I have another strange device. This one is called a Channel Tester,
Ser. No. 55263, and a date of 1985-4. It has a series of BNC connectors
on the face labeled "Tx Audio", "RX Audio", "Spk", "Voice Tx Test",
"Voice Rx Test", "Mod", "Disc", "RSSI", "NRZ Data", and "Bit CLock". I
got it attached to an NEC PC 8201A (as I recall) TRS-80 Model 100
clone. It also has a male and female Centronix interface plugs on the
side away from where it attaches to the 8201A. Does anyone have any
idea what this thing is? Thanks!
