t TCP/IP stack for it, AND, it’s requirements are low enough to work well on a MicroVAX II. In fact it’s what I tend to prefer to run on VAXen. Having said that, I’d like to get a v4.x system up and running at some point. My MicroVAX III was running 4.something when I got it. I booted it up

Re: MicroVax II

Hi Doug, I've used an SCSI2SD v5 in a Symbolics XL1201 as both CD-ROM and 1280-byte sector Hard Drive mode successfully. I don't know anything about a MicroVax II, but I would be happy to tell you what I know of the SCSI2SD. (I've actually put several in one computer simultaneously.) Cheers
