Telxon RFC30
The RFC30 was a big brother RF base station in the Telxon Range.
I’ve not been able to find anything to substantiate my recollections here, but I believe the RFC30 used a G-TACS Radio element rather than E-TACS. As with the RFC330 the RFC30 connected to a host using an RS232 connection, and would work with standard Telxon API’s on both the host and the PTC range.
