The Commodore 2031 and Commodore 4031 are single-unit 5¼" floppy disk drives for Commodore International computers.
 They use a similar steel case form to the Commodore 9060/9090 hard disk drives, and use the parallel IEEE-488 interface common to Commodore PET/CBM computers.
 Essentially, both models are a single-drive version of the Commodore 4040.
Commodore International (or Commodore International Limited) was a North American home computer and electronics manufacturer.
 Commodore International (CI), along with its subsidiary Commodore Business Machines (CBM), participated in the development of the home–personal computer industry in the 1970s and 1980s.
 The company developed and marketed the world's best-selling desktop computer, the Commodore 64 (1982), and released its Amiga computer line in July 1985.
The Commodore MAX Machine, also known as Ultimax in the United States and VC-10 in Germany, was a home computer designed and sold by Commodore International in Japan, beginning in early 1982, a predecessor to the popular Commodore 64.
 The Commodore 64 manual mentions the machine by name, suggesting that Commodore intended to sell the machine internationally; however, it is unclear whether the machine was ever actually sold outside Japan.
 It is considered a rarity.
The Commodore LCD (sometimes known in short as the CLCD) was a LCD-equipped laptop made by Commodore International.
 It was presented at the January 1985 Consumer Electronics Show, but never released.
 The CLCD was not directly compatible with other Commodore home computers, but its built-in Commodore BASIC 3.6 interpreter could run programs written in the Commodore 128's BASIC 7.0, as long as these programs did not include system-specific POKE commands.
 Like the Commodore 264 and Radio Shack TRS-80 Model 100 series computers, the CLCD had several ROM-based office application programs.
The Commodore 1541 (also known as the CBM 1541 and VIC-1541) is a floppy disk drive which was made by Commodore International for the Commodore 64 (C64), Commodore's most popular home computer.
 The best-known floppy disk drive for the C64, the 1541 is a single-sided 170-kilobyte drive for 5¼" disks.
 The 1541 directly followed the Commodore 1540 (meant for the VIC-20).
Jack Tramiel ( ; Polish: Jacek Trzmiel ; December 13, 1928 – April 8, 2012) was a Polish American businessman, best known for founding Commodore International.
 The Commodore PET, Commodore VIC-20 and Commodore 64 are some home computers produced while he was running the company.
 Tramiel later formed Atari Corporation after he purchased the remnants of the original Atari, Inc. from its parent company.
Geniac was an educational toy billed as a "computer" designed and marketed by Edmund Berkeley, with Oliver Garfield from 1955 to 1958, but with Garfield continuing without Berkeley through the 1960s.
 The name stood for "Genius Almost-automatic Computer" but suggests a combination of the words genius and ENIAC (the first fully electronic general-purpose computer).
The Commodore 8050, Commodore 8250, and Commodore SFD-1001 are 5¼-inch floppy disk drives manufactured by Commodore International, primarily for its 8-bit CBM and PET series of computers.
 The drives offered improved storage capacities over previous Commodore drive models.
The Hyperion is an early portable computer that vied with the Compaq Portable to be the first portable IBM PC compatible.
 It was marketed by Infotech Cie of Ottawa, a subsidiary of Bytec Management Corp., who acquired the designer and manufacturer Dynalogic in January 1983.
 In 1984 the design was licensed by Commodore International in a move that was forecast as a "radical shift of position" and a signal that Commodore would soon dominate the PC compatible market.
 Despite computers being "hand-assembled from kits" provided by Bytec and displayed alongside the Commodore 900 at a German trade show as their forthcoming first portable computer, it was never sold by Commodore and some analysts downplayed the pact.
 The Hyperion was shipped in January 1983 at C$4995, two months ahead of the Compaq Portable.
The Commodore 8280 were dual unit 8" floppy disk drives for Commodore International computers.
 They used a wide rectangular steel case form similar to that of the Commodore 4040, and used the parallel IEEE-488 interface common to Commodore PET/CBM computers.

Question: Did Edmund Berkeley market both Geniac and Commodore International ?
