Wanted: IBM PC compatible 8 or 16 bit Arcnet cards

Sun Dec 12 15:27:03 CST 2021

 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.

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.
