Overview
Smoke Signal Broadcasting, Inc. was an American computer company founded in 1976 by Frederic Jerome "Ric" Hammond in Hollywood, California. Although Hammond initially established the business as a consulting operation for radio and other broadcasting organizations, it rapidly moved into the emerging personal and business-computing market. The company became one of the earliest independent suppliers of expansion hardware for the Southwest Technical Products Corporation 6800, a Motorola 6800-based computer built around the SS-50 bus. Smoke Signal's first major product was the M-16-A, a 16 KB static-random-access memory board introduced in 1976. It was described in contemporary coverage as the first expansion board made independently of SWTPC for the SWTPC 6800. Strong demand for the board pushed the company away from broadcasting consultancy and toward computer hardware. In 1978, Smoke Signal introduced the BFD-68 floppy-disk system, which could house as many as three 5.25-inch drives and included a controller and OS-68 disk operating system. OS-68 provided a random-access file system and became a foundation of the company's later systems. The success of the BFD-68 led to Smoke Signal's own computer line, the Chieftain. The original Chieftain used the Motorola 6800, included SS-50 compatibility, and was supplied as an assembled machine rather than a kit. Its design emphasized reliability, with features such as cooling and gold-plated edge connectors, and it was marketed both to technically oriented hobbyists and to professional users. Commercial customers included Hughes Aircraft and Western Electric, which used Chieftain systems in industrial process-control applications. Smoke Signal also produced the SCB-68 single-board computer, which retained the 6800 architecture while offering expansion options for memory, communications, timing, and mathematical processing. During the early 1980s, the company shifted toward business systems. The Chieftain Business System replaced the 6800 with Motorola's 6809, increased memory capacity, added support for larger disk configurations and a Winchester hard disk, and was sold with business-oriented peripherals. The Chieftain 9822 followed in 1982. It supported multiple storage configurations and could run either Smoke Signal DOS, an updated OS-68 implementation, or Microware's OS-9 multitasking and multi-user operating system. Benchmarking organizations rated the 9822 strongly in scientific computing and data processing, but reviewers criticized the company's dependence on dealers to supply or commission much of the application software customers needed. Smoke Signal expanded internationally through dealers, equipment fabricators, rebadging arrangements, and regional partnerships. The Chieftain Business System was sold in New Zealand under the Econz name, and a joint venture with Medco Electronics marketed Smoke Signal systems in Pakistan under the Pakistan Computers name. The company later pursued Unix-oriented systems, including the VAR/68 using OS-9 and the VAR/68K, a Motorola 68000-based computer marketed as Unix-compatible and supplied with the Regulus operating system. The business weakened in the mid-1980s as the computer industry changed and Smoke Signal struggled with scale, software distribution, and competition. Its workforce and asset base contracted, and by 1987 Hammond had moved the company to Thousand Oaks and redirected his attention toward a real-estate venture. Smoke Signal was reduced largely to a support operation for existing customers. Hammond filed the company's final corporate statement in 1991, ending its independent business existence. The company remains historically notable as an early third-party SWTPC expansion supplier and as an early manufacturer of multi-user computer systems.
History
Ric Hammond founded Smoke Signal Broadcasting in 1976 in Hollywood while working as a programming director at CBS Radio's KNX-FM in Los Angeles. His original plan was to provide consulting services to broadcasting organizations, reflecting his longstanding interest in radio. Hammond had also developed an interest in computers and had studied computer construction at the board level. When he noticed that users of the popular SWTPC 6800 lacked sufficient memory and peripheral options for its SS-50 bus, he designed the M-16-A, a 16 KB static-RAM expansion board. The M-16-A's success quickly changed the company's direction. By 1977, Smoke Signal was concentrating on SWTPC-compatible expansions. In 1978, it released the BFD-68 floppy-disk system, supporting up to three 5.25-inch drives in one enclosure. The system included a controller and OS-68, a disk operating system that gave the SWTPC 6800 random-access file handling. The product's reception encouraged Smoke Signal to build complete computers. After relocating to Westlake Village, California, the company released the original Chieftain, a Motorola 6800 system with SS-50 compatibility, expandable memory, multiple serial connections, floppy-disk options, and an 80-by-25 character display. Unlike many contemporaries that sold kits, Smoke Signal supplied the Chieftain assembled. Hammond believed this could appeal both to hobbyists seeking convenience and to professional buyers who did not want to build their own systems. The machine emphasized durability through features such as a cooling fan and gold-plated edge connectors. Its customers included industrial and aerospace-related organizations, including Hughes Aircraft and Western Electric. In 1979, the company added the SCB-68 single-board computer, retaining the 6800 architecture while permitting additional memory, EPROM, communications, timing, and mathematical hardware. At the beginning of the 1980s, Smoke Signal moved more deliberately into business computing. The Chieftain Business System used Motorola's 6809 processor, supported substantially more memory, and added larger disk configurations, a Winchester hard drive, a printer, and a terminal. In 1982, the Chieftain 9822 refined this platform. It offered alternative floppy and Winchester configurations and could run Smoke Signal DOS or OS-9, Microware's multitasking and multi-user operating system. The system performed well in contemporary benchmark comparisons, particularly in scientific computing and data processing. However, software availability was a persistent weakness. Smoke Signal increasingly relied on its dealer network to supply applications, and local dealers often lacked generalized software or had to commission programs for individual customers. Software had initially been a competitive strength. The company sold OS-68 applications under its own branding, licensed products from outside developers, and offered tools including BASIC, an editor, an assembler, a word processor, and a disassembler. Roger Embree led the software division and developed OS-68. By 1982, Smoke Signal had transferred much of the software burden to approximately 120 dealers through an exchange coordinated by Deborah Conrad and supported by an internal MicroCobol database. The arrangement was intended to help dealers share software, but it did not solve the company's broader distribution and development problems. Smoke Signal developed an international channel during the early 1980s. Dealers and fabricators operated across Australia, Asia, Europe, South Africa, and the United States. A New Zealand company rebadged the Chieftain Business System as the Econz, and Smoke Signal formed a partnership with Medco Electronics to market systems in Pakistan under the Pakistan Computers name. The company also expanded its operating-system ambitions. The VAR/68 used OS-9, while the 1984 VAR/68K used Motorola's 68000 family and Regulus, an operating system described as Unix-compatible. The company's position deteriorated in the middle of the decade. Its employment, assets, and commercial momentum declined despite the technical strengths of the later systems. In 1987, Smoke Signal moved to Thousand Oaks, California. Hammond incorporated a separate real-estate company and relegated Smoke Signal to a support role for installed customers. The real-estate venture was subsequently damaged by the collapse of the Ventura County housing market. Smoke Signal's last corporate statement was filed in 1991. Hammond later returned to radio-related work as a disc jockey and traffic reporter before his death in 2012.
