I think you mean that the trucks had Positive ground, and it was a good day 
when some clown at the trucking co would start swapping radios without 
thinking to move the plug

the Mocom 70's had the plug-in adapter (TLN 4824 ????) for + ground

and yes, Micors sucked, big time......the radio technology was about 15 
years ahead of the contact technology

some other remembrances:

remember the Base Station Power Supply for Maxars ?

the one that would put out 22 volts when the pass transistors shorted ? 
which would take out the driver xistor in the radio ? quick and easy fixes

or antenna relays in Micor bases ?  take off the little spring clip, slip 
the guts of a Mocom 70 relay in there, and done; then send re-assemble the 
Mocom relay and send it in for a freebie replacement ?

or that crappy slide-type 'PL on-off' switch in the Business Dispatchers ? 
that you had to totally disassemble the front of the unit and drill out the 
rivets to change ?

or the first time you didn't get a Micor base plate absolutely level and the 
radio jammed on it and the handle mechanism broke when you forced it ?

programming the control heads in VHF or UHF mobile phones ?

programming the number into the phones ?

including the big fold-out number-recognition board in the old TLD-1220 
tube-tx mobiles ?  the one with a gazillion discrete transistors on it and 
those jumper wires ?

or (God forbid) trying to fix a 'Flexar' base that got hit by a God-Zot® ?

we'll slam GE's (except Mastr I's ) the next time
