Sold off some Windows laptops and parts I had Craigslisted to a guy who does refurb/repair. While there, we got on the subject of old Macs. He said that he had some old Mac laptops in his garage storage. He ended up giving me Powerbook 170, Duo 230 & Powerbook 3400.
All three look in good condition. The PB 170 has loose bezel where the screen screws in at the hinge and it's loose on the back as well. I tried screwing it in, but I think the screw standoff is stripped, as it won't tighten up. The PB 3400 looks like it may have had some upgrades or problems as the torx screw heads for the bottom are stripped. Duo looks really clean though.
Do they work? I don't know. I don't have an adapter for any of them. I met up with modplod for a keyboard/mouse that I forgot to pull out of the big giveaway. He's going to hook me up with one of the old 3400 power supplies from the boxes I gave him. Looks the the PB 3400 and the Duo take the same power supply. The PB 170 has the wonky 7.5v/2A (standard across the whole 1xx line from what I can figure), so I'll need to hunt one of those down.
Up until today, I just had the Umax J710 and was going to make that my special project. I thought I was done with the rest. Apparently the Mac gods weren't finished with me yet.
