It’s the only PowerPC Duo that was ever made, so it’s pretty desirable and interesting.
It’s a 100MHz 603e on a 32-bit data bus with no L2 cache just like the PowerBook 5300 series, so it’s not likely to be the best computing experience.
Enjoy it and be patient with it.
The ImageWriter II and StyleWriter are interesting printers. The latter was Apple’s first inkjet printer and widely seen as a big improvement over the ImageWriter II which it basically superseded in the home market.
The Personal LaserWriter LS on the other hand is not. I used to have one like this but it was a NT model that I later upgraded to an NTR and it was quite a nice - if basic - printer. The LS is a cost reduced version that basically offloads the print processing to the Macintosh it’s connected to and it can’t even take a board upgrade unlike its sister, the SC. In addition, these printers need recapping so you’d likely have to do a bit of work to bring it up to spec. It’s better as a parts donor for an NT/NTR imho.
