The SX212 modem was one of the rare Atari peripherals that could be used with all the Atari computers range, from the 400/800 series up to the Falcon. It had both the Atari I/O ports for the 8-bit systems and a standard RS-232 connector for ST's
|
||
|
||
It was a 300/1200 baud modem compatible with the well-known Hayes 'AT' commands.\
|
||
Cable and software was sold separately, depending of the computer used.

|
||
The SLM-804 was actually a Kyocera F1000 printer but without neither on-board processor and memory nor buttons other than the on/off switch. It was first delivered with the Mega ST but could be connected on all of the ST series computers through a dedicated interface box.\
|
||
The printer used the processing power and the RAM memory of the ST computer for printing at 8 pages per minute and 300 DPI. The paper tray held 250 sheets.
|
||
|
||
Thanks to **Francois Michaud** who donated us this printer.

The Atari Mega ST was the "professionnal" version of the [Atari STf](/museum/atari-520-1040-stf-stfm/).
|
||
|
||
Atari added the "Blitter", a custom chip designed to perform quick memory moves and increase display speed. The Mega ST had a small battery to hold time and date and a small fan (except for the Mega ST1).
|
||
|
||
This computer was especially designed to be the cheapest publishing solution (and it was!). The photo shows the Mega ST 4 (4 MB) with a monochrome display (640 x 400), the publishing software "Publishing Partner", the Atari SH 205 hard disk (an old 20 MB 5.25" MFM hard disk) and the Atari SLM 804 laser printer. This printer was really cheap because it had no on-board memory and no page description language, the page was created in the Mega ST memory, then sent to the printer.
|
||
|
||
The Mega ST had a pretty good success and was replaced by the [Mega STe](/museum/atari-mega-ste/) and by the [TT](/museum/atari-tt-030/).
