It all boils down to noise margins. High voltage (tube) digital circuits enjoy extremely wide noise margins, so most electrical crap can be safely ignored. There were lots of other issues with tube digital that made design "fun", but that can wait... -- Will ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to [EMAIL PROTECTED] with the message: GET IBM-MAIN INFO Search the archives at http://bama.ua.edu/archives/ibm-main.html
