This is likely an easy fault to fix. Simply remove the bottom case, move the DVDROM drive, and disconnect the PRAM battery (3-wire connector) from the PMU. Reassemble, and the mac…

I have another power brick at home, so I'll try that. The verbage was "If you can get this running, great. If not no big deal..."

if you need parts, I happen to have a TiBook VGA bottom that I can let go for $50 w/ shipping in the USA. All it's missing is the screen and HDD, but if you want, I can ship it ou…

If it's always on "I'm charging!" amber, then it sounds like something might be really wonky with the PMU. Do you have another TiBook that you can try the battery and/or power cord…

Some nubus cards will not work with recent system software, and some (say, the Rocket accelerators) will not work with a ppc processor. That's all I meant. I have a 2300c with CF,…

Actually I did some more reading and found that there arent any CPU upgrades that go straight into the Nubus slot (correct me if I'm wrong) but into the Cache/PDS slot of Nubus pow…

Maybe a sound or video card (in which case compatibility with version of MacOS and ppc becomes an issue), but nothing else.

I had an instructor bring me a Powerbook G4 that won't power up. I tried resetting the PMU and taking the battery out, as well as re-seating the RAM. The charger light in the back…

Can I put a NuBus processor upgrade in my Dock II for use with my 2300c? Is that even possible?

My two cents on this machine... I get a feeling John Sculley wanted to transition Apple into a one-computer company from the day he took over. When Jobs was ousted there were thre…

Apple did come out with the Apple III and that was not II compatible, the Mac was not realy compatible with the Lisa either (nor the II line). Click to expand... Not that is ma…

The Mark Twain was a last hurrah from the Apple II division to keep the II competitive. Apple stayed with Steve Jobs vision and saw the future in the Mac and didn't care about the …

The Apple II line could have kept going for a while if Apple wanted to support the IIgs at all. Apple did come out with the Apple III and that was not II compatible, the Mac was n…

Except that the Twain came long after the 128k. It is also quite possible that Apple wasn't in the least bit worried about the Twain competing with the Mac. The original IIgs mod…

try booting with only one three point five inch drive connected.

I have a feeling that if it was finished, the specs might have been on par with or even possibly exceeded the specs of the 128K. That could explain why it was canned.

Yea, a HD (even SCSI) makes GS/OS much nicer to run. I have a transwarp GS in one of my IIgs and that speeds things up quite a bit (that machine has the REV C SCSI card and an 8MB …

Was the Mark Twain canned because it might compete with the Mac? I imagine that with an 2 megs of RAM, an 8Mhz processor and a built-in HDD it might actually run GS/OS tolerably...…

Well, that site has been around for more than a decade. Back then the pictures were quite good.

Thanks. Its a shame there aren't better quality pictures available.

http://www.apple2.org should have info on the machine, as well as a few snapshots of the Twain on vacation.

Does anyone have any photos or other information about this machine? I know they never went beyond the prototype stage but it would be fun to see more pictures or information about…

They're quiet? Quieter then a Gigabit G4? Click to expand... Don't know the Gigabit. But at least on the Sawtooth there's a fan you can disconnect with no trouble unless you ad…

No. Just unsuitable for the model. All three Beige G3 machines were specified for 384MB total (max.) of RAM with then-current technology, and the desktop version had also a heigh…

What revision ROM? I think the early Beige G3's didn't support secondary drives at all, also B&W rev 1 had corruption issues on secondary drives. Click to expand... yep…
