Out of interest what did you use to replace the roller and where did you get it from? I have a TU58 and both rollers have become brittle and cracked so I need to replace them. Any advice on a replacement would be very useful! Thanks, Toby -- This message has been scanned for viruses and dangerous content by MailScanner, and is believed to be clean.

I haven't fired mine up in years, but more discussion on the list about them will certainly motivate me to do so. I often muse about what to do about disk, though. The last time I powered an 11/750 up, it had an SI9900 w/two SMD disks, and a UDA50 w/RA81. I kinda don't mind the 800-1000W of the CPU, but three 14" disks get expensive to keep turning (as I've posted before - nearly a gig of storage on this machine *20 years ago* - all bought new in the early-to-mid 1980s for around $50,000) Cool. Agreed. My first experiences with VMS and UNIX was on my 11/750 in 1984. I was quite happy to be able to save it when the company closed ten years later. In our heyday, we had dozens of users on this box, and it was quite responsive as long as we didn't have too many people sitting around idle in MASS-11 and VMS MAIL (those were our highest memory-using apps - more than about 20 users in them, idle or not, and we started paging and swapping). After the company went through a couple of rounds of downsizing, there would be frequent times that there were only 3 active users on the machine - it was downright peppy then. Even into the mid-1990s, it was a nice single-user machine. The only other machine we had that could touch it was a MicroVAX-II, but that was less fun as a software development platform because despite a CPU that was easily 50% faster, and 12.5% more memory, the disk performance difference between Qbus MFM disk (RD53/RQDX3) and MASSBUS disk really came out during compiles. At some point I'm going to have to finish my plans to mount a 5.25" disk of some type (ESDI, SMD, SDI...) inside a 11/750 for a single-cabinet system. At its maximum extent, ours spanned 5 cabinets full-time (CPU, TU80+BA11, SI9900+SMD disk+BA11, TU78, 80-port patch rack), and occasionally reached out to an RA81 on our 8200 via the B-port (so we could back the drive up and move massive amounts of files quickly) Nice, but more space than I have at home (and I couldn't recreate the original configuration now since the TU78 was not rescued with the CPU, way back when). Dave, if you have any 11/750 questions, I'll do my best to help. Since it was my introduction to the VAX, I've always had a place in my heart for them and I love to see them still kicking. -ethan
