My web space is near its limit. Any suggestions? The rack that holds the TU81+ tape drive has underneath the space for an RA8x drive. I had it that way, but one year ago I removed the RA82 and installed two of these SA72's. It is intended to be hooked up to the VAX-11/750, but the VAX has PSU "issues". I am pretty sure I have two more SA72 without drives, but contains the PSU is in it IIRC. However, even without any drives installed these things are good if you want to hurt your back :-/ So, shipping one is not an option. I even have a plate that is mounted in the rack ... If you wonder how the SA72 is mounted in a rack, given that its width is just half the width of the rack, well it just "hangs" on one side! The SA72 at the right side hangs on a plate mounted in the rack at the right side, and the SA72 at the left ... on a plate at the left side. Even such a plate is good for a few kilos on the scales! - Henk

Idol You may very well be right Johnny. I was just dumping my grey memory cells :-) I did not check the HW. Isn't the SA72 a small slim long metal box with a power supply in the middle and room for two RA[79]x drive at both ends? At the front side at the top is a connector for the small front panel. The width of the front is 0.5 of 19" so that two of these fit next to each other in a 19" rack. If that's way off, I'd have to check what I actually have ... - Henk.

Preferred image format for HP single-sided 3.5" floppies?

by aek＠bitsavers.org

I have a small stack of single-sided disks that I need to image, and didn't realize that they are 18 sector with 0-16 256 bytes and 17 128 bytes, so Imagedisk won't work. What is the preferred container format? Looks like the Australian museum uses .td0

OT: Google AdWords and Yahoo/Bing adCenter

by arkaxow＠gmail.com

I just started using Google Adwords and I?m trying to figure out how they charge. I just finished the free first time allotment of $75, now I have to add more money. Does anyone have any experience with this ? Also I?m looking into the Yahoo/Bing adcenter.microsoft.com. They don?t seem to offer a free first time allotment. Does anyone know of any way to get a free startup allotment ? Jeff Brace

Free: Hughes Personal Earth Station

by devonstopps＠gmail.com

Not sure if anyone has any interest in a Hughes Personal Earth Station circa 1989 - was in use up until early 2011. I also have 3x serial interface breakout boxes with 4 ports each for it. Looks similar to: http://www.mebstore.com/items/item_display.aspx?iid=61910 http://www.thrustssc.com/thrustssc/Equipment/Hughes/PES_and_CODECs.JPG Free for pickup, item is in Toronto, ON, otherwise will be scrapped next week.

need interface to CDC Keystone (92185) tape drive

by elson＠pico-systems.com

Hello, I was referred by a member, Peter Wallace. We are trying to recover some programs from 9-track backup tapes. I have a working 92185 drive, and had salvaged a SCSI - Pertec formatted interface converter off the back of a Cipher 990 drive at work. The Cipher 990 was total crap, hardly ever worked. The SCSI converter actually worked for a while, I was able to read a few blocks of tape (without a proper program to handle the format, I just did stuff like sudo cat /dev/st0 on a linux system, and got info that looked like the first couple records off a tape. Then, the converter died, it stopped passing its internal self test. But, I had proved the 92185 drive is OK. So, now I'm looking for a way to read these tapes. The best solution would be an off-the-shelf SCSI - Pertec converter, which were made some years ago, but will be hard to find on eBay or such. Another way is to find the SCSI interface board for the 92185, but I've never found one to buy. Another way is to get my Vaxstation running again, the hard drive blew, so it would take some effort to get that back up. I have a Dilog DQ15 controller for it, and if that won't work, I probably have another tape controller, too. Another problem with the VAX is I'd have pull all the data off the tape over a serial interface, it was last running VMS 4.7 without TCP networking. Anybody got any goodies in the basement, any good ideas of how to interface it, etc.? One other choice is to build my own FPGA Pertec interface. The formatted Pertec interface is about as simple as you could imagine, but I'd need to add an SRAM buffer to the FPGA to handle up to 64K byte blocks. Jon

AFAICR, you can not > simply install the RA70 in the SA72. Hum. Correct me if I'm wrong, but isn't the SA72 the box that holds up to 4 RA7x drives? Same physical size as one RA90? If so, then no, it don't hold 4 RA9x drives. Also, the RA70 works just fine in it, as do all RA7x drives. RA70 is somewhat unique, though, in that it was designed to also be usable without any front panel at all. So there are dip switches on it that can be used to set the unit number.

Unidentified Emulex card from 1991

by dennis_mailing_lists＠conus.info

Hi. I got unidentified Emulex card from, probably from 1991. It is 16-bit ISA, it has two connectors male DB-25 and male DE-15F (like on VGA cards, but male). It is probably multi-port card, but I'm not sure. Here detailed photos: Label: http://yurichev.com/non-wiki-files/unknown-emulex/emulex1.jpg Component side: http://yurichev.com/non-wiki-files/unknown-emulex/emulex2.jpg Back side: http://yurichev.com/non-wiki-files/unknown-emulex/emulex3.jpg Connectors: http://yurichev.com/non-wiki-files/unknown-emulex/emulex4.jpg Does anybody here know what this is and whether it's possible to get manuals? Programming manuals?

identify a weird lug

by dgriffi＠cs.csubak.edu

I'm trying to identify a battery clip that seems to actually be a lug of some kind. Would someone please take a look at http://661.org/tmp/kk2048.jpg and tell me what it might be? -- David Griffith dgriffi at cs.csubak.edu A: Because it fouls the order in which people normally read text.
