Floppy disk
Mauch and his wife Lucy started what was originally PerCom Data that same month, selling the "CIS-30" adaptor allowing any portable cassette player to be connected to the Motorola 6800-based micros from SWTPC. The CIS-30 was a success, and soon followed by similar devices for other platforms. Floppy disk drives followed, along with rapid growth. Percom incorporated (dropping the capital C in the name) in 1978.
