A VFD display for a buck.  I have already figured out the pinouts for these LEDs, all work fine.  The X/O display has two segments for the X's (/ and \) and four for the O's (N, S, E, and W crescents.)   Everything I tried worked.  Haven't done the VFD yet but they look like they are new condition, never used.

I like those 3-digit 7-segment displays.  I'd buy a dozen just to have handy.

Not so sure about the X-in-O displays.

I bought (left to right) 10, 10, 5, 5, mostly on account of how little they all cost.

That was what I was thinking but there is a practical problem with the displays being 2x1 instead of 3x1 which is there is no possible way to fit them into a 3x3 board, so I guess you go with a 4x4 board which is less common around here.  One possibility could be that each move is half an O or half an X because the segments are evenly divisible but I am not sure if that would make the game better or worse.

I am even more interested in that VFD.  I forgot that the filament driver is usually low voltage AC so I have to make a power supply to do that and start testing it out.

The "XO" displays could make an interesting binary clock display: use the crescents for the low-order 4 bits, and the bars for the 3 high-order ones.

You could also use them to make an animated gauge by "spinning" it at a variable rate to show magnitude.
