any interest

Always interested in new tubes for clocks.
here is the data sheet link.

These are the same glass diameter as the common B-5092/8421 nixies (not as
tall), but instead have a circle of 10 digits on the face, 0-9 clockwise, with
zero at the top.
Unlike Nixies, more than one digit can be on at the same time (if cathode
resistors are used, rather than a common anode resistor). They need only
+150VDC, and very little current. The digit is small, but the appearance is
very interesting, like a Dekatron, but with digits rather than dots. I don't
ever recall seeing them used in any commercial gear, but presumably they did
appear someplace, maybe another list member has that info. They can be used as
status displays to show up to 10 data items at the same time. They can almost
be used as a single tube for hours as well, because two digits can be on at one
time (1+0 to show 10, but NOT 1+1 to show 11, 1+2 to show 12, for example), a
novel and more clock-face-like appearance, but not really ideal.
The base is a non-standard 13 pin (3 center pins, outer circle of 10), so I
have no hope for sockets, but clearly loose pins will work fine to a PCB.
Because the numbers appear to race around the outer diameter of the tube when
cycled, they would provide very attractive seconds/minutes displays in clocks.
Driving is dead simple, ground the cathode to light, just as with regular
Nixies, but less current is required (larger resistor). Because more than one
can be on at a time, fading is possible to enhance motion. There are also
simliar tubes from Philips in europe, but their drive is quite complex, and
they are not interchangeable with these.
Anyway, I will have them posted up to Sphere Research shortly, or you can
just email me for more details. I have the factory data sheet as well, and I
will email the PDF to anybody interested. They will be quite cheap, but
there's only this one single batch available, no more stock after this, and
frankly I was surprised to get these. The appearance of this batch is excellent.
all the best,
