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 !

Best regards, Steven C  KJ6STF
