Recommendations for AIM-65 power supply?

by derschjo＠mail.msu.edu

Title basically says it all -- anyone have any recommendations for a decent power supply for an AIM-65? I have it running right now on just 5V, but I need something that puts out 24V so I can run the little printer, too :). It'd be nice nice to something small enough to fit inside the enclosure this thing came in but I'm not that picky. My searches on the 'net reveal a lot of choices, so I'm looking for advice on what to look out for. For those playing along at home, the AIM-65 wants 5V at ~2A, and 24V at ~2.5A. Thanks! Josh

Overland Data 9-track drive

by IanK＠vulcan.com

In one of my fortunately few poor deals on eBay, I bought an Overland Data 9-track drive, identified on its tag as an OD 3601 GCR. It's an interesting unit, a bit bigger than a briefcase and standing "on end" with the drive reels facing out. It has both a Pertec-style interface and a PC serial interface. It looks pretty cool. There are only two problems. One is a broken door hinge - not a big deal. The other is that the drive does not respond to any control input - a big deal. After asking about, someone told me that the flashing LEDs on its face mean that its main electronics have failed. I'm guessing that one or more of the many EPROMs in it have lost their minds. It's a really nice looking unit, but it doesn't work. So I have an offer or two I'd like to make. If you perhaps have one of these drives, and it has a bad mechanism but good electronics, I'd be glad to give this to you for the actual cost of shipping. On the other hand, if you have those good electronics but don't want/need the drive, I'd be glad to talk about obtaining the innards from you for a nominal cost (shipping and some beer money, perhaps). Anyone interested? Thanks -- Ian PS: this is a piece in my personal collection. I'm just using this email account because this is where I read the list.

Copying simh images onto real disks

by toby＠coreware.co.uk

I've been trying to get BSD 2.11 running on my uPDP-11/73. Rather than going the vtserver route, I thought I'd try to speed things along by making a disk image under simh and then copying it onto a SCSI disk for use on the PDP-11. I successfully built a 300MB disk image under simh from the BSD 2.11 tape and then copied this onto the SCSI disk with: dd if=bsd211.dsk of=/dev/sda However, when I put the disk onto the -11 and try to boot DU0, it just hangs. Anyone know where I am going wrong? Many thanks, Toby -- This message has been scanned for viruses and dangerous content by MailScanner, and is believed to be clean.

Apple Laserwriter 16/600PS, parts/repair, free

by mcguire＠neurotica.com

I have an Apple Laserwriter 16/600PS available for free, just pay shipping. (continental US only, please) It functions, but it jams 30-50% of the time. It is just wearing out. I've babied it for many years and it is in pretty good shape otherwise. If you want to (probably) replace the pickup rollers and give it a good cleaning, you'll have an absolutely wonderful 16PPM, 600DPI, TCP/IP-capable Ethernet-connected PostScript laser printer that works well in the Mac, Windows, and UNIX/Linux worlds. It comes with a paper tray, but no toner cartridge. (same cartridge as HPLJ 4/4M/etc, Canon EX engine if memory serves) Continental US shipping should be $40 or so. PayPal me that and it's yours. -Dave -- Dave McGuire Port Charlotte, FL

DEC Equipment - Tucson, AZ

by technobug＠comcast.net

I was wandering around my local scrapper and found four PDP11/23+ chassis (without cards) and three RL02 on a pallet in purgatory (prior to triage). If there is any interest, drop him a line @ "<keith at swliquidators.com >. He promised to hold them for a week or so prior to making a decision to scrap. CRC

More Info RE: Emulex SCSI Controllers available...

by lbickley＠bickleywest.com

I've received a number of responses from folks - and a few questions. Here's answers to the most common questions: 1) Is there a warranty? Yes the boards are guaranteed by the dealer to not be DOA. I just re-checked - and he's agreeable to a 15 day warranty. My guess is that if you went a few more days, he'd cover it - but he would like whoever gets the boards to check them out right away. ALL boards will be pre-tested by the dealer on a QBUS system using RT before shipping. All will have the latest EPROMS. 2) Is it standard QBUS (i.e., not "S") Yes. 3) Is the SCSI port standard 50-pin? Yes. Lyle ---------- Forwarded Message ---------- Subject: Emulex SCSI Controllers available... Date: Thursday 26 February 2009 From: Lyle Bickley <lbickley at bickleywest.com> To: "General Discussion: On-Topic and Off-Topic Posts" <cctalk at classiccmp.org> I was chatting with a DEC broker recently regarding SCSI controllers for DEC gear - when he mentioned that he had a quantity of Emulex UC07's available. UC07's are QBUS cards which have a single SCSI port and support either MSCP or TMSCP (in RT land, that would be either DU or MU devices). The manual states that the UC07 is compatible with RT, RSX, RSTS/E and Ultrix versions which support MSCP or TMSCP. The dealers initial price was high (as expected). However, he then added - "I'd be willing to do better for hobbyists - as long as they commit that the boards will only be used for hobby purposes - and not for commercial use". So here's the "deal": $235 per UC07 plus shipping from Mountain View, CA (FedEx Ground). I've paid MUCH more for SCSI interfaces for my DEC QBUS and UNIBUS systems - so IMHO, this is a great deal. The broker said he did not want to deal "individually with a bunch of hobbyists" - so he asked if I would be willing to consolodate a single order of UC07's to him. I reluctantly said "yes", as this is not my business and I'm not interested in making money on this deal - only covering costs. To get a sense of interest, please reply to me privately if you'd like one or more if these "critters". The manual for the UC07 is available on bitsavers.

Archiving 8" RT-11 floppies to CD-ROM?

by dbetz＠xlisper.com

I have a friend who has a number (10-20) of 8" RT-11 floppies he wants to archive to CD-ROM or some other modern media. Is there anyone in the Boston area (he lives in Medway) who could help with this? I believe these are RX01 media since I think they were created on a PDT-11/150 that I gave away to someone a few years ago. Can anyone here help? What would the fee be for such a service? Thanks!

by legalize＠xmission.com

I'll be visiting Seattle next week for the Microsoft MVP Summit. The Summit wraps up on Wednesday around 5pm in downtown Seattle.

Last time I got to check out bear's collection (r.stricklin) and I'd love to see anyone's collection that's willing to share :-) Email me off-list and let's trade contact info and I'll give you a hollar! -- Richard -- "The Direct3D Graphics Pipeline" -- DirectX 9 draft available for download <http://www.xmission.com/~legalize/book/download/index.html> Legalize Adulthood! <http://blogs.xmission.com/legalize/>

truck trip, space available

by mcguire＠neurotica.com

Hey folks. It looks like I'll be making a road trip from Port Charlotte, FL (just south of Tampa, Gulf coast) all the way up to Boston, and then back down, sometime next week. I'll be in a 24' truck with a lift gate. The southbound trip will be full, but the northbound trip will be at least half empty, so I may be able to move big and/or heavy stuff along that route. The requirements are that it be not too far off of Route 95, and that any stops not take too much time. I will need a few bucks for this. Be aware that the scheduling and other details of this trip are not yet set in stone. Any thoughts? I'll need to hear back soon. Please CC me on any replies, or email directly, as I'm only on cctech. -Dave -- Dave McGuire Port Charlotte, FL

43 "classic" articles about our hobby

by evan＠snarc.net

>From the better-late-than-never department .... Tonight I posted 43 articles from the former Computer Collector Newsletter / Technology Rewind. Many of you will recall that I published this a a weekly e-newsletter from Jan. 2004 to March 2006, with the help of Sellam Ismail, Christine Finn, Erik Klein, Bill Loguidice, Michael Nadeau, and many others. The newsletter ran for 2 years and 3 months. Now it's been 2 years and 11 months since the end. So, I finally got "a round tuit". Read them at http://www.snarc.net/tr/newsletter.htm. - Evan
