why don't you east coast guys
 join and buy some kind of group ticket for plane or
 Amtrak ? Or jut rent a Van ? 3 days driving (lets make
 this 5 days, including some dumpsters to dive :), great
 talks _and_ enough space for the 'small' findings at VCF...

 BTW: Sallam, did you pick up the other EQ ?
