The Speak & Math was published in 1980 with a shape identical to both the Speak & Spell and the Speak & Read but with a completely different keyboard layout, different game features, and a different color scheme. Where the American Speak & Spell had been colored red with yellow and orange accents, the American Speak & Math was gray with blue and orange highlights. The Speak & Math was designed to focus on mathematics in children of ages 6–12 with a library of over 100,000 random and preprogrammed problems.
It was regarded as the spiritual successor to TI’s earlier DataMan series[81], with the difference mainly relating to the addition of speech synthesizing software and the visual display. The Speak & Math was only released to American and British markets.
In 1982, a compact version of the Speak & Math was developed contemporaneously with the Speak & Spell Compact. This version was only released in French as Les Maths Magique (lit. The Magical Math). A redesigned version was developed in 1985 for British markets under the name of Maths marvel. This was later released in Italian as Dotto Conta-Parla, in French as le Calcul magique (lit. Magical Calculator), and in German as Mathe-Fix.
The Speak & Math was very minutely redesigned in 1986, under the same name, with the new version representing nothing more substantial than a redesign of the faceplate graphics. In 1990 the Super Speak & Math was released as a major redesign similar to the first version of the Super Speak & Spell. As with the Super Speak & Spell, the display screen of the Super Speak & Math was changed to an LCD screen instead of the former VFD screen.
The keyboard was also expanded and given more functions. The general structure of the console was also altered similarly to the Super Speak & Spell such that the handle which had come at the top of the screen in prior Speak & Math units was now found on the bottom of the toy and ergonomic features were added to the shape.

The Macintosh Plus computer was the third model in the Macintosh line, introduced on January 16, 1986, two years after the original Macintosh and a little more than a year after the Macintosh 512K, with a price tag of 2599 USD. As an evolutionary improvement over the 512K, it introduced RAM expansion from 1 MB to 4 MB, and the SCSI peripheral bus, among smaller improvements. It originally had the same generally beige-colored case as the original Macintosh (“Pantone 453″), but in 1987, the case color was changed to the long-lived, warm gray “Platinum” color.
Introduced as the Macintosh Plus, it was the first Macintosh model to include a SCSI port, which launched the popularity of external SCSI devices for Macs, including hard disks, tape drives, CD-ROM drives, printers, and even monitors.
Its SCSI implementation was engineered shortly before the initial SCSI spec was finalized and, as such, is not 100% SCSI-compliant. As the Mac Plus had no provision at all for expansion other than the SCSI bus, the entire onus of expansion was on the user.
This usually made it very expensive. SCSI ports remained standard equipment for all Macs until the introduction of the iMac in 1998. The Macintosh Plus was the last classic Mac to have a phone cord-like port on the front of the unit for the keyboard, as well as the DE-9 connector for the mouse; later models would use ADB ports.

The Commodore 1084, which was originally developed for the Amiga, is a very good colour monitor for the Commodore 64. With its many ports it can be used for connecting to many home and personal computers and can also be connected to video recorders, picture record players and TV tuners.
The Commodore 1084 has a good, sharp picture with luscious colours. All the important settings can be changed over regulators art the front or the back. While the 1084 only plays mono, the modell Commodore 1084S can also play stereo. Due to its good price performance ratio the 1084 was (and still is) very popular.

The PLA chip (906114-01) used in the Commodore C64 is a generic 82S100 gate array with custom programming.
Its logic functions were dumped and reverse engineered by the community and are available from a variety of sources. This PLA uses the Xilinx CPLD XC9536 to emulate perfectly the PLA of the Commodore 64.

from Wikipedia:
A paddle is a game controller with a round wheel and one or more fire buttons, where the wheel is typically used to control movement of the player object along one axis of the video screen. A paddle controller rotates through a fixed arc (usually about 330 degrees); it has a stop at each end.
The paddle wheel is usually mechanically coupled to a potentiometer, so as to generate an output voltage level varying with the wheel’s angle relative to a fixed reference position. A paddle is thus an absolute position controller. That is, without any previous knowledge, the sensor can be read and the result directly indicates the position of the paddle knob. This is in contrast to a quadrature encoder-based device or “spinner”.

The VIC-20 (Germany: VC-20; Japan: VIC-1001) is an 8-bit home computer which 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.
The VIC-20 was intended to be more economical than the PET computer. It was equipped with only 5 KB of RAM (of this, only 3583 Bytes were available to the user) and used the same MOS 6502 CPU as the PET. The VIC-20′s video chip, the MOS Technology VIC, was a general-purpose color video chip designed by Al Charpentier in 1977 and intended for use in inexpensive display terminals and game consoles, but Commodore couldn’t find a market for the chip. As the Apple II gained momentum with the advent of VisiCalc in 1979, Jack Tramiel wanted a product that would compete in the same segment, to be presented at the January 1980 CES. For this reason Chuck Peddle and Bill Seiler started to design a computer named TOI (The Other Intellect).
The TOI computer failed to materialize, mostly due to the fact that it required an 80-column character display which in turn required the MOS Technology 6564 chip. However, the chip could not be used in the TOI since it required very expensive static RAM to operate fast enough. In the meantime, freshman engineer Robert Yannes at MOS Technology (then a part of Commodore) had designed a computer in his home dubbed the MicroPET and finished a prototype with some help from Al Charpentier and Charles Winterble.
With the TOI unfinished, when Jack Tramiel was confronted with the MicroPET prototype, he immediately said he wanted it to be finished and ordered it to be mass-produced following a limited demonstration at the CES.
