I recently picked up this piece of e-waste very cheap which was originally a piece of rackmountable broadcasting equipment that now is apparently obsolete. It is meant to display a bunch of different data relating to time code.
On its front it has a matrix of switches and this VERY nice looking, bright alphanumeric display, which I suspect may be a VFD behind a sheet of green plastic. It looks to me like a VFD.
Its either that or an LED.
Anyway, I would love to be able to remove the main circuit board completely and re-purpose the case and its display and low profile encapsulated toroid 12+5v power supply (and 9 BNCs and two DB9s on its rear panel) to use with my GPSDO.
Its not so visible in any of the pictures but the individual portions of the display alternate up and down in a particular way. Which suggests VFD tubes to me. I'll have to get some better pictures.
Does this suggest any particular display manufacturer?
I have to clean my desk and put down my ESD mat, before I go taking this apart further. The entire front panel looks as if it might be useful with fairly minor modification IF I can figure out how to talk to it.
Its probably a standard protocol, accessible via the IDC header which can be seen. I suppose I could insert my own pair of IDC connectors leading to a breakout board in between it and the PCB and sniff it with my logic analyzer, if I cant figure it out any other way.
