Launched in the first wave of Duo machines, along with the Duo 210, the Duo 230 offered users the same ultra-compact machine, but with more bang for their buck.

History

The PowerBook 1xx series had shown that Apple could produce a portable Macintosh that truly was portable. In one slimline box users had everything they needed...or so it seemed at first. Despite being a fraction of the size and weight of the Macintosh Portable, the PowerBook 1xx machines were still relatively bulky and didn't appeal to all users. The need for an even more portable Macintosh had arisen and the solution came in the shape of the new Duo series.

The Duo machines were identified not for what they included but for what they excluded. By eliminating features such as the floppy drive and a multitude of sockets, the Duo shrank from being nearly 6 lbs to just 4.2 lbs – a big saving, provided you were prepared to make the appropriate sacrifices.

With a decent 9.8" screen – albeit of the passive matrix variety, complete with the usual 'ghosting' and 'streaking' issues – an improved memory ceiling (up from 14 MiB to 24 MiB), an ultra-thin case and a very respectable battery life, the Duo machines were ideal to be thrown into a bag and taken on the road for the day. Back home, users could simply plug the machine into one of a multitude of docking station options and access their external drives, network connections, and everything else that non-Duo Mac users were using.

Under the hood, the Duos ran at a decent speed, too; and while the Duo 210 was clocked at a very respectable 25 MHz, the more powerful 230 was boosted to an impressive 33 MHz. For $360 dollars over the price of the 210, users may have expected a little more than just 8 MHz of extra speed, yet that was all they got as, speed aside, the two machines were identical.
