Using a CF->USB Adapter you can format the CF under OSX or OS9 on a Desktop. And with a CF->PCMCIA Adapter, you can use any Powerbook with a PCMCIA Slot to format the CF as well. In fact, this is the better option.

Using a 190/5300/1400 running 7.6.1 with the CF in the PCMCIA slot, you can partition the CF into slices of 1.7GB or less and then format them according. Then add the system to the CF's first partition, and bless the folder.

System 6.x - 8.0 only recognizes HSF format and that uses partitions smaller than 2GB in size. Many prefer 1.7GB when using large hard drives.

You have PC Exchange for the SE\30 or SE? This would allow you to have PC Windows and OSX file exchange through floppy. If you save the files in .doc format in Word 5, you should be able to read/write them in Word 2011. If not, you need to downgrade to Word 2008.

The PB150 needs a logic board and LCD recap. You can ask around the forum for those who can do it for details and maybe doing it for you if you cant (Uniserver, PintoDave, Ferrix97)
