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.

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.

Hi - I am looking for an IMSAI PCS 80-30 ROM image made for with the Tarbell 1011 controller and Persci 277..anyone have this? I received a system and drive but I think the ROM was replaced and since then I was told the system would no longer boot. In the meantime I am going to find a drive and controller that is compatible. Or, ug, have to try to edit the ROM I have (version 1.1) to operate with this hardware. I would not having a copy of ROM 1.0 at least to start from scratch with. Thanks Bill Degnan

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?

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.

Printer Transparencies?

by healyzh＠avanthar.com

Here is a strange question. Does anyone happen to know how long unused Laser Printer and Ink Jet transparencies last? Do they go bad, or break down? I have a stack of them, still in the boxes, a lot are unopened. I scavenged them about 10 years ago, when people were getting rid of them. I wanted them for a Photography Project, that I?ve never had time to try. At this point, I?d like to know if I?m wasting space storing them. Zane

Can't Select a Custom Device in Eagle

by robert.jarratt＠ntlworld.com

Never mind, I just realised there was a little "+" sign well away from the symbol that allowed me to select it. It looks like the symbol is somehow much bigger that how I have drawn it. I should be able to work it out now.

I decided I needed to make a custom device in Eagle for the transformer. I have done this and it seems to be fine, except that when I put the symbol on a schematic, after I have confirmed its position, I can't select it, so I can't move it or anything.

Mystery 1970 core board

by jules.richardson99＠gmail.com

Hopefully collective wisdom can help on this one - does anyone have a clue what system this core board was from: http://www.classiccmp.org/acornia/tmp/coresmall.jpg The curved edge connectors (presumably to make board insertion easier) are quite distinctive, plus the way the power's fed in via an edge connector on the "far" side of the board. What's interesting to me is the core ring size; the TTL ICs on the board have 1970 date codes, but I didn't think that the rings got quite that small until right at the end of core's era, more toward the end of the decade. It seems to be 8 blocks of 64x64, i.e. 4KB. p/n on the main board of 2001000755, and just hidden from view under the core daughterboard is a logo that says "LEC", which I suppose might be meaningful. There's a bigger (2181x1863) image as "coreboard.jpg" in the same dir if more detail helps (I doubt it), but it's 2.4MB so maybe save Jay's bandwidth by only looking at that one if you absolutely have to :-) thanks, Jules

For those with 6809 experience

by brain＠jbrain.com

Looking at the datasheet for the 6809 (specifically, the 6809E that needs incoming quadrature clock), I read that !HALT can be asserted 200nS (for 1MHz part) before falling Q and the CPU will finish the existing instruction and then go into a HALT state as long as the HALT line is low during the falling edge of Q. That's the store from the datasheet, but when I am testing it, I see that, even if I pull HALT low at the very beginning of the last cycle of an instruction, the 6809 will not acknowledge the HALT until executing the next instruction. My logic is watching for IO address $ff61.? When found, it drops Q so, to start the HALT condition, I need only: lda $ff61 Not that the trigger is being performed by the code, so the current instruction (the lda) should complete and then the CPU should go into HiZ.? What I see is: lda $ff61 lda $ff60 <- the next instruction executed, and THEN the CPU goes into HiZ. I can deal with this (Yes, I should just look at BS=BA=1, which tell when to safely use the bus, but I don't have access to those signals for this project), but I thought I'd see if this was known by all, or if there is something I am missing.

SWTPC 6800, FLEX and Percom Floppy

by deramp5113＠yahoo.com

Now that I have my SWTPC 6800 loading and saving programs with paper tape, cassette, and floppy disk (using the Percom LFD-400 controller and their MiniDOS and MPX ?operating systems?), the next logical step is getting FLEX up and running. Unfortunately, I only have the Percom floppy controller and I don?t know if FLEX compatible disk drivers and boot code were ever written for it. Before I go create Percom support for FLEX from scratch, does anyone have any leads? Mike

The floppy eject button was then closest to the operator and any disk inserted would be visible from the "rear" of the floppy. Not nearly as weird as the Altos ACS8000, for example, that mounted the floppy drives upside-down and horizontally, such that the eject button was topmost. Those disks do have content labels placed on what we'd consider the "backside" of the floppy for obvious reasons. Did any 5.25" floppy-equipped systems do this? --Chuck

What is this System 360 peripheral/maintenance console?

by steven＠malikoff.com

I was watching this video on highway construction in the 1960's (as you do) and noticed what appears to be a System 360 console, that I couldn't place. Presumably it's some peripheral or CE maintenance panel. I didn't find it in the Physical Planning Guide (not that that's comprehensive) nor from perusing google images. I'm a little curious as to what it is. It's at 23:13 in https://youtu.be/apWSa6QlrTg?t=1393 Thanks Steve.
