The network technology was basic 10B2 ETHERNET on 50 ohm coax cables with strict rules on terminations and more. THAT hub has 10BT connections for other machines with a single 10B2 port which acted as a translator from 10BT to 10B2 networks.
These are not too rare in the used market but I rarely found them to die. What I did find was owners and networking admins that had forgotten how to wire and terminate 10B2 networks. Far be it for me to duplicate that here as today you can get that on the web.
I'd recheck my 10B2 network cables and terminations to see if something was undone.
I have an old but still very good Apple LaserWriter 16/600 PS printer that is shared by several computers in different rooms in our home. It has been connected from its SCSII (13 pin) port by an Asante FriendlyNet with a (I think its called BNC) connector. A cable with a connector attaches to it and goes to a MacSense PalmHUB-9E with a T-shaped connector. The problem is the hub seems to dying and MacSense has discontinued it and I don't think anybody makes that kind of hub anymore. My choice would seem to be throw away a really good printer or change the setup. Is there any way to connect that SCSII port to USB or someother current system? Or something that can connect that FriendlyNet that I have? Our computers are a G4 tower, a G5 tower and a G4 iMac. Any ideas would be greatly appreciated.
