The Atari Mega ST was the "professionnal" version of the Atari STf.

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 and by the TT.

Please consider donating your old computer / videogame system to or one of our partners from anywhere in the world (Europe, America, Asia, etc.).


So many terrific memories!

I had a Mega 2 system while living in Fairbanks, Alaska, with a Spectre GCR. The unfortunate fact about a few of these machines (mine was one of ''em) is that they had a couple of TTL ICs on the motherboard which didn''t provide enough power for some of the memory chips with the Spectre attached.

It crashed using the device quite often, but otherwise I have many fond memories from this particular model. My outfit had a 44 MB cartridge drive and the standard color monitor.

I still miss my ST...
