Yea. It is a good PB of its era. It will run OS 7.6.1 gracefully at 33MHz, if you maximize its RAM. And therein lies the rub. The base RAM is 4MB. These days, to find a 10MB RAM expansion card has just a little more probability than winning a State lottery. 4, 6 and 8MB cards also exist. It can support an augmented System 7.1 (a hybrid retrofitted with choice System 7.5 bits on top of 7.1 Pro, making a sort of 7.1.3) also if RAM is lacking. Its monochrome (but limited to 16 greyscale) active-matrix display is better than the passive-matrix display of its sibling PB 160, but some displays suffer from the (incurable) tunnel-vision, a progressive darkening of the corners until the blackness meets in the middle. Has a 68882 FPU, which the 160 does not.

Most of its parts are interchangeable with the 160 (25MHz), but not the inverter because of the difference in voltage for active- and passive-matrices. Good keyboard. Lumpish AC adapter. A trackball that is more responsive than a trackpad, if you like trackballs at all, and if both of its X and Y axes are still working.

Easily re-celled batteries (NiCd), with no 'smart' circuitry inside, but the case does not come apart gracefully because it is welded.

May you enjoy it!
