I have a number of SMD and ESDI controllers for workstations and minicomputers. In particular, ESDI and SMD for Qbus, in multiple SI9900 boxes (MASSBUS-SMD), and in an oddball 3rd-party box with a dual SDI-ESDI interface (with a pair of working 600MB drives, at least the last time I powered it on). It would be fantastic to hang emulated drives off the boards I have. Looking forward to the eventual launch! -ethan

Re: SMD disks
With SMD disks even harder to come by than MFM disks, has there been any plug-in replacements developed for them? I've seen MFM disk emulators, haven't seen SMD ones though, anyone know if they exist?

After a bit of cleaning, they both worked fine, formatting and checking was successful. In my experience, the 8" Fujitsu SMD drives are rock-solid, all of my drives work, never had issues, even after years of storage. It's a very different story with the 10.5" Fujitsu Super Eagles... Talking about such drives, did anybody ever come across some manuals for the Super Eages M2361A? There are M2351 Eagle manuals online, but not for the Super Eagles which are different. Never came across a paper version, either. Best regards, Pierre

I can't remember now if the Xylogics 7053 did the same thing with split Command cables. I assume that in the disk cabinet the two Command In connectors join back into a standard 60-pin SMD Control connection to the first disk, which is then chained to the second disk, which is the chained and split again to the two Command Out connectors. >

From a quick look online the Xylogics 7053 SMD controller has a CMD port, and a DATA 0,1 and a DATA 2,3 port. If I remember right the CMD port was cabled to the CMD in port of the first drive, then the CMD out port of the first drive was cabled to the CMD in port of the second drive, then the CMD out port of the second drive was terminated. The DATA 0,1 port must have had a Y-cable that was split to the DATA ports of each drive. On the controller side, there are two command connectors, one wider than the other, as well as two data connectors. On the disk cabinet side, there is a connector marked 'data 0', connected to one HDD, another marked 'data 1', connected to the other HDD, and two pairs of command connectors, one marked 'in' and the other 'out'. I haven't yet followed the command cabling to see what the connectors connect to. There were other Xylogics SMD controllers as well. Which controller do you have in your system? Xylogics 451.

SMD disks
My Sun 3/260 came with a pair of 8-inch SMD disks in a separate cabinet. 1. Anyone have a pointer to docs that describe cabling and configuring SMD disks? My Google-fu has failed here. 2. The system came with no cables (external cables between cabinets). Are these standard cables or will they be Sun-specific? 3. The system "ran when parked" about a dozen years ago, but it was left in an open barn after that. How likely is it that the disks will work and be readable? One is a Fujitsu M2333; don't recall what they other one is. alan

SunOS 3.5 and SMD disks
Hi, I recently acquired an old Sun3 with a Fujitsu Eagle disk. This disk has SunOS 3.5 on it. Parts of the installation were missing, though. I wanted to build a new kernel with SCSI support and extracted the sys stuff from a 3.5EXPORT release tape. My machine however runs plain 3.5. I can build a new kernel, but some things won’t worked like allowing logins when a password is set. Is there anyone out there who could provide me with a tar of /usr/sys from a complete working SunOS 3.5 running on sun3? As a second question: The SunOS boot disk is a Fujitsu Eagle that often reports errors. I have a second Eagle that I might use as a backup, but I would have to reformat the second disks. How can I do that with SunOS 3.5? There is no „format“ command apparently. thanks, Dennis -- Don't suffer from insanity... Enjoy every minute of it.
