I'll be following your progress with interest, I just installed Coax into the walls of my computer playhouse so I can ARCNet with my S-100 system. I have an ARCNet packet sniffer that can be loaned out if you would find it helpful.

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)

Tap handles and DEC boards?? Odd mix.
I took a risk and bid.? I have an -8/e and -8/m to fix.
Thanks!

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?

Greetings,
I had quite a few arcnet cards laying around a while back, I had picked up
a ton of them from the back storage of a datacenter that was clearing out
surplus equipment. I am uncertain of how many I still have in storage. How
many do you need?
If you are able to wait a couple days, I can check how many I have
remaining in storage, and I can ship them to you once found.

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.

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.

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?
