IBM 5150 Although IBM's launch of the Personal Computer (IBM 5150) in 1981 set the industry standard for personal computing, IBM had introduced a variety of small computers for individual users several years before that. So while now is certainly an appropriate moment to salute the legendary IBM PC on its 20th birthday, it's ... a good time to take a brief look back at some of the pioneering IBM products that immediately preceded it.

IBM Personal Computer The Personal Computer from IBM can be tailored to fit the user's needs. A basic system for home use attached to an audio tape cassette player and a television set would sell for approximately $1,565, in IBM Product Centers, while a more typical system for home or school with a memory of 64,000 bytes, a single diskette drive and its own display would be priced around $3,005. An expanded system for business with color graphics, two diskette drives and a printer would cost about $4,500. The IBM Personal Computer was developed at the Information Systems Division's Boca Raton, Fla, facility and first deliveries will be scheduled for October.

The IBM 610 was the first personal computer, in the sense that it was the first computer intended for use by one person (e.g. in an office) and controlled from a keyboard². The large cabinet contains a magnetic drum, the arithmetic control circuitry, a control panel, and separate paper-tape readers and punches for program and data (according to one former user, Russ Jensen, "The machine was programmed by a punched paper tape which duplicated itself in order to perform extra passes through the code". The IBM electric typewriter printed the output at 18 characters per second; the other device was the operator's keyboard for control and data entry, which incorporated a small cathode ray tube (two inches, 32×10 pixels) that could display the contents of any register [4].
