PB150 w/ Adapter. Unfortunately the battery has leaked, the trackball collar's tabs are broken, and no response can be had from it.
PB145 has old screen syndrome. For about three minutes the brightness goes between normal and non-visible, with no discernable reason. After that it settles down and is quite usable, with 7.5.X installed. The floppy drive is bad -- it won't recognize disks and the eject mechanism doesn't work. Dead Battery.
PB170. Has no system installed, but otherwise seems to be the most pristine of the lot good screen display of ?-disk, and everything else seems to be in working order (except dead battery, of course) A note attached said the disk drive might not work. Since I don't have a bootable disk to test with, I cannot attest to this. I'll have to get a mac with a disk drive on the net to get apple's online systems.
One adapter between the latter two. I'd bet a bunch of cleaning would solve many of these problems.
Any interest? I'm open to trades. Hopefully near NYC
