well, I have the microvax III cpu in my ba123, because I got tired of the slow speed of the mvax II. I had to diddle with systartup, as it could not figure out my configuration, but it has been running for nearly 10 years that way. The mvax III cpu had the S handles, i took them off. I saw dialog on size limitations for hard drives on mvax II, perhaps only 2 gb possible? Anyway, I also use an Emulex QD01 to run a SCSI rewriteable optical drive, so there are other means of getting SCSI. Joe Heck
