Bil Herd is a computer engineer who created several designs for 8-bit home computers while working for Commodore Business Machines in the early to mid-1980s.
He attended the Indiana school system. [1] Herd did not have a college degree, and did not graduate high school, though he was working as an engineer by the age of 20.

After first acting as the principal engineer on the Commodore Plus/4, C16/116, C264, and C364 machines, Herd designed the significantly more successful Commodore 128, a dual-CPU, triple-OS, compatible successor to the Commodore 64. Prior to the C128, Herd had done the initial architecture of the Commodore LCD computer, which was not released. [2]
After leaving Commodore, Herd continued to design faster and more powerful computers with emphasis on machine vision and is a co-author on a patent involving n-dimensional pattern matching. He also designed an ultrasonic backup sensor for vehicles while working for Indian Valley Mfg. in 1986, a feature found on many modern vehicles today.[ citation needed ]

Herd has undertaken an entrepreneurial role and is owner of several small companies. As for recent low-level computer hacking, he did a "cameo appearance" by contributing a snippet of sprite logic code to the C64 DTV product designed by Jeri Ellsworth.
Herd appeared in and narrated the documentary "Growing the 8 Bit Generation" (a.k.a. "The Commodore Wars") about the early days of Commodore and the home computers explosion. Subsequently, he narrated the documentary "Easy to learn, hard to master: the fate of Atari", thus becoming the official voice of the "8-bit Generation" documentary series. As of September 2020, [update] he produces videos for Hackaday .
In 2021, Herd co-authored a book with Margaret Morabito, Back into the Storm: A Design Engineer's Story of Commodore Computers in the 1980s, in which he recounts inside stories about his and his team's experiences with designing computers for Commodore.
Atari ST is a line of personal computers from Atari Corporation and the successor to the Atari 8-bit family. The initial model, the Atari 520ST, had limited release in April–June 1985, and it was widely available in July. The ST was the first personal computer with a bitmapped color graphical user interface, using a version of Digital Research's GEM interface / operating system, from February 1985.
The Commodore 64, also known as the C64, is an 8-bit home computer introduced in January 1982 by Commodore International. It has been listed in the Guinness World Records as the highest-selling single computer model of all time, with independent estimates placing the number sold between 12.5 and 17 million units. Volume production started in early 1982, marketing in August for US$595. Preceded by the VIC-20 and Commodore PET, the C64 took its name from its 64 kilobytes(65,536 bytes) of RAM. With support for multicolor sprites and a custom chip for waveform generation, the C64 could create superior visuals and audio compared to systems without such custom hardware.
Commodore International was an American home computer and electronics manufacturer founded by Jack Tramiel. Commodore International (CI), along with its subsidiary Commodore Business Machines (CBM), was a significant participant in the development of the home computer industry in the 1970s to early 1990s. In 1982, the company developed and marketed the world's second-best selling computer, the Commodore 64, and released its Amiga computer line in July 1985. Commodore was one of the world's largest personal computer manufacturers, with sales peaking in the last quarter of 1983 at $49 million.
Jack Tramiel was an American businessman and Holocaust survivor, best known for founding Commodore International. The Commodore PET, 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. He was one of 6 people spotlighted when the computer was denoted "Machine of the Year" by Time magazine in 1982.
The Commodore 128, also known as the C128, C-128, or C= 128, is the last 8-bit home computer that was commercially released by Commodore Business Machines (CBM). Introduced in January 1985 at the CES in Las Vegas, it appeared three years after its predecessor, the Commodore 64, the bestselling computer of the 1980s. Approximately 2.5 million C128s were sold during its four year production run.
The VIC-20 is an 8-bit home computer that was sold by Commodore Business Machines. The VIC-20 was announced in 1980, roughly three years after Commodore's first personal computer, the PET. The VIC-20 was the first computer of any description to sell one million units. It was described as "one of the first anti-spectatorial, non-esoteric computers by design...no longer relegated to hobbyist/enthusiasts or those with money, the computer Commodore developed was the computer of the future."
The Commodore 16 is a home computer made by Commodore International with a 6502-compatible 7501 or 8501 CPU, released in 1984 and intended to be an entry-level computer to replace the VIC-20. A cost-reduced version, the Commodore 116, was mostly sold in Europe.
The Commodore Plus/4 is a home computer released by Commodore International in 1984. The "Plus/4" name refers to the four-application ROM-resident office suite ; it was billed as "the productivity computer with software built in".
Commodore BASIC, also known as PET BASIC or CBM-BASIC, is the dialect of the BASIC programming language used in Commodore International's 8-bit home computer line, stretching from the PET (1977) to the Commodore 128 (1985).
PETSCII, also known as CBM ASCII, is the character set used in Commodore Business Machines' 8-bit home computers.
The 8563 Video Display Controller (VDC) was an integrated circuit produced by MOS Technology. It was used in the Commodore 128 (C128) computer to generate an 80-column RGB video display, running alongside a VIC-II which supported Commodore 64-compatible graphics. The DCR models of the C128 used the later and more technically advanced 8568 [D]VDC controller.
The Commodore RAM Expansion Unit (REU) is a range of external RAM add-ons.
The C64 Direct-to-TV, called C64DTV for short, is a single-chip implementation of the Commodore 64 computer, contained in a joystick, with 30 built-in games. The design is similar to the Atari Classics 10-in-1 TV Game. The circuitry of the C64DTV was designed by Jeri Ellsworth, a computer chip designer who had previously designed the C-One.
BASIC 8 – "The Enhanced Graphics System For The C128" – was an American-designed graphics system developed by Walrusoft of Gainesville, Florida and published in 1986 by Patech Software of Somerset, New Jersey. The system was an extension of Commodore's BASIC 7.0 for the C128 home/personal computer. BASIC 8.0 provided commands lacking in BASIC 7.0 to generate (color) graphics in the C128's high-resolution 80-column mode for RGB monitors.
The C-One is a single-board computer (SBC) created in 2002 as an enhanced version of the Commodore 64, a home computer popular in the 1980s. Designed by Jeri Ellsworth and Jens Schönfeld from Individual Computers, who manufactured the boards themselves, the C-One has been re-engineered to allow cloning of other 8-bit computers.
Jeri Janet Ellsworth is an American entrepreneur, computer chip designer and inventor. She gained fame in 2004 for creating a complete Commodore 64 emulator system on a chip housed within a joystick, called Commodore 30-in-1 Direct to TV. It runs 30 video games from the 1980s, and at peak, sold over 70,000 units in a single day via the QVC shopping channel.
GEOS is a discontinued operating system from Berkeley Softworks. Originally designed for the Commodore 64 with its version being released in 1986, enhanced versions of GEOS later became available in 1987 for the Commodore 128 and in 1988 for the Apple II series of computers. A lesser-known version was also released for the Commodore Plus/4.
Amiga Corporation was a United States computer company formed in the early 1980s as Hi-Toro. It is most famous for having developed the Amiga computer, code named Lorraine.
Shiraz Shivji was the primary designer of the 1985 Atari ST computer, and one of the engineers of the Commodore 64.
Scene World Magazine is a disk magazine for the Commodore 64 home computer. The magazine has been released regularly since February 2001.
