Content of www.blacksheepnetworks.com

by rumi_ml＠rtfm.hu

Hello, This site used to have a lot of very useful and rare information on Tru64 troubleshooting and Google still has the links to the articles but the content itself is inaccessible: http://www.blacksheepnetworks.com/security/resources/tru64/ Has anyone by any chance archived the content of this site while it was still alive? archive.org did not, unfortunately. Thank you! Kind regards, Sab

Wanted: IBM PC compatible 8 or 16 bit Arcnet cards

by mbbrutman＠brutman.com

I'm using debug logs to try to debug flow control issues when using mTCP and a packet driver that presents itself as Ethernet but actually uses ARCNET. I've gotten to the point where I just want to have an Arcnet in the house. Especially since I might just modify mTCP to work with Arcnet packet drivers and cards directly. Before I get too serious with eBay, does anybody want to rehome some Arcnet hardware? -Mike

ISO: DEC PDP-8 Data Multiplexer (DM01, etc.)

by derschjo＠gmail.com

Hey all -- Got the TC01 working the other night, after a couple weeks of debugging (*). I'd like to be able to have both it and the RF08 that I'm working on connected to the 8/I and running at the same time, so I'm looking for a DM01 Data Multiplexer. If anyone has any leads, do let me know. Thanks as always, - Josh (*) Total TC01 fault count (so far): - Bad transistor in TU55 motor brake control (W040) - Bad jumper solder joints in TU55 (W990) - Timing of UTS and U+M one-shots (R303) way out of adjustment (U+M one-shot was at 2 seconds or so...) - Bad tape data relay (G851) - Bad IOT decoder transistor (W103) - Missing Diode (W113) and weak diode in Write enable selection logic - Timing of write clock way, way out of adjustment (90Khz vs. 125Khz expected.) - 24 dead maintenance panel bulbs - 2 dead TU55 bulbs (yet to be replaced)

NI PCI-GPIB+ Analyzer boards on ebay

by guykd＠optusnet.com.au

About the software: I bought a couple of that seller's cards; one each of 284088568161 & 284088570014. Asked him about the software. Here's his reply. ======== Regarding your question about the Analyzer software, if I recall correctly it comes bundled in the "NI-488.2" software package. I believe the version in my screenshot in the eBay listing was v17.6 for Win7 SP1 x86, but it should still be fully supported in the newest v21.0 package for x86 or x64 systems. https://www.ni.com/en-us/support/downloads/drivers/download.ni-488-2.html LabVIEW version compatibility matrix: https://www.ni.com/en-us/support/documentation/compatibility/17/ni-488-2-an… ======== All new to me. Now to hunt manuals for the cards.

RC11 controller (Was: Reproduction DEC 144-lamp indicator panels)

by jnc＠mercury.lcs.mit.edu

> From: Steven Malikoff > Was there ever an indicator panel for the RC11? .. I have a set of RC11 > modules .. No backplane though. I've not found any docs for these, I suppose > they're probably on bitsavers and have overlooked them. Looking at the manual and engineering drawings (at BitSavers, as you guessed), no lights. I've added links to those to the CHWiki RC11 page: https://gunkies.org/wiki/RC11_disk_controller The engineering drawings have the wirelist for the backplane, so it would be possible to wire a new one. (I'm in the process of doing that for my KE11-A.) Not sure it would be much use without an RS64 drive, though. Noel

Reproduction DEC 144-lamp indicator panels

by jnc＠mercury.lcs.mit.edu

> From: Tony Duell > I have _two_. But alas nothing to connect them to. Well, there are still a good flock of machines with IBM channels around, but _you_ don't have one (I can't blame you :-). I wonder if any of the people with IBM channel machines have any need to connect to an -11? Speaking of extant dinosaurs, I wonder if any RF11's still exist? Noel

Siemens T100 Terminal with Paper Tape - Available

by mmcgraw74＠gmail.com

I have this terminal in my garage - sitting on its custom stand. I purchased it years ago, but don't have a use for it. Here is my photo of it: https://drive.google.com/file/d/1SV4-Xx7XLHIoA898ZPRC74wZv2e8YsVK/view?usp=… I'm near Houston Texas. It is too big and heavy to ship. Monty McGraw
