Hi,
I realise that this is a pretty difficult question to answer, but I'll try anyway......
I am building a Z80 based computer, with 0.1" pitch Eurocard sized boards connected to a DIN 41612 backplane. I am hand soldering it and am looking to get an idea of what a realistic clock speed might be. I have put 0.1uF decoupling capacitors close to all of the ICs and a bulk decoupling capacitor on the board. There are no power & ground planes on this type of board - so all of the connections are wired.
I have not found anything on the web that gives any indication of what I might expect, other than quotes such as "a few megahertz" - whatever that might mean. I am 20MHz CPU, but won't be aiming for that, I'd just like an indication of what I might be able to achieve.
So, based on your previous experience of this type of construction, what do you think would be a reasonable target clock speed to aim for?
regards
Dave
