Thick or Thin?

Bonus points for 10-Base-5.

Super bonus points (and presumably therapy) for 10-broad-36.

OK, I haven't taken it back out of the box, but anyone still have 8
bit ISA Arcnet with thin coax?

I HATE soldering the terminating resistors... :frowning:

No, but I remember controlling stacks of Mulitech modems with an
Arcnet RJ-11 connection on Windows 3.1. I think the Arcnet hub is
still kicking around here under a pile in the garage.

Oh man....

I still have some 10Base-5 segments in production. At least I'm using a 7507 with an AUI Ethernet interface processor to drive them, now, instead of the three Proteon P4200's (software to P5600, with IP, EGP, RIP, OSPF, XNS, DNA, X.25, etc) that were used prior. The three P4200's hooked up to each other with ProNET-80 over fiber (using the P3280 counterrotating ring unit). Kindof cool to have floppies with the JNC copyright on them....software release R8.1, 02/06/91. Last time I checked, two of the P4200's still booted up. 2MB of RAM with a 68020 at 16MHz. Sounds like a Cisco AGS.

The fiber portion is now 1000Base-SX and LX, but rather than rewire some areas, we just pop some older switches with AUI 'uplinks' and use the thicknet, which still runs well (as well as thicknet can) after all these years. Some of the areas the thicknet traverses would be a difficult rewire, thanks to 'right-sized' conduit and vampire taps. And if it ain't broke.....

ProNet-80.....TokenRing on steroids. Worked better than the IBM 8220 TR-Fiber boxes, even using the old mini-BNC connectors.

Sorry bro, only Farallon PhoneNet and Gatorboxes here.

What can I say... awesome... :slight_smile: You should definitely send some pictures,
if you can upload them via thicknet :slight_smile:

Sorry no, but I have a Commodore 64 1200/75 baud modem, real collectors item...

If it doesn't have an acoustic coupler, it's not a real collector's item. :slight_smile:
