Well to satisfy my craving for a 9-track tape drive I have decided to start looking for something I can manage. Yes, I would love a 3240 or that massive IBM 5360 (system/36?) on the Vintage computer marketplace but I have to get serious and remember that that kind of gear weighs too much for a teen like me to ship. Anyways, yeah I am looking for an IBM 9348 scsi tape drive. I was looking into using it in a little IBM 360 emulator that runs on Ubuntu but mainly it's for bragging rights (Chicks dig guys with big drives). Now while it is samller it's still hjeavy (if you alrready have one than you understand me here) so if you want to part with yours PLEASE promise me that it works before I shell out. It would be nice to get one locally too. Identification photos can be found on the link below. http://ripsaw.cac.psu.edu/~mloewen/Oldtech/IBM9348.html Thanks. _________________________________________________________________ Invite your mail contacts to join your friends list with Windows Live Spaces.

Catweasel NorthStar / Catweasel Heath?

by w6nct＠arrl.net

Hi Andrew, I can probably help you with this, if you don't already have a line of volunteers. I'm interested in archiving some "stuff" off my (and my Mom's) old H-89 diskettes before I start disposing of the hardware and excess media. Although most of my personal stuff was saved on soft-sectored 5.25" and 8" media, a small amount of my information (and all of my Mom's) was on the hard-sectored media. We can work out any details off-list. Please contact me directly if interested. <<< vern >>> ----- Original Message ----- From: <cctalk-request at classiccmp.org> To: <cctalk at classiccmp.org> Sent: Sunday, September 30, 2007 10:05 AM Subject: cctalk Digest, Vol 49, Issue 74 ---------------------------------------------------------------------- Message: 28 Date: Sat, 29 Sep 2007 13:39:27 -0400 From: "Andrew Lynch" <> Subject: Catweasel NorthStar / Catweasel Heath?

The Heath H89 computer using H-17 disk controller uses the same media as the NorthStar (10 sector 5.25" hard sector floppy disks) and in some superficial ways are similar to the NorthStar SSSD disk so this seems like a logical next choice. I would like to extend the concept of CWNS to include Heath hard sector disks (i.e. Catweasel Heath, CWH) My theory is the main difference between CWNS and CWH will be the bit stream decoding logic. The H-17 disk format is entirely different than the NorthStar MDS-A series disks. However, the disk format is documented here: http://davidwallace2000.home.comcast.net/h8/project8080_archive/design_h17.h tml#format A major problem with this plan is I do not have an H89 or any Heath formatted disks. I am seeking a partner to collaborate on this project. If someone would send me some Heath formatted hard sector disks, I will start the investigating whether a Catweasel Heath program is feasible. Please do not send irreplaceable originals or critical data disks. I need working disks you can afford to either lose or be damaged as a result of testing the software. Please contact me offline or reply to this message if you are willing to help out. Thanks! Andrew Lynch End of cctalk Digest, Vol 49, Issue 74 **************************************

pdp 11 boot roms

by jwest＠classiccmp.org

My semi-yearly reminder.... Would anyone have the DEC boot rom for the M9312 that boots off TMSCP TK50 & TU81 (MU)? Please check your M9312 boards and your PDP-11/44 boot roms for rom "E39A9" or part number "23-E39A9". If you have it, I (and a few others) would love if I could borrow it to make an image. Best regards, Jay West

Anyone collect Dec/Compaq Alphaservers or VAXen?

by ddsnyder＠zoominternet.net

To all, I have monitored the postings and know of a few collectors of VAXen, all types it seems. The PDP family is popular too. What about Alphaservers? some are by classic definition at least 10 years old such as the 1000/1000A and 1200 series. Alphastations definitely qualify like the 200/250/255/500 series. I collect most of the Alpha family as I use them frequently. OpenVMS and Digital Unix is the OS of choice. I have in my collection: 1 Alphastation 200/166 - 192M 1 Alphastation 250/266 - 256M 1 Alphaserver 400/233 - 256M 1 Alphaserver 800/500 - 2G 1 Alphaserver 1000/266 - 768M 1 Alphaserver 1000A/333 - 1G 1 Alphaserver 1200/w dual 533 CPUs - 2G 1 Alphaserver DS20/w Dual 500 CPUs - 4G 1 Alpha PWS 600au - 2G 2 Alpha XP1000/667 - 2G 1 Alpha XL366 - 256M 2 DEC3000 300X - 256M 2 Alphastation 500/400 and 333 - 512M I have VAXen as well, fully loaded 2 MicroVAX 3800 w 64M and fully loaded with QBUS options The VAXen are not used as often, but I have one client left that still has these machines in use. I remember the PDP family as I have used them in the past, but I do not have any desire to re-live that part of my past. Enough for now, let me and/or the group what you have. Maybe we can form some sort of list for contact and advice or maybe part swapping. Dan

Motorola S-record converter source for new project

by w6nct＠arrl.net

Hi Robert; I am not familiar with the particular program you refer to; but I used to have a couple similar programs to convert S-records. If you like, I can look around and see if I can find one or more for you; or maybe even some documentation. As I recall, the last time I messed with it, I just wrote a quick TCL script to convert the few record-types I needed. Many times, that is easier than writing a comprehensive converter. Do you know which record formats you need converted? <<< vern >>> ----- Original Message ----- From: <cctalk-request at classiccmp.org> To: <cctalk at classiccmp.org> Sent: Thursday, September 27, 2007 10:00 AM Subject: cctalk Digest, Vol 49, Issue 68 ------------------------------ Message: 8 Date: Wed, 26 Sep 2007 15:40:40 +0200 From: Robert Mounier <robertlp.mounier at 9online.fr> Subject: Motorola S-record converter source for new project To: cctalk at classiccmp.org Message-ID: <006901c80042$d6a072a0$45474c56 at BARCO> Content-Type: text/plain; charset=iso-8859-1 Hello, On internet I found a chat where you write about Lilbug.asm. Could you please help me to findinformation about it. Many years ago I used to work with 6801L1 coming with LILbug monitor. Today I still have few pieces, but I no longer have any documentation about the monitor. Could you help me to find an user manual of the LILbug or more simply the list and syntax for the commands and addresses of the routines (like conversion Hexa-Ascii and so.). In advance many thanks for your answer. ------------------------------

Who was putting together the TSX+ archive?

by shoppa_classiccmp＠trailing-edge.com

In the past couple years somebody here was putting together an archive of TSX+ stuff. I have about 15 pounds worth of paper 6.31 manuals, including some release notes up to I think TSX+ 6.50, and some other release notes going back from 6.31 too. Is this already in the archive, or would it be useful? There was some mention of it being in bitsavers but I don't see an S&H or sandh directory there. Tim.

OT: nifty equipment sighting

by mcguire＠neurotica.com

In Stargate Atlantis, season 2 episode 19, I spotted the console of an Etec Autoscan scanning electron microscope, identical to mine. It appears on what I think is the bridge of the warship that McKay is working to resurrect, a moment after "more fissures open" in the volcano. Neat! -Dave -- Dave McGuire Port Charlotte, FL Farewell Ophelia, 9/22/1991 - 7/25/2007

Hi This doesn't look like oxide, it looks like tungsten crystals. these form as the filament evaporates and recondenses on the filament. This is part of why they fail. There are two factors. One is that they tend to thin over time by evaporation. The other is that they tend to get more brittle over time. It is rare to see one fail because of loss of vacuum but when it does, the filament turns to a whitish yellow powder. Most lights do not have a high vacuum. If they did, the glass would cover with evaporated tungsten quickly and bock the light. You might notice that only the tops of the bulb get darkened. This is because of simple convection of the gas in the bulb. Dwight _________________________________________________________________ News, entertainment and everything you care about at Live.com.

WTB/Trade: DECstation 5000/133 memory

by sethm＠loomcom.com

Hey everyone, I'm looking for 8 or 16 sticks of memory for a DECstation 5000/133. These are 4MB 80-pin 70ns ECC SIMMs. I don't remember the DEC part number for these, alas. If you're interested in a trade, I have a metric buttload (that's a technical term) of MS02-AA DECstation 5000/200 memory I'd be willing to trade. Please let me know if you have any! Regards, -Seth Morabito
