KVI) Newsgroups: mod.computers.vax Subject: Q18 to Q22 bus conversion Message-ID: <8701061005.AA26707@ucbvax.Berkeley.EDU> Date: Tue, 6-Jan-87 02:54:00 EST Article-I.D.: ucbvax.8701061005.AA26707 Posted: Tue Jan 6 02:54:00 1987 Date-Received: Tue, 6-Jan-87 19:32:34 EST Sender: daemon@ucbvax.BERKELEY.EDU Organization: The ARPA Internet Lines: 15 Approved: info-vax@sri-kl.arpa Their is a rumour that the difference between an 18-bits and a 22-bits Q-bus backplane is just a matter of adding 4 wirewrap wires. Is this true and is there anyone out there who has succesfully performed this "upgrade"? I realize that there is probably a better bulletin topic for this problem but I don't have an overview of all the topics. If anyone could suggest a better topic for this problem to post this message please let me know (INFO-RSX? INFO-QBUS? INFO-PDP, INFO-ANTIQUE?) +----------------------KVI----------+--------------------------------------+ | Peter A.
