Sorry I had to delay this. I needed to dig out certain facts before moving on to this set.
There are three working computers for sale. One is a PowerBook 180. It starts and runs fine. No missing pixels. B&W screen, of course. The working battery (rechargeable) died and was recycled a long time ago, so it runs on a power supply plugged into 120 v. ... a "wall wart". This comes with three "wall warts". One is new and still in the original box. Two have been used. As with many of these, the door on the back (covering places to plus in accessories) broke off a long time ago. I have it, but don't see a way of putting it back on. I've used this PB180 quite a lot. It's been a pleasure. Another is a PowerBook 520. It starts and runs fine, with no missing pixels. Screen is B&W, not color (not a 520c). As with the PB180, the rechargeable battery (Metal Hydride) died and went to be recycled. So it, too, runs on a "wall wart". I have two "wall warts" for this computer. They are not the same as the ones for the PB180. The PB520 is in its original packaging, with all accessories. It has been used very little so it's just like factory-new. I bought this in a moment of passion while working in Calif. at a Mac store and had buyers regret soon thereafter. Reason? I really didn't need it and was "hooked" on the PB180. I've suffered guilt pangs ever since. Fortunately I was working as a consultant (contractor) so I could write it off as a business expense. It's a good computer, neglected, and needs a home where it will be used and appreciated. The third computer is one that I gave to my grandson and he gave it back to me when his parents gave him a much faster box for his birthday. He's a gamer. It's a tower... a Quadra 800/Power PC 601. That's the label that's on it as it came from the factory. I originally bought it from a friend. I've used it in my office, but it's been in storage for several years. It has one PRAM cell; I put a new one in it last week and it started and runs just fine. Now, what is a Quadra 800/Power PC 601 anyhow? You may not be able to find this on the internet or anywhere else. My understanding of it is this. This computer was born about the time the 601 chip became available. Many people had software written for quadra chips. So... somebody at Apple came up with the idea of putting both chips in this box. (As I said, this is my understanding of it. Correct me if you have insight I don't have.) There's software in there that lets the user easily switch between "quadra" and 601. Of course you have to turn it off and let it reboot after making the change. I have the manual that came with it. It's for a Quadra 800, and doesn't mention the 601 chip. One more time... this is my understanding of how this dual capability came about. I like this computer, but have one problem with it. Don't laugh, but the several old Macs I still use (Mac IIsi) are using the 6.0.8 OS. Go ahead an laugh and get it over with. The Quadra/601 won't live with anything less than OS 7.6 or something like that. I have a lot of software that won't tolerate OS 7.0 or higher. I hate to part with this one, but can't afford to re-write all my software (math, statistical) and move into the new century. (I write all of my own code.) This computer is loaded with extensions and games. Teenage grandsons are like that. I suspect that's why at startup it gets off to a slow start. I haven't had the nerve to do a major housecleaning, so it comes with games. There may be yet another computer (a IIx) yet to come. As it stands it will not start up. I have some thoughts on why, and will swap some of those components (notably the PS) and see if that does the trick. The internal HD was a challenge when I last used it. It was suffering from "stiction" (bearings "sticking" and/or friction.) I'll try one of those extra (for sale) internal HDs with this one. OK, so the current lineup is... PB 180 $40 plus shipping expenses PB 520 $50 plus shipping expenses Quadra 800/Power PC 601 $60 plus shipping expenses. Regarding shipping, when shipping computers and other breakable devices my experience with UPS has been this. Once you declare "it's a computer" their eyebrows come up and out comes the box cutter. They open it up and inspect the packaging. They are seldom satisfied. (Actually never, in my experience.) So I would like to take these to an "UPS Store" and let them do the packaging. It costs more, but it's almost a requirement with UPS and breakable things. As before, payment by Money Orders preferred.
