Re: [N8VEM-S100:882] S-100 Serial I/O Board Oscillator Frequency -- Incorrect?

[John Monahan <mon...@vitasoft.org>]

I made an entry on the web site (bottom of page) . Andrew would have to find the original .pdf file to correct schematic. Will put on list! 

In general people building any of these boards should look at the bottom the appropriate web page before starting for the latest corrections, updates, software, vender suggestions etc. That area will always contain the most current info. Also if you could use the S100computers forum that will get "issues" out to a broader group.

Thanks BTW for pointing the error out
