Also tried the 6100 with phonenet adapters between AirTalk and Printer port, no change, as well as switching config to standard printer cable to to modem port, still no change.
Added in SE/30 OS 7.5.5 to AirTalk to the mix (2 AirTalk machines, plus Mini vMac SE), here were the results:
Mini vMac SE FDHD (7.1): can see both machines
SE/30 (7.5.5): Can only see Mini vMac SE
6100 (8.1): Can’t see any other machines
Out of curiosity, I decided to try my only other NuBus based PPC machine, a PowerBook 5300ce running 8.6 in place of the 6100 on this test network. These were the results:
Mini vMac SE FDHD: could see other two
SE/30: could see other two
5300ce: could see other two
I was able to connect from Mini vMac to 5300ce, push a file to it, then connect from 5300ce to SE/30 and push said file to that machine. So it worked as both host and client. Seems to only be a 6100 issue.
Seems to work excellent aside from the 6100
Let me know if you need me to try anything else with the 6100.
