Re: Z80 and SIO board running
Sorry, forgot the URL. Please send updates on your build progress to
S100computers.com or make a new page at the N8VEM wiki. New builders
will ask many of the same questions and experiences you are doing now
so recording your effort will help future builders.
Thanks and have a nice day!
