Your Mac shows 512K because it has the original 64K ROMs most likely. You actually have 1.5MB of RAM installed, it looks like. The mobo RAM chips have probably been replaced upgrad…

Sounds like typical symptoms of capacitor leakage. My Classic II gave me the jailbars a few years back, washed the board and although the sound never returned, the machine was as g…

I have a classic II that had a similar problem, it was cap leakage.

Hehe I was waiting for someone to see the CD-ROM and go "wtf" Indeed it is by my own hand. On a poor resolution iPhone camera it looks like a decent job, however up close you can …

Methinks the classic II is slightly dead. Pulled the thing apart again, the motherboard was fairly free of dust. Examined the RAM and connectors, no tarnishing or discolouration.…

I have to agree with the consensus that the CD-ROM equipped IIsi is a hack. But one well-executed hack, at least from the outside. When I get my IIsi out of storage, I may have t…

That could be a sign that your power outlet isn't grounded properly. I have two outlets in my house that are grounded "differently" than the rest of the house. If I connect a pie…

"Software for processor cards in PCI power macs is not *required* since it replaces the original processor. It will run just fine, except Apple System Profiler may not display the …

That is weird. None of the Mac fan sites that I can find makes any mention of a IIsi coming with an internal CD ROM or of any upgrades from Apple or third parties to allow that. Yo…

Austin's Goodwill Compter Works is excellent, and there are several other computer recycle / resale operations, as you'd expect in a university town. Click to expand... What ar…

I remember hearing back in the day of people getting OS 8.5 - 9 to work on PPC upgraded Quadras by using a program such as Wish I Were to change the Getstalt ID to that of a simila…

Yep, that machine most certainly does have an internal CD-ROM...likewise I'd be really interested to see a pic of the guts of the machine.

Is it just me or does that IIsi have an internal CD-ROM? If so, how exactly did you go about putting that in?

Well scored there LCGuy! Getting the machine over 512MB will make a big difference in OS X - but it should still run adequately. And they make great DVD players, especially with th…

I hacked the Mom account with brute force. It didn't take very long. The password was "mom". Here is Apple System Profiler. I think I have the PDQ because of the L2 Cache. Un…

Yeah, for the time they were tiny. By today's standards, not so much.

Ah! It's not a real hyperdrive. I opened it up and no hard drive, controller, etc. Just a 512k with a HyperDrive case, for whatever reason. Oh well, it's still cool. One of these d…

I think that some of the RAM might be bad, because the 8100 is now unstable. I'm getting random Finder quits, hangs, and even a System bomb on startup (you know, the fun kind, wher…

Sometimes if you leave it on for a long time (and we're talking anywhere from 30 minutes to 3 hours) it will just "mysteriously" chime and start up. I've done this on an SE/30 and …

ROTFLMAO, I just LOVE your username, dorkbert! :lol:

Actually I have toaster boards just lying around... :}

Success! It turns out that the problem was two-fold: first was the PRAM battery, second was a SCSI conflict. Both are two really newbie mistakes which shouldn't have taken 5 month…

Nope. No green lights inside a stock "Macintosh" or an OEM upgrade. If you have one, there's something undeniably foreign inside there. Can't imagine why there would be one inside …

Look under the monitor bezel on the front for a serial number sticker. The letter after the M0001 number will tell you what model your machine started out as. Click to expand...…

We've got a big trash cleanup coming up here next month. I'm hoping to pick a few more Macs then, though it's getting harder to find the oldest stuff. I've found 3 Pluses out for t…
