It wasn't so much reading the cards in as the noise from the MFCU when it punched. Remember, those old phones had so much metal & plastic on them they were quite well shielded. We use to use radios to set upon the 360/25 series running in 1401 emulation mode and read card decks in to play Christmas carols. Phil

Was the provided radio (next to the phone) loud enough to hear with the machine feeding cards in? Or was it used to hear an infinite loop (how long did those take back then?) like I hear my cell phone on the el-cheapo PC speaker set... Rob - that machine was running years before I could :-)
