No more bus driver discussion, PLEASE!

That doesn't mean the boards worked in multiple-cabinet arrangements. At Software Results, we paid the big bucks and used real DEC DC013s and DC005s and Natl Semi 8641s, etc., in all our products. We were already a 3rd-party product and didn't need any fingers pointed at us when things didn't work right (the only issue I ever remember was related to bus timeout issues in the last Qbus VAXen that had a DLT drive on a particular DEC controller - our board wasn't tolerant enough of the SCSI controller holding the bus longer than any other DEC product). We certainly didn't want to play the game of "it doesn't work - must be your random bus drivers causing it" and having to prove it right or wrong. Speaking for myself, I read each and every message on this list as it relates to classic DEC busses and how to make modern peripherals for them. I don't always have a comment to make, but I read each and every one to see if we've found a way to make "in spec" peripherals. Carry on -ethan
