The Atari 520ST was introduced at the Winter CES in January of 1985, 6 months before the Commodore Amiga. Atari did take some shortcuts, though, as the Operating System did not yet exist in ROM, and had to be loaded from floppy-disk when powered on (but then again, so did the Amiga). The 520ST also had no internal floppy drive, but later versions included it.

Bundled with an external 360K single sided 3.5 inch floppy drive, mouse and monochrome monitor, it costs $799. Both Amiga and 520ST are based on the Motorola 68000 CPU, which has a 16-bit external bus, and 32-bit internal, thus the 520′ST’ means ‘sixteen / thirty two’. The Operating System is ‘TOS’, or ‘Tramiel Operating System’.

The 520ST (and Amiga) have a graphical operating system, or GUI, similar to the Apple Macintosh, which was released one year earlier. The 520ST utilized Digital Research’s GEM GUI, although it is not nearly as nice as the Macintosh or Amiga.

One thing that IS very nice is the built-in VT52 emulation. The 520ST can act as a dumb terminal, communicating through its serial port to another system. There was a huge rivalry between Amiga and Atari users, each positive that their computer system was superior, or at least hoping it was.

In addition to the 520ST, Atari release the 1040ST, with built-in floppy drive, and 1Meg of RAM (the 520ST has 512K). Four years later in 1989, the portable ST computer appeared, the Stacy.

The KC 85 (‘KC’ meaning “Kleincomputer”, or “small computer”) were models of microcomputers built in East Germany, first in 1984 by Robotron (the KC 85/1) and later by VEB Mikroelektronik “Wilhelm Pieck” Mühlhausen (KC 85/2, KC 85/3 and KC 85/4).

Due to huge demand by industrial, educational as well as military institutions, KC 85 systems were virtually unavailable for sale to smaller customers. They were based on the U880 CPU (an East German clone of the Z80), with clock speeds of 1.75 and 2 MHz.

There were two main lines in the KC 85 series, the KC 85/2 (project name HC 900) to /4 and the KC 85/1 (project name Z 9001) by Robotron, which was a different system (only the CPU and the name were the same, but later the format of saving the programs on tape cassettes and the BASIC were also made compatible). In 1989, VEB Mikroelektronik Mühlhausen came up with the KC compact, but due to the GDR collapse very few units got actually produced and sold and — being a CPC clone — it was a KC in name only; thus it is usually not counted among the KC family.

The Megafile series (produced by Atari) is based on RLL (MFM) Hard Disk, the MFM technology today has become obsolete.

The system includes the Hard Disk (Seagate ST-157R), controller RLL (MFM) 32D5321 and the power supply. The Megafile was connected to the host through the door ACSI, ACSI is Atari’s proprietary hard drive connector. It is similar to SCSI which was standardized later, but not directly compatible.

The other door instead allows you to connect other devices (eg. other Megafile).

The Atari SM-124 is a high-resolution monochrome monitor designed to be used with the ST series of computers. It is capable of 640×400 resolution at 72Hz in black and white and has a very sharp picture, though the actual viewing area onscreen is quite small, a large black border of about .5 inches or more surrounding the entire screen.

For serious work on the ST, including MIDI sequencing, telecomunications, word processing, etc. the SM-124 is a much nicer monitor than it’s color counterpart

The Mega ST was Atari’s first major enhancement to the ST line of computers. With 1MB or 4MB memory (expandable with add-on cards), built in BLITTER graphics chip, and MegaBUS expansion Slot all packaged into a nice clean pizza-box case the ST line of computers received a boost in power, expandability and professional looks.

Atari was moving forward in the right direction. Also introduced along with the Mega ST line was Atari’s direction into the desktop publishing field.

Atari introduced the SLM804 Laser Printer which attached to the Atari DMA interface port and also the desktop publishing package. Also introduced was the Atari Megafile hard drive system to add stackable harddrive modules onto the Mega ST.

This is the program QL Toolkit for the Sinclair QL home computer written by Tony Tebby (the author of the QDOS and SMSQ/e operating systems) and published by Sinclair on their Silver Label.

QL Toolkit offered a lot of facilities which Tony had originally devised for the original QL QDOS operating system, but which were never released.  It included commands to control jobs, improvements to SAVE and COPY commands, wildcard file handling, and much more.

It also contains a host of example SuperBASIC programs on the microdrive cartridges. It was later to become Toolkit II (or Super Toolkit) which was recognised as the standard toolkit upgrade to the Sinclair QL Home Computer.

This printer was surely an inexpensive ploy on consumers. Out of the box, you got a slow dot-matrix printer that did not have true decenders, and did not have the standard tractor-feed mechanism for using the printer paper of its day.

For an additional price, you could get: a ROM with true-decenders and the tractor-feed mechanism.

The Prodest PC-128 was a rebadged and slightly redesigned version of the French Thomson MO6, apart from case design touching up, technical features was the same as the MO6.

The Prodest PC-128 has two versions of BASIC on ROM both made by Microsoft. Almost all memory (101 KB) was accessible with BASIC thanks to a transparent 16 KB bank switching mechanism. An optional 3.5″ floppy disk drive (640 KB) was available. This machine seems having been sold in very small quantity in Italy.

The MPS 1270 was the first ink jet printer Commodore released, as part of its MPS series. The MPS 1270A had both a Centronics port and a serial bus port. This allowed it to be used by a Commodore computer ( C64 , C128 , etc.) as well as a PC or Amiga.

Note:

• HP 51604A Ink Cartridge are compatible with this printer.
• The power connector have the TIP Negative and the outer Positive (9v 1A)

The 1541 Ultimate-II is a peripheral developed for the Commodore 64 (C64) by Gideon Zweijtzer.

It’s a C64 compatible cartridge that carries an Action Replay, The Final Cartridge III, Super Snapshot, Retro Replay or TurboAss with Codenet support (whatever the user prefers) and a fully compatible FPGA-emulated Commodore 1541 floppy drive that is fed from a built-in Mini SD card slot with C64-compatible files (e.g. .D64 diskimages or .PRG single program files).

The difference between 1541 Ultimate-II and other SD-based & .D64 mounting cartridges (like the MMC64, Super Snapshot 2007, or MMC Replay, SD2IEC) is that the 6502 microprocessor that powers the 1541 floppy and the 1541′s mechanical behavior (even sound) is fully emulated, making it theoretically compatible with almost anything.

File selection and management is done via a third button on the cartridge that brings up a new menu on screen.

Note: This is my first printer.

from c64-wiki.com:

The Commodore MPS 801 was a Matrix-Printer (Stylus-Printer) from Commodore released in the year 1984. MPS stands for Matrix Printer System, an invention from Commodore.

The Commodore MPS-801 was one of the first Printers offered by Commodore for its home computers. The printer used fan-fold paper via a paper tractor. The print resolution was a 6×7 Matrix at 10 chars/inch. The printing speed was about 50 chars per second.

Because of its 7-pin print head, character descenders couldn’t be created with the MPS 801. This was later made possible through some software tricks. The printer only supports unidirectional printing (i.e. it is only printing when the print head moves from left to right). On the way back to the left, the print head was inactive, which made the printer very slow, compared to later models. The interface to the computer was a serial IEEE-488, the serial bus for the C64.

The printer was not developed and produced by Commodore. The MPS-801 was produced by the Japanese company Seikosha, a subsidiary of the clock manufacturer Seiko (the same model there was named Seikosha GP 500 VC). At that time, Seikosha was one of the largest printer manufacturers in the world and was also manufacturing printers for Atari, such as the Atari 1029 printer.

Apart from the complete ASCII-charset the 801 could also print all Commodore graphic characters and reverse characters were possible. In addition to text and special glyphs the printer was capable of printing graphics.

For manual paper-handling there was a mechanical handwheel on the right side of the printer. Additionally a membrane key was provided for incremental linefeed.

Two Commodore 64 added to my collection. The external case was bit dirty, it took me a couple of hours for a good cleaning but now the two C64 are like new.
