Default Re: 8085 processor questions

I have to agree that in the past I have had real difficulty using a scope on the crystal as the capacitance of the probe stops it working. Scoping on other pins like clock out to the other ICs is a better indication. It has been many years since I worked with that micro (a bad experience during my degree project work) so can't help any further I'm sorry.
