Yes, I've no idea how many of these ones are still working - although given 
that they're intact on PCBs, my guess is that they're the result of 
board-swaps and so one or two digits/modules may be out (or there are other 
board faults) but the rest are still operational.

In total, not counting ones which physical damage or obviously-failed 
segments, I think I have around 20 each of dual and triple-digit ones, plus 
a handful of quads, which is enough to do something with while having a 
spares stock. Hopefully the pair of PSUs that I rescued are OK, as they've 
got handy 6V->180V DC convertor modules on them.
