It's a Seagate Wren VII (CDC/Imprimis) 94601-12G, which formats down to just under 1 Gigabyte. It's the standard SCSI Wren VII in SunOS 4.1/4.1.1's format.dat file. The drive is about a year old (according the production date code), and is in perfect cosmetic and working order. If I recall the specs, it's got a 14.5ms average seek and a read-ahead cache (now enabled). The terminating resistors are also installed. I even have the documentation explaining all of the jumper settings... I prefer to ship sensitive electronic equipment like this via Federal Express 2nd day insured even though UPS is cheaper (I've had problems in the past with UPS); this would cost ~$35 for Fed Ex. First $1625 plus shipping takes it. Please respond via e-mail if interested. ...Marc... -- Marc Frajola, Tektronix Inc., Beaverton, OR OG Technical Computing Center Operations InterNet Address: marc@tekig3.PEN.TEK.COM UUCP: ..!tektronix.TEK.COM!tekig3.PEN.TEK.COM!marc ------------------------------ Date: Mon, 11 Feb 91 16:45:48 -0800 From: swansonc@stolaf.edu Subject: cheap Sparcstation backups To: eggert@twinsun.com (Paul Eggert) Just a quick info point on GNU tar.

That's a terrible price for a QIC-150 box! I bought one two years ago for $995 including drive, box, cables, and Mac software! Last week I bought the bare drive (Archive Viper) from ANDATACO for < $800. I picked up an old 5.25" floppy box for $75 (you can get new ones for $100), including fan and power supply. Another 30 - 40 for cables and you're set. Shop around. Even consider buying the parts and integrating it yourself: it's not that hard. -- - Steve Mitchell steve@cps.altadena.ca.us grian!steve@elroy.jpl.nasa.gov ames!elroy!grian!steve "God is licht, an in him there is nae mirkness ava." -- 1 John 1:5 ------------------------------ Date: Tue, 12 Feb 91 20:52:26 PST From: tessi.UUCP!exc!markh@tektronix.TEK.COM (Mark A. Holm) Subject: PPP on sun3's To: analogy!sun-managers-relay, Suns-at-Home@sequent.com I am currently trying to get the PPP stuff up and running between my 3/50 at home running 4.1.1 and a 3/160 running 4.0.3 at work. I used the ppp-sparc4.1 package to compile the kernals following the included instructions. Both kernals came up just fine and doing ifconfig against the ppp devices show that they are there and I can bring them up and down. Everytime that I run ppp I get the following message: ppp: ioctl(I_PUSH, ppp_async): Invalid argument What am I doing wrong? ===================================================================== Mark Holm ..tektronix!ogcvax!cvedc!exc!markh Exceptions ..tektronix!tessi!exc!markh 126 NE Grant Phone (503)648-8307 Hillsboro, Oregon 97124 Messages only until after 6:00 PM One cannot accomplish the impossible, without first attempting the absurd! ------------------------------ Date: Tue, 12 Feb 91 00:16:43 +0100 From: "Lars P. Fischer" Subject: SLC and 676M disk To: Suns-at-Home@ecn.purdue.edu >I want to upgrade. A friend recommend the SLC, and a 3rd party 676M >shoebox drive. Have any of you experience with one of these? Nice machine. The SLC is small and cute. Nice at home. For home use the *no fan* construction is a real plus. Just to bad about the noise from the disk.... You might like to experiment with the longest possible SCSI cable. The Wren-IV is a good chioce for a disk. The setup utility even knows about it in advance. >Will the serial ports support 9600 baud modems without crashing >via silo overflows? Easily. The "silo overflow" problem is long gone. It was really a software problem. "Fixed in 4.0". >How will it survive is I throw X11R4 and 1-2 >X terms on it? It might be bored to death :-). The SLC runs X11R4 easily, especially given enough RAM. There's a *big* performance advantage to installing 16 M. The SLC is close to ideal for running X at home. We have 50+ SLCs used mainly for X and Open Windows here. /Lars ------------------------------ Date: Wed, 13 Feb 91 08:56:55 EST From: rs@ai.mit.edu (Robert E. Seastrom) Subject: Sun-2/120 memory parity errors To: suns-at-home@orchestra.ecn.purdue.edu Almost 2 1/2 years ago, Alexander Dupuy (dupuy@cs.columbia.edu) sent some very informative advice to SAH about Sun-2 memory problems. Apparently, 150 ns is not *quite* good enough to keep from having memory problems sometimes. Well, I was thinking about this... I can get 1MB SIMMS for reasonably cheap (80 ns - that oughta be fast enough!), and I was thinking "why not make a board that has all 7 MB right there?" I was wondering if anyone could supply me with a circuit diagram for the 1 MB memory board or a pinout for the P2 multibus connector to use for reference when I try hacking on this.

Not only -> is it amazingly tedious, the media cost is 120 cents/MB. Wouldn't I need -> about $500 worth of floppies to do it right? Well, the way I figure it you need less than 150 floppies to back up *everything*. You only have to do that once (or twice for a backup of your backup), then you back up only changed files. The find command can be used to get a list of just those files that have been modified since the last backup. Then you can use any of various ways of getting the files onto floppy. You can buy HD floppies from places like MEI/Micro Center (800-634-3478) for only $0.79 each plus shipping and handling. This cuts down on your floppy cost. There are probably cheaper alternatives for tape drives as well, although I'm not familiar with them. -- <-:(= Anthony Stieber anthony@csd4.csd.uwm.edu uwm!uwmcsd4!anthony ------------------------------ End of Suns-at-Home Digest ******************************
