The Wallaby laptop was introduced in 1989 and was significantly lighter, at just over 4 kg, and easier to carry than Apple's own Macintosh Portable released at around the same time.
The Wallaby featured a built-in pointing device located below the keyboard, named the Trackbar (with earlier models referring to it under the trademark of Isopoint); it was a cylinder that scrolled up and down and slid left and right.
The Notebook ran on the same style of lead-acid camcorder batteries as the earlier Laptop, and had a 9.7" passive-matrix monochrome LCD display.
This permitted easy RAM installation and optional upgrades; the daughtercard could simply be swapped out for another one with a faster CPU, or an FPU inserted into the available socket.
