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.

This guy:

has a couple of PDP-8 boards for sale that at the moment are going _really_
cheap.

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.
