Unfortunately there is no replacement like ULAplus for the black +2A/+2B/+3 ZX Spectrum, only very rare original Amstrad ULA 40077. I have kept the spare NOS - new old stock one but lasti piece only. So I can sell it for 100 EUR only including tracked letter shipping to the UK. And I will missit when I will get a faulty black +2 or +3, because nobody is selling such ULAs anymore. Or I can offer to buy the +3 from you for 40GBP plus 30GBP shipping to Slovakia, EU and I will pay import charges myself. If the condition of the +3 is good, includes PSU and only fault item is 40077 chip. And you can buy the working +3 then.
