Practical Peripherals, Inc., was a private American computer peripheral manufacturer active from 1981 to 1999 and based in Los Angeles County. Founded by Michael Seedman, the company specialized in telecommunications products, primarily modems, for personal computers. Seedman led the company from its inception in 1981 until 1993, after Practical Peripherals was sold to Hayes Microcomputer Products.
The company ventured into the market with print buffers under the Microbuffer brand, offering various forms tailored for different systems and needs. Around 1985, the company expanded its product line by introducing modems, under the brand name Practical Modem (PM). In 1989, Practical was acquired by Hayes, who kept the company around as a subsidiary until 1999, when Hayes themselves were bought out by Zoom Telephonics.
