ZX Spectrum ULA gallery

I decided to create this ULA gallery to give people a look at the timeline of probably the most important part of the ZX Spectrum.
It’s in chronological order that should give the best impression.

I will update this list with photos you guys send me: send your ULA photos to: ula@bytedelight.com.
And if you are able to dig into these details (but if not, please send me just your ULA photos!), please add info like:

  • what board it’s in
  • general temperature after 15 minutes (outside case)
  • hotspot temperature after 15 minutes (outside case)
  • other technical details

More webpages about the ZX Spectrum ULA:

There are probably errors on this page. If you find any, please let me know: ula@bytedelight.com.
