Might as well start one of my own "Latest..." topics.

I received in the mail today:

  • A PowerMac 6100/66 (Specs unknown, except it has no hard drive)
  • A Mac IIcx (the floppy drive's bad, the seller told me, and it's missing it's hard drive, but it otherwise looks complete)


And just up the road from the post office, we stopped by the relatively new scrap metal place to drop off some junk. I offhandedly said I'm looking out for old Macs, and the guy who runs the place pointed me to a couple he didn't know what to do with. They are:

  • A Classic (the one with the 8 MHz 68000)
  • A Performa 575 (missing a tab on the L/B door, a chip out of the front bezel, and some sort of blue stuff on top, but it appears to be otherwise complete)
  • The remnants of some sort of other Mac, perhaps some sort of full size desktop style Quadra, Performa or Power Mac?


Anyway, these last two are pretty grungy looking, but I think they're salvageable.

I will post pictures and more detailed specs as I find them out.

- oc it to 90mhz!! then it becomes awesome,

- buy another one of my hard drives for this :) i got one in mine and its awesome. Mac os 8.1/8.6/7.5.5 /7.6 on mine

- buy a hd from me for this too :)

heck you could do 6.0.8/7.0./7.1/7.5.5 /w OT1.3 all on their own partitions :)

I may, but I think I have a suitable drive for it.

Same here, although I might reconsider...

OK, so I've gotten it cleaned up and somewhat deyellowed*.

I plugged it in, and at first, it didn't work right (my Classic II did the same thing, but it was worse), but it came to life after a few tries and booted to System 6.0.7. The display is rather distorted and the brightness is poor, so I think the analog board needs repairs. It has the RAM expansion board, so I can max it out to 4 MB (it has 2 MB currently). It has the stock 40 MB hard drive, which appears to be working okay.

Software includes Microsoft Works 3.0 and HyperCard 2.0.

It apparently had served a rather menial task in it's past life at a car dealership over in Citrus Heights (a suburb of Sacramento, CA), which is probably the only thing unique about this machine.

I'll get a few pictures of it up in awhile.

*I used straight Oxy-Clean in the dishwasher instead of regular detergent. Surprisingly, it actually deyellowed the plastics pretty well (I think I'll call it "RetroBright-lite" :) ).

Not all of the PM6100s will OC to 90 MHz. At least that was the summary of the reports from back in the day. There were newer adn older revisions of the PPC601 chip and that plays a part in how much OC the machine will tolerate.

However, I also suspect that the voltage regulator may play a part. Apple used an adjustable LT1086 and the voltage level is set by the relationship of two resistors. Resistors have tolerances.

I suspect that if you get a PM6100 with the resistors at one end of the tolerance range, your PPC is getting a little higher voltage and the thing overclocks better. Get a PM6100 with the resistors at the other end, and the voltage is lower and it does not OC so well.

But that's just a hypothesis.

Hey, do some forensic investigation on that hard disk and send a ransom note to the dealership, using letters cut out from their local newspaper. They're sure to be hiding something }:)

OK, I get that you're joking, RickNel (you are, right?) but please:

Don't anyone ever do something as appallingly dumb as this.

I think he's joking?

Anyway, no new progress so far. I'll have to send the logic board and maybe the analog board for recapping.

Shortly, I'll tackle the Performa 575 and Power Mac 6100/66.

Stay tuned...

Teach me - what is the best choice of emoticon to make sure nobody on this forum is in doubt that I am joking?

I thought the "evil" emoticon would be enough, but apparently it is possible that I might be sincerely evil. :O

Of course, this being the internet, I could also be a dog. Unless better advised, in future I will stick to the "wink" emoticon, since I don't find any emoticon for "bob head and wag tail" to indicate playfulness.

Still no progress on the P575 or 6100, but yesterday, I got an Apple branded Quantum 1.2 GB SCSI Hard Drive, an Apple branded 6 GB HD, an A9M0106 floppy drive (with data cable hacked off and missing :( ) and an AppleCD 300i Plus.

I know what I'll do with the SCSI hard drive (if it works): I'll either put it in some machine and use it there or put it in an enclosure.

The floppy drive I'll probably use for parts because I already have one which works, but missing some screws (unfortunately the "new" one also is missing a few, but it still has some which my other one lacks). If the drive mechanism works, I'll clean it up and use it in some machine that's lacking a drive.

I don't know what to use the AppleCD drive for yet. Maybe I can use it for installing A/UX on something (that requires that I get an enclosure of some kind, though; it's just a bare internal drive right now). I think I'll put it in the Quadra 950 in place of the generic drive I have in there now.

I also got some PC tower which looks like it's in okay shape, but this isn't a PC forum [:)] ]'> .

The best part? I got it all for $11! [:D] ]'>

How true!
Well I got the drives cleaned up (they were quite dirty), and I'm just plugging them into power to see if they spin up.

Good news is that, despite some horrible whining sounds, the SCSI drive spun right up and the heads did their self check thing, so I assume it's operable.

Same goes for the IDE one.

The AppleCD, however, I'm not sure of. There's a light on the front which comes on and glows amber while it's making some whirring sounds, then it goes green.

The tray seems to open and close normally, and it doesn't complain when a disk is inserted.

However, I don't know if it's reading the disk, because it doesn't spin up and make audible noise (except for a slight clicking sound). I think it's spinning, but I can't tell.

Any advice?

My experience is that it won't spin up and read the disk unless it is connected to a machine (properly).

I would suggest just doing a quick check by setting the SCSI ID manually, opening up a machine you have that works (any SCSI machine will do - LCs are great for this), and connecting the molex/SCSI cable and hit boot.

Be a nice quick test with no fiddling to get it installed properly.

Today I received in the mail a retail copy of Mac OS 8.5 (complete with box and cellophane overwrap!) and an LC network card.

Will the LC card work in an LC III? I don't see why not, but I thought I'd ask anyway.

It's thinking like that which put 150 boxes (no really, I have an inventory, there's 150) in my attic. It's not all Mac stuff. Most of it is or Mac related (electronic parts for repairs or future projects).

Of course, some of the boxes are small -- 10" X 6" X 8" or some such, but many are large. There's a pretty even mix.

Yes, I know. That is why I have a bunch of junk piling up (unlike you, I don't have it inventoried very well).
It should work.
OK, I guess I'll give it a try.

Well, I guess it doesn't matter anymore...
...Because I just got an LC! It comes complete with 12" RGB monitor, keyboard, mouse, and User's Guide.

All for $50 (which probably wouldn't surprise anyone, considering how common they are). I think it needs a new hard drive (and probably new capacitors), but it appears to be in good shape overall with minor yellowing.

I also got a box full of PowerBook G4s for $140 shipped (about $28 shipped each) which I plan on fixing up (I could get at least one going as I think I might have the necessary parts left over from last year's restoration project). I'm going to probably sell most of them when I'm done (though I might keep one for myself because it's the HiRes model).

And coming soon is uniserver's Quadra 840av (I like a challenge every now and then) and possibly a G5 (I know, I know...) if I can get my act together monetarily.

As for the other stuff, I haven't done much with it yet because I've been busy with other stuff.

Well, I got the G5. It's a dual 2.0 GHz model (A1047?). It has an ADC port, if that means anything.

Unfortunately, the rear foot got mangled during shipping, so I bought a new/used case for it from eBay for $50 shipped. Hopefully that will make it as good as new.

I also got TMG's Mac Plus. Aside from a chip in the front bezel (on the top corner) and the usual yellowing, it looks to be in decent shape. I will see about fixing up the analog board and using that to fix up my other one. Then I can *finally* sell mine (I'll probably put it on LEM Swap, since there's a glut of them up here (nothing wrong with that, especially when they're free :) ).)

I also have coming a Quadra 650, PowerBook 150, and PB165c, courtesy of James1095.

Also in the works is (maybe) a Quadra 950 *with* drive bezels! I also have my eye on a floppy bezel and cable on eBay for the Q950 I have now.

OK, so enough about new stuff.

The Mac Classic, while now basically good as new, is still having some weird analog board issues, so I've set it aside until I can get a new one.

The 6100,likewise, has been set aside because I haven't had the time it seems.

The Mac IIcx was merged with my other one (and the remnants went to Trash for his experiments) to hopefully make a working machine. At the very least, it's complete, so that's a start (there's something to fix, in other words :) ).

That's all for now!
