I'm that 'other guy' :)
It seems that you are 'the other guy' on a lot of realy
nice stuff (BTW: Servus Christian).
(Ya, Servus Hans! Vie gehts?)
Well, you are also 'the other guy' based on several items I had seen last
year when you and Christine stopped by our house on the way to California
(and VCF).
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 :)
This could be a good definition to begin on. But, even then, many, many
other additional factors and opinions can come into play on defining
'rare'. So I just don't worry about it. Let's just say that I'm
thankful I
do have some 'rather uncommon' computers, radios, TVs and books in my
collections.

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.
Yes, existing programs are very important to preserve in this case. I just
had only one on my tape which I printed out. Just by seeing the program
source I got many insights into how to do _some_ programming without having
a manual. Your programs, by their quantity, may have many other methods and
syntactical suggestions which will help us understand more fully the
language the Tek 31's use. Depends upon the original programmer and how
resourceful he/she was.
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...
I would certainly consider coming but only if I get a decent paying job.
Still none to find yet in this backwater town. I'm working on alternative
carreer(s) at the moment.
Regards, Chris
