The LCM had a beautiful one in pretty advanced phases of restoration. They had 
replaced the supplies with modern ones. It’s pretty spectacular steampunk 
machine!

In the G15 programming manual at 
http://www.mirrorservice.org/sites/www.bitsavers.org/pdf/bendix/g-15/G15D_Programmers_Ref_Man.pdf
, there's a remark about sexagesimal digits. 
The manual says "usually hex in conversation because nobody wants to
abbreviate sex."
"The symbols in the sexagesimal language are u, v, w, x, y and z. These
are arbitrary markings; other computers may use different alphabetic
characters for these last six digits."
We're all familiar with A-F. The Illiac-I used KSNJFL because the input
device was a 5-bit Baudot-code teletype, and in "figs" mode they
produced those six binary patterns.
There were two mnemonics to remember those digits.

G15 was called the "First Personal Computer" because Bendix gave one to
Harry Huskey, who had designed it. He was also a professor at UC
Berkeley.

The Computer History Museum in Mountain View, CA has one, but it's not
in operating order.I don't know whether they have a mag tape drive.

G-15 was the first machine I used, at the Summer Science Program, in
Ojai, CA in 1963. We used it to calculate asteroid positions on
photographic plates, prior to computing orbit elements -- which we did
by hand on Monroe and Friden calculators.

Several years ago, I wrote an emulator for Intercom-1000. It's at 
http://vandyke.mynetgear.com/1401/G15.

UCLA used at least one G15 to syntax check Fortran programs before they
were submitted to the 7094.

Highway departments used them for years because Bendix provided cut-
and-cover software. The software might have been developed by a highway
department in Australia.

This was the machine I learned to program on.  (What was then Humble
Oil & Refining donated it to my high school.  I was the only student
curious enough to work on it.)

I still have one of each of the vaccum tube plugin cards.

Oh, and a copy of the technical manual with the FE's notes :-)

The last time I tried to gather together information about it (see
URL below), there were four still known.  Even as late at 20 years
ago there had been others, at McGill University in Canada, and one
in Australia:

I'm not either.  I have never seen that before.

I hope so too.  I'm not at the stage of my life where I could take on
this task.  But I would be glad to assist anyone actually working on one.

Business purposes?  No WAY!  The G-15 was obsolete within a 
year after it was introduced, but it was cheap, and for a 
few years core memory was still very expensive.  The 
performance was laughable by 1965 for sure.  They've had it 
for 25+ years?  How about FIFTY?


As for that rack on the right, it may be that they replaced 
the rather crude power supplies inside the

CPU with external regulated supplies.

It can be debated of the price for the Bendix is high or not, but it is truly a 
nice
and rare machine. And by the looks of it, it seems to be complete too.
Not sure tough if the rack on the right belongs to it.

I hope it ends up in a proper museum and hopefully it can be displayed in 
running condition.

so for these

https://www.ebay.co.uk/itm/203239181341

&

https://www.ebay.co.uk/itm/203239156838

usually works. You should be able to use any country specific e-bay, the 
numbers are global.
