Message-ID: <12098@watcgl.waterloo.edu> Date: 27 Oct 89 03:31:22 GMT Sender: idallen@watcgl.waterloo.edu Reply-To: idallen@watcgl.waterloo.edu Distribution: comp Lines: 13 From: "Ian! D. Allen [CGL]" We have an 8600 running 4.3bsd with a DMF-32 (2 modem-control serial lines, 6 dumb serial lines, parallel port) and two DMZ-32's (two times 24 modem-control serial lines). (I moved two of our telebit modems over to the DMF after I found out that the DMZ just could not do 19.2kbps.) I went DEC catalogue (catalog) shopping for serial lines for the replacement DECsystem 5810 we are considering (VAXBI bus), and was amazed at how expensive things are -- about three times the price-per-port of a Q-bus serial controller. I think I'm going to buy a Q-bus serial controller for each of our MVII and VS3200 Q-bus machines instead. Why are these VAXBI serial controllers so expensive?
