I got 16 Macs today, all free:

7x Macintosh IIsi

6 with ethernet cards

1 with fancy NuBus "Macintosh Display Card"

1x MACINTOSH QUADRA 700

OH MAN I wanted one of these for so long!!

Very good condition, feet intact.

I put the video card from the IIsi in it. I have a much nicer Radius card somewhere I might use instead.

1x Performa 630CD

4x Macintosh LC

1x Macintosh LC III

1x Macintosh IIci

1x Macintosh LC 520

This works fine but is badly yellowed.

I guess I have to update my signature!

[edit]

I forgot, I got 2 of those SCSI Apple External Hard Drives (the ones that have the Apple logo but are made by LaCie) and also an external SCSI CD-ROM (non-Apple). Also a few keyboards, mice, and tons of cables.

Fantastic haul!

The IIsi Nubus cards, the Q700, and the Apple/LaCie HDs are in my view the real gems here.

Wow, that's a great haul!

That Nubus video card is pretty cool; it gets thousands of colors at 640x480. Perfect for an AppleColor High-Res RGB Monitor. It's also full-length which is quite exquisite. I have a Radius Thunder/24 card that I'd like to use in the Quadra 700, though. That card came hidden inside a Power Mac 7100 and currently resides in my Quadra 650 which is, well, around somewhere. (I have 71 Macs, so they're not always easy to dig some particular one out.)

You can see a list and pictures of my Macs here if you're interested:

Update: I have purchased Narion's Mac TV case in the trading post. So the LC 520 will be turning into a REAL Mac TV! He has graciously included a Mac TV logic board in the deal, so this will indeed be the real thing.

I will DEFINITELY be posting pictures of that process!

man i would love to get ahold of a external scsi HDD

Turns out the Quadra 700 has A/UX installed!! Very cool.

They all work more or less. One LC won't boot. I get the question mark, so it either needs to be reinstalled or at worst a new HD.

One IIsi has a problem that it will shut off immediately after being turned on. Disconnecting the HD power cable and ethernet Nubus card prevents the problem. Either the HD, ethernet Nubus card or the PSU is bad in that one. (More testing/swapping is required to narrow it down.)

Update:

The LC started working all on its own after I restarted it a few times. I'm not sure exactly what the problem was. Several of the Macs I got had hard drive stiction, (drive would not spin) but the old "take it out, twist it back and forth really fast" trick worked like a charm on all of them. I believe these computers have not been turned on in at least 10 years so the grease in the bearings probably just congealed over time. After breaking them free with my little trick, they all seem to be just fine.

The IIsi has something wrong with the power supply. Holding down the power button results in the on-off-on-off-on-off effect. It works fine when a known-good power supply is swapped in. I'm not really sure where to start with that, maybe I can just use this one for parts since I have so many.

I have finished cleaning all of them and removing all the non-Apple stickers. Unfortunately some stickers left some fairly noticeable tan lines.

I think suspecting the electrolytics is a good bet. Recently I've been overhauling a Personal LaserWriter LS power supply containing 1992 date code original parts. Of the first five electrolytics that I have examined then replaced, ALL FIVE were leaking liquid electrolyte (I checked that it was not flux residue). The power supply would not start up but changing these resolved the startup problem. I'm talking about conventional radial lead electrolytics, not those pesky surface mount parts that we already know are troublesome when old.

The leaks were appreciable. I found them by reaching in and wiping the noses of the caps with a clean bent piece of bare wire then inspecting the wire for picked up sticky liquid. These particular caps were spaced above the board so it was easy to probe their lead seal areas.

Electrolytics have long been a necessary evil in electronics. I'm seeing evidence that 1992 electrolytics of conventional construction may be reaching end of life. I'm going to replace all of the remaining ones in the supply that I am overhauling. The larger ones may have much more electrolyte to spare, but they also have to withstand very high ripple current heating from the motor drives in my printer. I also do not like what electrolyte can do to PC boards if left there long enough. [!] !]'>

Edited post: Important switching power supply safety note: The physically largest volume capacitor usually is the one that is charged from a bridge rectifier connected to the power line voltage, and stores a potentially lethal amount of charge even after the line is disconnected. There's usually a bleeder resistor path to discharge it over a minute or so, but designs vary and bleeders can fail. The catch 22 is that the topside of the PC board offers few clues as to test points to measure and if necessary discharge this capacitor before unmounting the PC board. So any probing for leaks, and unmounting the PC board from the enclosure, must be done with caution and appropriate insulation. Keep in mind that any of the caps may have some remaining charge.

I don't suppose you would consider selling one of the IIsi's? My beloved IIsi is having issues with disk access because the drive controller chip legs are corroded. I have had a lot of trouble finding clean, rust/grime free working replacement boards for it. PM me if you're interested.
