PowerBook 100 Update

I replaced the broken 40MB SCSI HDD in the PB100 with an 80MB drive from the busted up 165c. I installed Mac OS 7.1 and it runs quite nicely (I have 4MB of RAM). The screen has a few rows of missing pixels from the left hand side but nothing that inhibits use. One of the feet is broken but I have a second battery and the external floppy drive.
