The Elektor TV Games Computer (TVGC) was a programmable computer system sold by Elektor in kit form from 1979.
 It used the Signetics 2650 CPU with the Signetics 2636 PVI for graphics and sound.
 These were the same chips as used in the Interton VC 4000 console family.
 A 2K monitor ROM written by Philips and a cassette interface were the most important differences between the TVGC and the Interton family.
 Many VC 4000 games were adapted versions of TV Games Computer games.
 It is possible to add cartridge slots to the TVGC to enable it to play console games, and the Hobby Module of the Acetronic console effectively transforms it into a basic TVGC.
The AY-3-8910 is a 3-voice programmable sound generator (PSG) designed by General Instrument in 1978, initially for use with their 16-bit CP1610 or one of the PIC1650 series of 8-bit microcomputers.
 The AY-3-8910 and its variants became popular chips in many arcade games and pinball machines, and were used on, among others, the Intellivision and Vectrex video game consoles, Amstrad CPC, Oric 1, Colour Genie, Elektor TV Games Computer, MSX and Sinclair ZX Spectrum 128/+2/+3 home computers as well as the Mockingboard and Cricket sound cards for the Apple II family.
Tokuji Hayakawa (早川 徳次 , Hayakawa Tokuji , November 3, 1893 - June 24, 1980) was a Japanese businessman and the founder of Hayakawa Kinzoku Kōgyō (the present-day Sharp Corporation).
 He invented and patented the “Tokubijō” belt buckle in 1912 (a belt which can fasten without perforating) and invented the "Ever Ready Sharp" mechanical pencil (from which his company would later get its name) in 1915.
A mechanical pencil (US English) or a propelling pencil (UK English) is a pencil with a replaceable and mechanically extendable solid pigment core called a "lead" .
 The lead, often made of graphite, is not bonded to the outer casing, and can be mechanically extended as its point is worn away.
 Other names include automatic pencil, drafting pencil, technical pencil, click pencil, clutch pencil, leadholder, pen pencil (Indian English), and lead pencil (Bangladeshi English).
Sharp Corporation (シャープ株式会社 , Shāpu Kabushiki-gaisha ) is a Japanese multinational corporation that designs and manufactures electronic products, headquartered in Sakai-ku, Sakai.
 Since 2016 it has been an integral part of Taiwan-based Foxconn Group.
 Sharp employs more than 50,000 people worldwide.
 The company was founded in September 1912 in Tokyo and takes its name from one of its founder’s first inventions, the Ever-Sharp mechanical pencil, which was invented by Tokuji Hayakawa in 1915.
Dr. Grip is a brand of mechanical pencil made by Pilot Pens based in Japan.
 The Dr. Grip style also comes in a pen variety.
 It is well known for its "deflection-deflection/knock system."
 For its ergonomic features, the Dr. Grip pencil has been awarded the Arthritis Foundation's "Commendation for Ease-of-Use."
The Pentel PD345 is a mechanical pencil.
 It was first produced by Pentel in the 1980s, and is now available primarily online.
 Design features include a lead advance button on the side of the pencil body, a housing capable of holding dozens of leads at once, and a relatively wide eraser for heavy erasing.
 Due to the side mounted lead advance button, the pencil was marketed as the "Quicker Clicker" as the user didn't have to stop writing to advance the lead.
Crayola manufactures several different types of colored pencils.
 The most popular one is the standard sharpenable wood-shafted pencil, which also offers the widest range of available colors.
 A smaller and slightly different range of colors is available in mechanical pencil format as part of their "Twistable" product line.
The Yard-O-Led Pencil Company was founded in London, England in 1934 by a Mr Brenner to produce his patent propelling pencils which contained twelve three inch leads (that is to say, 36 inches or a yard of lead).
 After the Second World War the company merged with Sampson Mordan Ltd whose founder had patented the first mechanical pencil in 1822.
 They built a new factory in Birmingham and took over Edward Baker Ltd, another pencil maker.
The Parker Jotter is the Parker Pen Company's second and best-selling retracting refillable ballpoint pen.
 The first was the Hopalong Cassidy ballpoint.
 (Later a fountain pen, mechanical pencil and rollerball pen were introduced to the line.
 However, this entry primarily covers the ballpoint pens identified as the "Jotter").
 As with many other ballpoint pens, it can also be converted into a gel pen by simply changing the refill.
 Since 1954, over 750 million have been sold worldwide.
 It is priced between $6 USD for lower end models, and $20 USD for higher end models, such as special editions.
 Because of its quality, the Jotter has become somewhat of a standard by which ball pens are measured.
 Its refill, originally called the T-Ball (T is for tungsten), had a unique spherical porous metal writing tip now commonly used in the pen industry.
 The pens are also a popular advertising medium and considered a "premium" promotion.
 The external design of the Parker T-Ball refill is a configuration now used by many other brands of refillable pens.
 The Jotter was the preferred pen of President John F. Kennedy
