The year was 1978. Atari was at the top of the video gamming world with its 2600 VCS game console. Atari management looked around and saw a new and potentially lucrative market just beginning to take shape. This market was the Home Computer Market. They saw a market with relatively few major competitors and Atari was in a great position to market a computer of their own. They, after all, were a trusted household name, everyone owned an Atari or knew someone who did!

So December of 1978 Atari introduced the 400 and 800 series computers. The actual computers were not delivered until late 1979 due to production problems. The 400 was a scaled down version of the Atari 800. Introduced as an entry level computer based on the same MOSTEK 6502A processor running at 1.70 MHz with 16K of user RAM built in. It had a membrane style keyboard (not very touch type friendly) with 62 touch sensitive keys and 4 special keys to the right of the keyboard.

It stood out amongst the other computer offerings of the day with its graphics and sound capabilities. It was capable of producing 128 colors on the screen using the CTIA video processor and up to 256 colors with the upgraded GTIA video processor chip used on later versions of the computer. The 400 was first amongst the early computers to be able to display 4 programmable screen objects simultaneously called ‘Player-missiles’ (also known as ‘Sprites’ on Commodore computers). This was at a time when the most computers produced only monochrome displays or very primitive 8 color screens. The graphics were handled by a custom chip called the “ANTIC” (CTIA/GTIA). This chip was designed to work as a sort of co-processor to take the work load away from the main processor to display graphics and color on the screen.

The team that developed the custom chips inside the 400 and 800 was headed by Jay Miner who later, after leaving Atari, headed the teams who developed the custom chips that surrounded the Motorola MC68000 processor that powered arguably the most advanced computer of its time, The Amiga 1000!

TRS-80 was Tandy Corporation’s desktop microcomputer model line, sold through Tandy’s Radio Shack stores in the late 1970s and early 1980s, and one of the earliest mass-produced personal computers. The first units, ordered unseen, were delivered in November 1977, and rolled out to the stores the third week of December.

The line won popularity with hobbyists, home users, and small-businesses. Tandy Corporation’s leading position in what Byte Magazine called the “1977 Trinity” (Apple, Commodore and Tandy) had much to do with Tandy’s retailing the computer through more than 3,000 of its Radio Shack storefronts. Notable features of the original TRS-80 included its full-stroke QWERTY keyboard, small size, its floating point BASIC programming language, an included monitor, and a starting price of $600.

The pre-release price was $500 and a $50 deposit was required, with a money back guarantee at time of delivery. One major drawback of the original system was the massive RF interference it caused in surrounding electronics. Stricter FCC regulations on interference led to the Model I’s replacement by the Model III.

Radio Shack announced the TRS-80 (Tandy Radio Shack) at a New York City press conference on August 3, 1977. It cost $399, or $599 with a 12″ monitor and a Radio Shack tape recorder as datacassette storage. Before this, the most expensive product Radio Shack sold was a $500 stereo.

The company hoped that the new computer would help Radio Shack move into higher-priced products, and improve its “schlocky” image among customers. Small businesses were the primary target market, followed by education, then consumers and hobbyists. Despite its hobbyist customer base, Radio Shack saw hobbyists as “not the mainstream of the business”. Although the press conference did not receive much media attention due to a terrorist bombing elsewhere in the city that day, “six sacks of mail” arrived at company headquarters asking about the computer, and over 15,000 people called Tandy to purchase a TRS-80, paralyzing its switchboard.

Unlike competitor Commodore—which had announced its PET several months earlier but had not yet shipped any—Radio Shack began shipping computers by September. Still forecasting 3,000 sales a year, the company sold over 10,000 TRS-80s Model Is in its first one and a half months of sales, and over 200,000 during the product’s lifetime.

Turbo Chameleon 64 is an extremely user-friendly cartridge that can be used without opening the computer. It is just plugged to the expansion port of the C64.

The Turbo Chameleon 64 cartridge can also be operated as a stand-alone unit (since it’s basically an FPGA computer like the C-One or the Minimig in a C64 cartridge case), replacing the computer, the floppy drive and the heavy power supply.

When used as a stand-alone unit, a USB power adapter or active USB hub can be used as a power source.

Changelog:

• New VGA controller with new modes and VIC-II sync.
• Tripple buffering mode added for properly displaying IFLI pictures.
• Scale-2x video scaling algorithm added.
• Scanline emulation added.
• In cartridge mode real CIAs registers and interrupts are used (allows use of a modem).
• In cartridge mode real VIC-II registers and interrupts are used (allows use of a lightpen).
• Fixed I/O assignments for FPGA (lower power use).
• Lowlevel SD-card functions now use multiple block reads if possible, which increases linear reading speed by about 40 to 50% (most noticeable on large files, such as REU images)
• BUGFIX: fixed error handling and timeouts of the IEC routines, which makes all related operations more robust.
• BUGFIX: added missing timeouts to SD-card functions.
• Joystick port 1 now also works for navigating the menus.
• BUGFIX: on some C64s pressing shift would result in phantom keypresses (F1/F2) under some conditions.
• NEW: various new VGA modes and other options for the new VGA controller (see manual)
• Improved loading speed of file inside T64 images.
• Improved keyboard handling to make the browser a bit snappier.
• BUGFIX: the size of the character ROM saved by the ROM saver was incorrect.
• BUGFIX: .wav player stops at the end of the file and does not continue playing garbage.
• BUGFIX: files bigger than 2k are displayed correctly by the .txt viewer.
• BUGFIX: when copying files out of a t64 image the resulting file was missing the last two bytes and/or the last block was missing completely.
• BUGFIX: filecopy from/to a IEC device did incorrectly abort after 1 block.
• BUGFIX: filecopy filename character set conversion was broken.
• BUGFIX: AR/RR ROM was not correctly disabled when autostarting programs from the filebrowser with AR/RR enabled as default cartridge.
• NEW: added DOS wedge command (see manual)
• NEW: added load and save commands (see manual)

from Wikipedia:

The Atari ST is a home computer released by Atari Corporation in June 1985. It was commercially available from that summer into the early 1990s. The “ST” officially stands for “Sixteen/Thirty-two”,[2] which referred to the Motorola 68000′s 16-bit external bus and 32-bit internals. Due to its graphical user inferface, it was known as the “Jackintosh”, a reference to Jack Tramiel.

The Atari ST was part of the 16/32 bit generation of home computers, based on the Motorola 68000 CPU noted for 128 kB of RAM or more, a graphical user interface, and 3½” microfloppy disks as storage. It was similar to the Apple Macintosh and its simple design allowed the ST to precede the Commodore Amiga’s commercial release by almost two months. The Atari ST was also the first personal computer to come with a bit-mapped color GUI, using a version of Digital Research’s GEM released that February.

The ST was primarily a competitor to the Apple Macintosh and the Commodore Amiga systems. Where the Amiga had a graphics accelerator and wavetable synthesis, the ST had a simple frame buffer and a 3 voice synthesizer chip but with a CPU faster clocked, and had a high-resolution monochrome display mode, ideal for business and CAD. In some markets, particularly Germany, the machine gained a strong foothold as a small business machine for CAD and Desktop publishing work. The Atari ST also enjoyed some market popularity in Canada.

The ST was also the first home computer with integrated MIDI support. Thanks to its built-in MIDI, it enjoyed success for running music-sequencer software and as a controller of musical instruments among amateurs and professionals alike, being used in concert by bands and performers such as Jean Michel Jarre, Madonna, Eurythmics, Tangerine Dream, Fatboy Slim, and 1990s UK dance act 808 State, as well as naming German digital hardcore band Atari Teenage Riot.

The ST was later superseded by the Atari STE, Atari TT, Atari MEGA STE and Falcon computers.

In late 1989, Atari released the 520STE and 1040STE (also written STE), enhanced version of the ST with improvements to the multimedia hardware and operating system. It featured an increased color palette of 4096 colors from the ST’s 512 (though the maximum displayable palette of these without programming tricks was still limited to 16 in the lowest 320×200 resolution, and even fewer in higher resolutions), Genlock support, and a graphics co-processor chip called Blitter, which could quickly move large blocks of data (most particularly, graphics sprites) around in RAM. It also included a new 2-channels digital sound chip that could play 8-bit stereo samples in hardware at up to 50 kHz.

Two enhanced joystick ports (EJP) were added (two normal joysticks could be plugged into each port with an adaptor), with the new connectors placed in more easily-accessed locations on the side of the case. The enhanced joystick ports were re-used in Atari’s Jaguar console, and are compatible. RAM was now much more simply upgradable via SIMMs. Despite all of this, it still ran at 8 MHz.

The PETdisk is a new storage device, made by bitfixer, for the Commodore CBM / PET with an IEEE-488 port.

The system is in two parts. A datassette module that makes it possible to play “data” from a PC soundcard to the CBM / PET and play “data” from the CBM / PET to the PC. The IEEE-488 module has an SD card and a micro processor.

You can use the commands LOAD, SAVE and LOAD “$” to load or store data on the SD card. The device number can be changed with a help of a jumper. The USB cable is used to provide 5VDC from the datassette module to the IEEE-488 module.

The Commodore PET 2001-N (the N was short for “New”) is a successor to the Commodore PET 2001, it has a bigger keyboard and 32KB dynamic RAM memory. The larger keyboard means that the first cassette drive now has to be an external unit.

from Wikipedia:

The Commodore PET (Personal Electronic Transactor) was a home/personal computer produced from 1977 by Commodore International. A top-seller in the Canadian and United States educational markets, it was Commodore’s first full-featured computer, and formed the basis for their entire 8-bit product line.

The PET 2001 was announced at the Winter CES in January 1977 and the first 100 units were shipped later that year in October. However, the PET was back-ordered for months and to ease deliveries, early in 1978 Commodore decided to cancel the 4 kB version (also because the user would be left with barely 3 kB of RAM).

Although the machine was fairly successful, there were frequent complaints about the tiny calculator-like keyboard, often referred to as a “chiclet keyboard” because the keys resembled the gum candy. The key tops also tended to rub off easily. Reliability was fairly poor, although that was not atypical of many early microcomputers. Because of the poor keyboard on the PET, external replacement ones quickly appeared.

In 1979, Commodore replaced the original PET 2001 with an improved model known as the 2001-N (the N was short for “New”). The new machine used a standard green-phosphor monitor in place of the light blue in the original 2001. It now had a conventional, full-sized keyboard and no longer sported the built-in cassette recorder. The kernel ROM was upgraded to add support for Commodore’s newly-introduced disk drive line. It was offered in 8kB, 16kB, or 32kB models as the 2001-N8, 2001-N16, and 2001-N32 (the 8kB models were dropped soon after introduction). Finally, Commodore added a machine-language monitor to the kernel ROM that could be accessed by jumping to any memory location with a BRK instruction. It did not include a built-in assembler and required the user to enter hexadecimal numbers for coding.

Sales of the newer machines were strong, and Commodore then introduced the models to Europe. The result was the CBM 3000 series (‘CBM’ standing for Commodore Business Machines), which included the 3008, 3016 and 3032 models. Like the 2001-N-8, the 3008 was quickly dropped. The change to CBM occurred because of a trademark dispute with Philips over the PET name.

CBM prg Studio Version 2.5.0 is released. There are a lot of new features in this version. I’d really appreciate it if you report any bugs you find or have any suggestions/comments.

CBM prg Studio allows you to type a BASIC or Machine Code program in using a nice Windows environment and convert it to a ‘.prg’ file which you can run on an emulator, or even a real C64 / VIC20 or PET if you’re feeling brave and have the right kit.

CBM prg Studio is the result of merging C64PrgGen and VIC20PrgGen. Adding new features and fixing bugs in two apps which were 95% similar was a bit of a nightmare so merging them made sense.

It was also a good opportunity for a face lift and to add some new features, such as:

• Programs are project based, meaning all related source files, sprite files etc. are kept in one place and multiple source files can be linked more easily.
• Tabbed MDI.
• Syntax highlighting.

What CBM prg Studio isn’t is a front-end for tok64, cbmcnvrt, bastext or any other tokeniser / detokeniser / assembler. It’s all been written completely from scratch.

New features:

• Some of the IDE’s colours can be changed (background, tab strip, selected and non-selected windows).
• Menu to control open windows.
• Warnings if invalid BASIC jump (goto, gosub etc.) destinations are detected.
• ZPOpt directive added.

Bugs fixed:

• Added ‘missing’ colours to VIC 20′s screen designer.
• Default project location not being saved if the target machine was not changed.
• Assembler not assembling mixed case text directive strings properly.
• Dark and light gray colours were switched.
• Opening a project after a project had already been opened would use ‘my documents’ rather than the project directory.
• Incbin failed when used screen designer files.
• No colours were visible when starting the screen designer without loading a previous file.
• CTRL+Z not scrolling to changed text.
• * not recognised for current address.
• Local labels not recognised in certain circumstances.
• Generation/import of prgs > 65k for C128 programs would fail.
• Missing BASIC 7 ‘RLUM’ keyword.
