The Apple IIGS (stylized as IIGS) is the fifth and most powerful model in the Apple II series of personal computers produced by Apple Computer. The “GS” in the name stands for Graphics and Sound, referring to its enhanced multimedia capabilities, especially its state-of-the-art sound and music synthesis, which greatly surpassed previous models of the line and most contemporary machines like the Macintosh and IBM PC.
The machine was a radical departure from any previous Apple II, with its true 16-bit architecture, increased processing speed, direct access to megabytes of RAM, wavetable music synthesizer, graphical user interface, and mouse. While still maintaining full backwards compatibility with earlier Apple II models, it blended the Apple II and aspects of Macintosh technology into one. Keeping with Apple’s “Apple II Forever” slogan of the time, the IIGS set forth a promising future and evolutionary advancement of the Apple II line, but Apple paid it relatively little attention as the company increasingly focused on the Macintosh platform.
The Apple IIGS was the first computer produced by Apple to use a color graphical user interface, as well as the “Platinum” (light grey) color scheme and the Apple Desktop Bus interface for keyboards, mice, and other input devices. It was also the first personal computer to come with a built-in “wavetable” sample-based synthesizer chip, utilizing technology from Ensoniq. The machine outsold all other Apple products, including the Macintosh, during its first year in production.

I thank my dear friend that gave me the Atari Touch Tablet.
Autopsy:
The Atari Touch Tablet was a well designed and brilliant idea. Giving the user the ability to use a virtual sheet of paper and pen, they could draw, drag and drop, paint and erase images with the included Atari Artist program.
Perhaps given more time, the Touch Tablet could have been used for many other innovative ideas and perhaps vertical market applications. The Atari CX-77 Touch Tablet was designed by Tom Palecki formerly of Atari’s Industrial Design group.

The Philips Monitor CM8802/00G is an excellent RGB monitor 14” suitable to use with Amiga and Atari ST.
Electronically is identical to the monitor Philips CM 8833, but compared to the latter one we can’t find the TTL RGB (DIN) input and the switching for Color/Monochrome, but is always present the composite (RCA) and Audio which makes it perfectly for computers with this type of output.

SNDH archive v4.3 released - 4107 SNDH files (total 7719 tunes)
Ever since the birth of the Atari ST, different chip music formats have had different ways to use them. If you are coding a chip music player for the Atari ST you would have to use dozens and dozens of special ways to replay music.
But in the mid 90′s, BDC of Aura crew became tired of this inelegant system and decided to fix the issue once and for all. He then created the ‘SNDH’ file format. SNDH is actually the original songfile and replaycode with a header bolted on top of the music and replayer. The header has a unified calling interface no matter what type of chip music is hidden beneath it, and it has extended datas about the music.

This version of Coleco Vision SECAM (Péritel/Euroconnector) uses a PCB 91162 REV D which differs from the classical version with PCB 91209 because integrates an internal video encoder from Y (BY) (RY) to RGB which is separate from the motherboard.
This makes think that in theory all PAL versions that use the VDP 9929A with PCB 91162 REV D and RF output can be modified to have a RGB output signal by adding this external video encoder.

The ColecoVision is Coleco Industries’ second generation home video game console, which was released in August 1982. The ColecoVision offered near-arcade-quality graphics and gaming style along with the means to expand the system’s basic hardware. Released with a catalog of 12 launch titles, with an additional 10 games announced for 1982, approximately 145 titles in total were published as ROM cartridges for the system between 1982 and 1984. River West Brands currently owns the ColecoVision brand name.
In 2009, IGN named the ColecoVision their 12th best video game console out of their list of 25, citing “its incredible accuracy in bringing current-generation arcade hits home.”
Coleco licensed Nintendo’s Donkey Kong as the official pack-in cartridge for all ColecoVision consoles, helping to boost the console’s popularity. By Christmas of 1982, Coleco had sold more than 500,000 units, in part on the strength of its bundled game. The ColecoVision’s main competitor was the arguably more advanced but less commercially successful Atari 5200.
The ColecoVision was distributed by CBS Electronics outside of North America, and was branded the CBS ColecoVision.
Sales quickly passed 1 million in early 1983, before the video game crash of 1983. By the beginning of 1984, quarterly sales of the ColecoVision had dramatically decreased.
Over the next 18 months, the Coleco company ramped down its video game division, ultimately withdrawing from the video game market by the end of the summer of 1985. The ColecoVision was officially discontinued by October 1985. Total sales of the ColecoVision are uncertain but were ultimately in excess of 2 million units, as sales had reached that number by the spring of 1984, while the console continued to sell modestly up until its discontinuation the following year.
In 1986, Bit Corporation produced a ColecoVision clone called the Dina, which was sold in the United States by Telegames as the Telegames Personal Arcade.

The Intellivision is a video game console released by Mattel in 1979. Development of the console began in 1978, less than a year after the introduction of its main competitor, the Atari 2600. The word intellivision is a portmanteau of “intelligent television”. Over 3 million Intellivision units were sold and a total of 125 games were released for the console.
In 2009, video game website IGN named the Intellivision the No. 14 greatest video game console of all time. It became Mattel’s first video game console, though it was their only console until the release of the HyperScan in 2006.
The Intellivision was developed by Mattel Electronics, a subsidiary of Mattel formed expressly for the development of electronic games. The console was test marketed in Fresno, California, in 1979 with a total of four games available, and was released nationwide in 1980 with a price tag of US$299 and a pack-in game: Las Vegas Poker & Blackjack. Though not the first system to challenge Atari, it was the first to pose a serious threat to Atari’s dominance. A series of advertisements featuring George Plimpton were produced, that demonstrated the superiority of the Intellivision’s graphics and sound to those of the Atari 2600, using side-by-side game comparisons.

Introduced CES 1978
Hardware 6504 CPU (28-pin 6502, 8K addressable memory, on-chip clock, IRQ line only) @ 1MHz, 6530 RIOT (64 bytes RAM, 1KB ROM, 2 I/O ports, 8-bit timer), 6332 ROM. Two ROM sockets; the 6332 is occupying only one of them. The 6504 is socketed; the remainder are soldered directly to the board.
Graphics and Sound If you can call it that. Four 7-element LED displays for the timers and four dome indicator LEDs. Piezoelectric beeper.
Eventual Fate Released summer 1978 in USA, UK and West Germany.
This chess machine is an 22 x 16 x 5cm (rear, approximately 8 x 6 x 2 inch; front is 3.5cm/1.2 inches high) machine, off-white (similar to early VIC-20s), with a dark brown base. The 7-element LEDs are in groups of two, one labeled “FROM (Time white)” and the other “TO (Time black)”; the four dome LEDs are labeled “Check”, “CHESSmate LOSES”, “CHESSmate IS PLAYING WHITE” and “CHESSmate IS PLAYING BLACK”.
The “keyboard” is a membrane setup (similar to the Sinclair ZX-80) with 19 keys (A-H, 1-8, NEW GAME, CLEAR, ENTER), but only 11 matrix lines (A-H and 1-8 share lines). A-H are also, respectively, labeled WHITE, BOARD VERIFY, CHESS CLOCK, DISPLAY TIME, STOP CLOCK, SKILL LEVEL, GAME MOVES, and BLACK. The rear plate reads: “Commodore International Limited / Power supply: AC adaptor model C160 / Power rating: AC 10V 600 mA / CHESSmate, 201490 01, made in Hong Kong / CAUTION: DO NOT OPEN MACHINE. UNAUTHORIZED SERVICE VOIDS WARRANTY.” This is printed in English, French and German. On the internal view, the ICs are, from left to right, the 6530 RIOT, the 6332 ROM (next to the empty socket for the option ROM), and the 6504.
The Chessmate was developed by Peter Jennings, the original author of KIM-1 Microchess, under contract to Commodore in 1977. The Chessmate’s hardware is in fact based on the KIM-1, but the ROMs are of course filled with Microchess 1.5, not the KIM’s monitor. This was the same version released for the PET; the empty ROM socket on Martijn’s board was intended primarily for upgrades to the chess program. The keyboard mapping is dissimilar to the KIM as well; some of the ports were actually used for sound, and Commodore made some rearrangements to the unit for ease of manufacture after Peter released the unit to them. While simultaneously released in the USA, UK and West Germany, it was significantly more popular in the latter country than in the others (presumably due to greater interest in chess there). Peter received a royalty for each unit produced, and still owns a first-production Chessmate (sadly non-functional) and the original KIM-1 used to create Microchess and develop the Chessmate’s custom version.
As mentioned, the Chessmate has very different ROMs from the KIM-1, and part of this difference extends to the RIOTs. The 6530 and 6532 RIOT “ROM, I/O and Timer” chips, a series of custom multifunction chips developed by MOS Technology, were designed as integrated-design cost cutters, reducing the chip count on the board as it gave the functionality of several chips and didn’t cost much more to manufacture than a regular ROM. Unfortunately, this has one important consequence: RIOTs are rarely transferable between units, because of differing CS logic between models, differing ROM contents, and some versions use fewer CS lines to get additional I/O lines.
This means that the RIOT you find in your Atari 2600 (yes, VCSes have Commodore-designed chips!) is not swappable with the RIOT you would find in a Chessmate, or in a KIM-1; even the KIM-1 by itself is bad on this point, since it had several revisions alone (my unit is Revision D). Martijn’s Chessmate has a RIOT labeled “6530 024 3279″, meaning produced on the 32nd week of 1979; this is one of the last 6530 RIOT production runs known, unfortunate because the later MOS 6532 RIOT is not pin-compatible with the 6530. The “24″ is also worrisome: this means there are no less than 24 6530 RIOT versions floating around in various units, and to the great despair of anyone wishing to repair a moribund representative of these intriguing units, virtually none of them are compatible with any other.
