I have paper copies of a few manuals I have no use for. Most of these are single-sided photocopies made by others and sent to me for scanning years ago. These are not originals. Almost all of them appear to be available on bitsavers, but if you have a penchant for paper, this might be your chance. Available by post (for whatever it costs to send them plus the paypal fee) or by arrangement in Reading, UK. MicroVAX Troubleshooting and Diagnostics. EK-O19AE-SG-005 MicroVAX Dual-Host Systems. EK-338AC-DH-003 VAX-11/780 Unibus Adaptor Technical Description. EK-DW780-TD.001 VAX-11/730 Diagnostic System User's Guide. EK-DS780-UG.002 VAX-11/780 Installation Manual. EK-SI780-IN-002 Translation Buffer Cache and SBI Control Technical Description. EK-MM780-TD.001 VAX-11/780 Hardware User's Guide. EK-11780-UG-001 VAX-11/780 Console Interface Board Technical Description. EK-KC780-TD.001 FB780 Floating-Point Accelerator. EK-FP780-TD.001 MS780 Memory System Technical Description. EK-MS780-TD.001 * KA780 Centraler Processor Technical Description. EK-KA780-TD.001 * KA655 CPU System Maintenance. EK-306AA-MG.001 The last two (marked *) do not currently appear to be on bitsavers. They do appear in my index of local files so I'll make them available to Al sometime soon. Send emails off-list please. Antonio -- Antonio Carlini antonio at acarlini.com

1st Annual Kennett Classic October 16-18 2020 - Mark your Calendars

by billdegnan＠gmail.com

Hey all - We have had soft-launched it on our website calendar a few months ago but I wanted to confirm that yes on October 16 - 18 2020 the first annual "Kennett Classic" weekend is scheduled and a GO; venue booked and implementation is under way. The centerpiece of the weekend will be a contest between teams of vintage computer hobbyists competing for the Kennett Classic Cup, an award to the team with the best network of vintage hardware based on up-time and connectivity. There will be a substantial prize awarded to the winning team. We're really excited to share the details of this event, but stand by for now. In addition to the on-site teams, we will open the contest to any qualifying team worldwide. This is a first-of-its-kind world-wide vintage computing networking event! We're working on the registration pages now, and once they're live we'll share all of the details. Think of the Kennett Classic Cup as a car rally for vintage computers. We have many other activities planned for that weekend, stay tuned. Interested? We look forward to making this a huge success.

ISO National Instruments MPW DSP tools

by aek＠bitsavers.org

One shot in the dark if anyone has the DSP development or interface toolkit for NI's TMS320C30 Nubus cards. I have a bunch of boards but never found any software to use with them. This is probably LabView 2 or 3 timeframe. I see NI, who is normally pretty good with keeping manuals around doesn't even have them online any more for boards like the DSP2300

Any fun SunWindows/SunView stuff?

by cmhanson＠eschatologist.net

I have my Sun-4/110C set up and running SunOS 4.1.4. Were there any fun SunView applications or hacks back in the day? Other than the demos, the only stuff I currently have is emacstool (built as part of emacs 18.59) and the PLATO client (which I haven?t actually built yet). I know I can read through the comp.sources.unix archives but I figure maybe some folks might remember things to look for. -- Chris

Is this IBM keyboard compatible with the IBM 3279?

by mattislind＠gmail.com

The connector is the correct one. It has four jumpers that could be used for setting one of the keyboard types using the KB ident lines. https://i.imgur.com/PhfvKaV.jpg https://i.imgur.com/VPT38cK.jpg https://i.imgur.com/nN1gtFu.jpg Which terminal was it used for originally? /Mattis

RD53 failure modes

by ce.murillosanchez＠gmail.com

Hello folks; I've recently had some free time and decided to look at some hardware failures in my small collection.? I fixed a couple of analog boards in the compact Mac department, and a failed scsi disk in one of them prompted me to test the small stash of such drives that I have.? Turns out, about half of those marked as "working" in 2015 have failed now in many different ways.? Oh well... sucks, but it was to be expected... I decided to image some of the still working ones, both in the stash and in working machines.?? The one in the vaxstation 2000 (a 1GB scsi with 5.5-2) turned out to have file system corruption (probably from? AC power failures), which has taken a while to fix.? And then, I remembered that said system originally came with an RD53 that has sat elsewhere for 25 years.? It passed a read test in 2005.? So I tried to see if I could read it and maybe image it now, but no go. The disk spins up, initiates a seek (the arm is not stuck in a gooey stop pad; I've read that this is a common failure mechanism for Micropolis 1325's; I opened it and saw the arm move) but then the arm returns violently (clacking) to the rest position; it does this a number of times (two to four, usually) and then it spins down. Applied voltages and currents remain ok as this happens. I've seen plenty of internet content about solving the stuck arm problem, but not this. Advice, please? Carlos.
