Re: ULA or ULA Replacement
Also this another one...
In my opinion both solutions are a little expensive, but if you think it is worthy... choose your preference...
Just an advice... better an ULA+![Smile :)](./images/smilies/icon_e_smile.gif)

Re: ULA or ULA Replacement
A ULA for which machine? For a ZX81 / TS1000 or for a ZX Spectrum?

There are four lights!
Step up to red alert. Sir, are you absolutely sure? It does mean changing the bulb
Looking forward to summer being good this year.

Topic changed. The ULA has to be for ZX81.

Re: ZX81 ULA or ULA Replacement
So, as far as I am aware, all stocks of the original ULA chips are sold out. Ian of Mutant Caterpillar may still have some, but will only fit them as a repair due to being unable to obtain new ULAs.
Your best bet is to obtain a vLA81 (see also the link in an earlier post).
Other than that, it’s a case of obtaining another ZX81 or TS1000 and using it as a donor machine.

The question was for a ULA for a ZX81, so neither ULA+ or Nebula ULA will work, as they are for ZX Spectrum.
