Systron Donner 8350 Reader/Generator

Here's a lousy shot of my Nixie tube timecode generator/reader:

Click for a much better view!
I'm not sure what tubes are in it but the envelopes are only about 2" high. The thumbwheels set the starting time for generator mode so it can be used as a Nixie clock. The entire case is only one unit high.

Note the two missing keycaps between "Hold" and "Power". The plastic has become so brittle that the ears snapped like twigs with I pulled them off to replace the light bulbs. Not only does it look stupid but without the caps in place the switches can't be actuated.

I saved the pieces. I suppose they could be glued back together with a thin, springy piece of steel reinforcing the joint and making it flexible enough for them to be put back on again.

If I had new, blank caps I could reproduce the text with decals. If anyone has a fix please message me.

Perhaps later I'll have time to take a better picture and get some interior shots. And get the part numbers on the tubes.
