An XT class luggable of mine had a Memory/RTC/GamePort/Parallel/Serial/InternalModem card installed when I acquired it. Some research on the card showed it was released in 1986. If they were being put on multifunction cards then the market had to already have been full of dedicated cards. I was around and using modems at the time but really don't remember the brief era of 1200 baud modems. The family TRS-80 Model 1 had a Novation CAT 300 attached which my father's work let him take home when they disposed of it around 1980. In the mid-80's my C64 used a 300 baud Commodore 1660 modem. Next thing I remember, I was shoving an internal 2400 baud modem into a new Packard Bell PB500 XT class machine. That modem got well used.
