Or the jumper headers. Even the famous "0-ohm" resistors (a wire with a fake resistor body with a single black band on it). Remember the "/phantom" line (pin 67) to tri-state memory boards so the PROM would present itself, overlying any RAM at that address? BTW, I used to work for Micropolis back in the 70's. I was employee 22 there. Yes, I'm an old fart. Oh my, a trip down memory (or UVEPROM/EEPROM) lane! ---------------------------------------------------------------------- - Rick Stevens, Systems Engineer, AllDigital ri...@alldigital.com - - AIM/Skype: therps2 ICQ: 226437340 Yahoo: origrps2 - - - - Polygon: A dead parrot (With apologies to John Cleese) - ---------------------------------------------------------------------- _______________________________________________ users mailing list -- users@lists.fedoraproject.org To unsubscribe send an email to users-le...@lists.fedoraproject.org Fedora Code of Conduct: https://getfedora.org/code-of-conduct.html List Guidelines: https://fedoraproject.org/wiki/Mailing_list_guidelines List Archives: https://lists.fedoraproject.org/archives/list/users@lists.fedoraproject.org
