Hi Adrian , I'm certain I have a couple 8085s you can have for the shipping . Let me go through my storage unit this week end and find them . I'm in San Diego , CA USA , there has to be some slick way to ship to the UK to avoid all the unpleasantness .... Do you have PayPal or .... ? We can figure something out . You do know the 8085 has a MINIMUM frequency of 500 KHz due to internal dynamic logic ? It gets real pissy if you go below that . CDP1802s you can clock down to 0 Hz . Let me know if this will work for you . Happy Turkey Day !
