Just the internal +5 volt regulator, but still get 5 volts into it.  Mine 
is all powered by an external AT power supply, and I am trying to get a 
usable 5 volts into it.  My former method has worked well for nearly 20 
years, until an inetd feedback loop that resulted in about 1000 packets a 
second worth of error messages going both ways overheated and blew the OEM 
one.  Running its internal regulators on +- 12 volts, as opposed to the +- 
8 volts the coco3 supply gave it probably pushed it too close to its 
breakdown.  I may see if the shack has any LM7808 and LM7908 regulators to 
see if I can give it the voltages it expects, which should cool it off when 
traffic gets heavy.  But today, I have to replace the T&P safety valve in 
my water heater, its leaking intermittently.  First things first...

Cheers, Gene
