Kind regards,

Thanks for the "trusty supplier". Indeed my woodstock replacement LED modules are still available and ready for "plug and play".

The digits have a slightly different appearance than the originals, because they are about 15% smaller in size (45 mm instead of 54mm). And due to the higher components they are finally located nearer to the red display cover. But they are a real replacement, and the only one that I know of, in case that you have to fix a defective woodstock display.

Unfortunately I cannot sell them for 16$, because my cost were about 22$ each, 12 alone for buying the LED modules. But shipping without insurance could be reduced to 2$.

I tried to build also a replacement for spice series calculators, but didn't make it yet, you need to build your own adapter. For pinout description see attachement.
