The PCradio was a notebook computer released by International Business Machines (IBM) in late 1991. [4] Designed primarily for mobile workers such as service technicians, salespersons and public safety workers, the PCradio featured a ruggedized build with no internal hard disk drive and was optioned with either a cellular or ARDIS RF modem, in addition to a standard landline modem. [5] [6]

Components

The internals of the PCradio were encased in a slate-gray, [7] hardened plastic case, which IBM said was resistant to heat, moisture, impact and certain chemicals. Its port doors, connectors, and keyboard were designed to be water-resistant through the use of gaskets, seals, and O-rings. [5] It featured a monochrome LCD capable of rendering graphics in CGA mode and text at 80 columns by 25 lines. The laptop was powered by either a nickel–cadmium battery or a wall or car power adapter. [5] [8]

To keep the PCradio ruggedized, IBM offered SRAM modules of various capacities up to 2 MB for file storage, in lieu of a mechanical hard disk drive. [2] [3] Special versions of Siega System's One-Button Mail, an e-mail client, [7] Traveling Software's Battery Watch, a battery management application, and LapLink, a file transfer program, were developed with drivers to support the PCradio's special hardware. [9] The latter, renamed to Notebook Manager, came bundled with the PCradio as a ROM module. [2] Owing to its ruggedized nature, the PCradio could operate between 32 degrees and 132 degrees Fahrenheit. [3] A thermal printer which accepted paper 3-1/8 inches in diameter was optional. [8]

The cellular model was capable of sending and receiving faxes, [10] at a rate of 9.6 KB per second—twice that of its cellular data speed of 4.8 KB per second. [3] Meanwhile the landline model was capable of sending but not receiving faxes, and the ARDIS model could not receive faxes whatsoever. [10] The cellular model could also be used for voice communications with the optional handset. [3]

Development

The PCradio project was helmed by Robert A. Lundy, a director and general manager in charge of the wireless business unit of IBM's Industry Products Group facility Boca Raton, Florida. [11] The project commenced in 1989 and comprised a team of 25 people in Boca Raton, including Lundy. [12] They hired Vadem, an original design manufacturer from San Jose, California, as a consultant on the project. [13] IBM reportedly spent $50 million in development costs. [1] The PCradio was ultimately manufactured at IBM's North Carolina and Scotland facilities, with the cellular modem made by Novatel Communications at their Lethbridge, Alberta, factory and IBM's Don Mills, Toronto, facility. [14] The ARDIS modem, meanwhile, was manufactured by Motorola and designed at their Richmond, British Columbia, facility. This ARDIS modem was designed to consume less power than conventional data radios, enabling the PCradio's battery to last longer on a charge. [15]

A month before its FCC approval in December 1991, [4] McCaw Cellular forged a relationship with IBM to become the first carrier of the cellular model of PCradio. [16] Coverage eventually expanded to other carriers operated by the Regional Bell Operating Companies, [17] including BellSouth. [18]

Reception

One analyst saw a large market for the PCradio and other digital wireless devices, [10] which IBM hoped to dominate similar to how they captured the personal computer market with the IBM PC in the early 1980s. [7] According to Robert R. Daly, a product manager of the Boca Raton facility, the company expected to sell up to 100,000 units in two years. [12] However, only slightly fewer than 10,000 units of the PCradio were sold by August 1994. [1] Among the few and first to use it was Sears, whose service technicians in California used the PCradio to receive timely updates to parts availability and prices from 1992 until 1994, when they replaced it with a more powerful unit produced by Itronix. [19] Several police departments and emergency services in the United States also used the PCradio, [1] including the Baltimore Police Department, who purchased a fleet of PCradios for their officers and dispatchers, where it was used to call up vehicle information and map directions and send and receive incident reports. The Department also used it for making discreet reports of drug dealings, instead of having to use the vocal police radio channels to which dealers often had scanners tuned—fleeing the scene if an officer made a description of their likeness. [20]

IBM discontinued the PCradio in 1993, [21] and in August 1994, they sold their remaining stock, parts and tooling to Aspen Marine Group of West Palm Beach, Florida, where they rebadged the unsold PCradios under their Aptek sub-brand and sold an equivalent model targeting the same market. [1] The same month, IBM released the Simon, a BellSouth-powered cellular PDA that could place phone calls and access the Internet. [22]

<span class="mw-page-title-main">IBM PS/2 Model 25</span> Personal computers

The Personal System/2 Model 25 and its later submodels the 25 286 and 25 SX are IBM's lowest-end entries in the Personal System/2 (PS/2) family of personal computers. Like its sibling the Model 30, the Model 25 features an Industry Standard Architecture bus, allowing it to use expansion cards from its direct predecessors, the PC/XT and the PC/AT—but not from higher entries in the PS/2 line, which use Micro Channel. Unlike all other entries in the PS/2 line, the Model 25 and its submodels are built into an all-in-one form factor, with its cathode-ray tube (CRT) monitor and system board occupying the same enclosure. IBM oriented the Model 25 at home office workers and students.

The LTE line proved highly popular—Compaq selling hundreds of thousands of units between the three—and gave way to successive generations of the line, including the LTE Lite, the LTE Elite, and the LTE 5000 series. With its use of industry-standard floppy and hard drive technologies, the LTE was the first commercially successful IBM PC–compatible notebook and helped launch the fledgling PC notebook industry, which had seen earlier attempts fail due to the use of novel but nonstandard data storage.

<span class="mw-page-title-main">Data General Walkabout</span>

The Walkabout is a family of notebook-sized laptops introduced by Data General in 1989 and discontinued in 1993. The first entry in the line, simply named the Walkabout, was a battery-powered portable terminal capable of emulating multiple protocols; as well, it contains a rudimentary word processor, an autodialer utility for placing phone calls, and a real-time clock display and timer application for setting reminders. The successor to the first model, the Walkabout/SX, released in 1990, was an architectural redesign allowing the laptop to be used as a general-purpose IBM PC compatible. The penultimate entry, the Walkabout/320, increased its predecessor's i386SX processor clock speed from 16 MHz to 20 MHz, while the last entry in the line, the Walkabout/386SL, replaced the processor with Intel's portable-centric i386SL processor clocked at 25 MHz.
