TYPIT® - Special Typewriter Symbols

|||||||||||||
RF Cafe visitor Rick M. was kind enough to send me this message and info re the TYPIT® product: "Years ago you posted about Typit, these accessories for typing scientific characters. My father was a physics prof and academic dean at a small college in Kansas, which apparently made him a prospective customer for them. In Dad's papers I found their materials and a sample Typit. Just thought you might be interested." Turns out using them is different that what I had envisioned, involving replacing keys. It is actually a very convenient scheme with no key replacement required. See Mechanical Enterprises, and this PDF (p7) If you are typing on your computer or phone (which is actually more of a computer than a phone) and you need to create a character other than the standard keyboard set, most programs provide a means to access extended characters either with a menu selection or an ability to enter ASCII extended character set codes into the source code. At most, it takes a couple additional keystrokes (assuming you know how to do it). Back in the days of typewriters, the task was nowhere near as easy. Some manufacturers of typewriters had replaceable balls for allowing a variety of typefaces and fonts, often including one with special science and engineering characters. Those required the typist to reserve space on the page for the characters, swap out the ball, then go back and fill in the blanks. It was tedious and error-prone. There is often a noticeable shift in the character baseline compared to all the rest in the line. The Mechanical Enterprises company produced an add-on gadget called the TYPIT that needed to be attached to the typewriter and allowed interchangeable character die to be quickly inserted and removed as the need required. More than a thousand characters were available. See page 7 of this document for a little more info on TYPIT. TYPIT® AdRon Mingo - World's fastest mechanical typewriter typist @ 180 wpm!
