Not that I know of. In principle iSCSI can handle tape, but I don?t know if it?s been done at all, never mind in Linux. paul

EPROM image for CMD CDU-710/M or 710/TM?

by derschjo＠gmail.com

Hey all -- I'm looking for an image of the EPROM on the CMD CDU-710/M or /TM UNIBUS SCSI adapters. The 720s have been archived, but only the /T (tape only) variants are imaged for the 710... Anyone out there have one of these boards and be willing to dump the ROMs? Thanks in advance, Josh

I think iSCSI target support is now a standard Linux iSCSI feature. If not standard, at least reasonably mainstream. I haven?t tried it, but I see plenty of references to it on the Linux iSCSI mailing list. paul

Identifying a magnetic recording head

by kylevowen＠gmail.com

Any idea what this came out of? I was thinking some fixed head hard drive, but I'm not sure. It looks new. The coil resistance is about 4 ohms and >from measuring it, seems to be center-tapped. http://imgur.com/a/mHZS4 Thanks, Kyle

Wanted: PDP-11 Unibus Ethernet interface from Xerox, c. 1981

by jnc＠mercury.lcs.mit.edu

> From: Al Kossow > I have several of them. Wow. I'm totally stunned! Do you have any 3-Mbit transceivers to go with them? If you (or anyone) need, I can provide old code for an IP/PUP router to connect a 3-Mbit Ethernet to a 10-Mbit (if you want to put, say, an Alto on the Internet - not sure if they ever did a 10-Mbit card for the Altos). It would need either a UNIBUS 11, or a QBUS 11 and a QBUS->UNIBUS converter. (The DEC one is UNIBUS->QBUS, so would not help us.) > Anyone still have Unibus Chaosnet cards? Another rara avis! (I don't remember if they ever made any QBUS ones.) Noel

Wanted: PDP-11 Unibus Ethernet interface from Xerox, c. 1981

by jnc＠mercury.lcs.mit.edu

> From: Rich Alderson > SAIL .. did not use the MEIS (Massbus-Ethernet Interface Subsystem) for > Ethernet connectivity, but rather a Unibus card from Xerox (apparently > used to hook -11s to D-machines) which went into the front end 11/40 on > the KL-10. If this is the card I'm thinking of (we got two as part of the Xerox donation of Altos, a Dover, etc to MIT, BITD), it's to a 3-MBit Experimental Ethernet, not to a 10-MBit Ethernet, and so won't be much use unless you have something else with a 3-MBit Ethernet (and of course you'd also need 3-MBit transceivers, etc, etc). And of courset those cards were made in very, very limited numbers; if any survive to this day, I will be absolutely astonished. If you have a pointer to the PDP-11 code, I can take a look at it and confirm if it's a 3-MBit card. (The hardware packet header format is completely different from that for a 10-MBit.) Noel

Old ALR, Unisys, Burroughs equip

by sales＠elecplus.com

I just got off the phone with a gent who has a 7,000 sq foot warehouse in NJ. He has old ALR, Unisys, and Burroughs servers, terminals, keyboards, and storage (9GB drives). If you are interested, send him an email at ehogan at unimetrix.com. His name is Ed Hogan. Cindy Croxton

Wanted: PDP-11 Unibus Ethernet interface from Xerox, c. 1981

by jnc＠mercury.lcs.mit.edu

> From: Al Kossow > There was a 10mb card Xerox made [later] > There never was a 10mb card. ?? > I would be interested in the code for an 11. Alas, the CGW code online at MIT: http://web.mit.edu/afs/net/project/cgw/ doesn't contain the PDP-11 version (or the Experimental Ethernet drivers, etc). I have the hardcopy of the PDP-11 version, and somewhere on the MIT V6+ Unix tapes that I'm currently trying to excavate, there will be machine-readable, but I've been trying to get to those for some months now... too much else to do! :-( If you get to a point where you need it, let me know, and if I don't already have it done, I'll move it up the priority list.
