My 486 was in the basement where my FM radio could barely pick up my favorite station. It had an analog tuner, and I found that if I tuned just off to the edge of the station, I'd get distinctive patterns of interference, just enough to tell how busy the bus was, while still being able to hear the music. It was enough to turn off the monitor and kick back during a long modem download, and the repetitive ticking of what I presume was the UART ISR, could've been the PATA chain, would tell me it was still in progress. When the ticking stopped, the transfer was done and I'd turn the monitor back on and get back to work.
