I have been contacted by a fellow with an FR-38D/U digital counter, I
gather he would like to let it go.
This is a tube-based digital electronic counter, identical to the
HP-524B, but I think the particular unit at issue was actually
manufactured by Northeastern Engineering. (I've never understood the
relationship, but AIUI Northeastern manufactured/second-sourced some
HP designs.)
Here is a photo of the unit:

For more info about the models, here are my web pages about the 524B
and HP-520 instruments:

These things aren't computers of course, but they are some of the
last pieces of tube-based digital electronic instruments, i.e. the
same technology as the the 1st generation of electronic computers.
Marketing spiel: You're not likely to ever own a digital tube
computer, but you can own a digital tube counter.
I'm just helping to see it preserved, you can contact Travis below if
interested.
I get questions and expressions of interest in these instruments
every now-and-then due to my web pages, but I have no idea what sort
of dollar/market value to assign.
The location is Kansas City. They're over 100 lbs and you'd have to
be really enthused to have it shipped - so hopefully someone can pick
it up.
If someone obtains this unit, I can supply the schematic, at least
for the HP version. (I have a 524B and 524C that I have repaired.) If
someone does obtain it I'd be interested to hear about it.

Hi. I have this unit in the military version FR-38D/U. I'll provide
a pic. Do these have any value to collectors? Thank you.
