Mega ST

The Mega ST was launched in 1987 by Atari aimed at the professional market. It had a re-designed case consisting of a separate keyboard and CPU unit. It also included a Blitter chip to speed up graphics, and a battery backed clock.

The Mega ST computers were shipped with TOS 1.02 and featured several new features as follows:

• - BLiTTER chip (for faster graphics).
• - Internal expansion bus.
• - Separate keyboard and CPU.
• - Either two or four megabytes of RAM.
• - Peripheral co-processor slot (for 68881 coprocessor, etc.).
• - Battery powered clock.

It was eventually replaced by the upgraded Mega STE.
