Apple CD SC . . .

[Trash80toHP_Mini]

. . . evisceration. 8)

My DOA CD SC is just about ready to rise from the ashes in a Phoenix-like conversion into an, Intel Inside, Dual Core (Snow White design language correct) ATOMicMacMiniNetTop™ . . .

. . . and I was asked about the innards of my KeyStone, so I took the first set of shots of the CD SC, to document the sheet metal chassis, before surgery commences.

The CD Drive chassis above, will be the very first piece to be modified for MoBo Clearance.

But I'll put everything back together to get some shots of the complete interior and exterior . . .

. . . or not! }

Do you have your shopping list ready already, JT?

Atom should be easy going, but one of the newer AMD APUs may be interesting too.

Unfortunately those seem to want 65W or so. My A640 Macmini even wants 95W.

Dual Core ATOM MoBo - gots

8GB Mini PCIe SSD - gots

USB 2-Bluetooth 2 dongle for tethering to 'Droid - gots

200W ATX Mini PSU - gots

Source for even smaller 250W ITX/ATX Mini PSU as used in IIsi PSU Hack - gots

2GB SDRAM(?) - gots

Now if I could just get the bloody ubuntu install CD to work without requiring an active internet connection . . .

ubuntu used to be soooo easy! :

Got the USB 2-Bluetooth 2 Dongle in Friday's mail, that ought to be easier to get to work than the crossover cable to the grlf's router or using the USB Cable for the 'Droid . . .

. . . or not. :-/

Edit: I've got a bunch of inter-related threads abut this different aspects of this hack, so I'll be doing a new thread in hacks to cover it, with linkage in the opening post to those threads and this one.

I'll be copying your post, my reply and any others into that hack specific thread after I get it set up. [] ]'>

IOW, I'll clean this one up so it's a straight up Peripheral Teardown kinda deal.

JT - I had no luck, whenever I tried something with Ubuntu.

(Ubuntu users, just disregard this - problem was certainly on my side)

GParted Live is the one for me, runs almost everywhere, with or without ethernet.

For a full install I still like the old Mandriva2010 release, because all my Eee 1001HA´s devices were supported oob.

Off topic: As a kind of lazy CLI hater, I appreciated SheepShaver, BasiliskII and a lot more being included in Mandriva´s repository too.

No need to tinker with those dreadful compatreadline libraries and other dependencies, usually to be taken care of with GNU.

Setting up Snow Leo, I would try http://www.osx86.net/downloads.php?do=file&id=1070 with a retail DVD

or Nawcom´s USB version http://www.osx86.net/downloads.php?do=file&id=2015 if you have a running OSX already.

A Lion kernel for Atoms is availabe too: http://www.osx86.net/downloads.php?do=file&id=1796

I did not try myself, cause I dont feel a real need for 10.7.

 

[Trash80toHP_Mini]

I don't have any real need for anything but ubuntu, ATM. The re-mix has been running flawlessly on HP-Mini since my run-in with inadequate restore utilities for the WinHome3/whatever that died a fittingly miserable, agonizing death. It would have required a trip to HP to re-install it. For the ten days while I dealt with HP''s TechTards, I was booting off an ubuntu Desktop CD and running live sessions as the only way I could boot my NetBook,

Finally, I made a call to a fellow church member and a one of the TechnoKids dropped off a 4GB thumb drive/re-mix installer to me at work within 3 or 4 hours!

That was three years ago this summer! :approve:

Needless to say, Windows has been perma-banned from my HDDs, with the single excepttion of HP_Maxi. Unfortunately, I haven't gotten the AMD version of ubuntu onto that one yet, but I'll do so when I can double the disk space.

For an 8GB SSD, I'm just going to stick with the devil I know. Triple boot will happen when I can afford the time to mess with it, a nice, spacious SATA HDD and a Feline Retai Box! [] ]'>

Now, if I could just find my pneumatic sheet metal shears, I can get this hack and the 6100 KBD drawer hack on track. the nibbler and body saw are too much work to do the cuts and waaaaay too much filing/grinding to clean them up. }

 

[24bit]

Pneumatic metal shears?

Better power on your CO2-laser on the attic!

 

[Trash80toHP_Mini]

Nah! Air powered tools ROCK! The shears can cut a 1/4" curlicue-coil of waste out of the centerline between two pieces of 18ga Galvanized and leave close to a sheared edge finish on either side! I've got just about every air tool available that'll run off a 15A job site compressor.

Dremel . . . we don' need no steeeenking Dremel! Not with every kind of die grinder and cutoff wheel available in the toolbox!

The air/hydraulic pop riveter is simply AMAZING! [] ]'>

Did this come with an actual drive inside? I've wondered if the drive is a normal 5.25" size. The mounting bracket in your pictures makes it look a bit taller than a normal drive.

 

[Trash80toHP_Mini]

The Cartridge Mechanism is approx half height 5.25" standard, but the AUDIO/SCSI Controller Card attached to the bracket underneath the mechanism, makes it higher than a half height, but lower than a full height 5.25" form factor.

Lots more pics to follow! [] ]'>

 

[Trash80toHP_Mini]

Here are a few more details of the height of the full mechanism . . . sans the controller card underneath . . .

The Cartridge Mechanism is nearly the same size a as a half height optical device bezel at 1.625" + - . . . the controller card & Frame add another .75" + - for a total height of about 2.25" for the frame/mounting Bracket.

SONY MODEL NO. CDU-8001

CD ROM DRIVE UNIT

Nice low profile Sony PSU . . .

TBC . . .

 

[CelGen]

What was wrong with the unit? The disc wouldn't spin?

Be cool if I could salvage parts off yours for mine.

 

[Trash80toHP_Mini]

To tell the truth, I never really checked into why it didn't work with the IIsi.

It just didn't, but the "internal" CD worked fine off a long internal SCSI Ribbon Cable, along with the target HDD sitting on top of it, while the ZIP was happy as a clam on the external bus.

I've bought so much "untested" stuff, hoping it would arrive DOA and hasn't, or fiddling around with stuff that WAS DOA fixing it, and then not having the heart to hack it, that it was actually a relief that it hadn't worked. I just gutted the little B@$^@&% after breaking one of the little tabs off while figuring out how to open it up.

I got this and the CD SC at the flea market along with a Beige Plus, KBD & Mouse. The CD SC works, so it's no-go when it comes to hacking.

Originally I wanted to do a "Snow White" MacMiniCUBE, but decided an ATOMicMicroIIfx w/DVD Tray Loader was a better spin on the original concept.

I've already offered techknight the giblets for hacking a DVD CartridgeLoader and loaning him the SCSI-AUDIO Controller Board to reverse engineer. So we'll see if any parts become available for yours or not.

 

[mcdermd]

I hacked a Toshiba caddy-load CD drive unit into my CD SC case in place of the original Sony. It lives underneath my SE/30 on my desk at work. The original Sony unit would spin up but wouldn't recognize any discs I fed to it. I still have the Sony drive bagged up in storage and I didn't make any permanent mods to the case at all so I could put it back together if I ever found a way to repair the original drive unit.

 

[bear]

The refracting prism that points the laser at the disc gets dust on it, and prevents the automatic laser focus cycle from being successful. The symptom is the drive will accept the disc, spin, make some tiny clicking noises (the focus cycle) and then spit the disc out. Take it apart, and clean the prism surfaces (and the laser lenses, since you're in there), and the drive will work again.

Though, even a clean drive will not read a CD-R.

Well if you ever consider parting with me I would be more than interested since mine has a bit more wrong with it than a dirty optical path.

 

[mcdermd]

Bear, thanks for the advice but that was actually the first thing I tried. Maybe three times before I gave up. It's a complete pain to get it stripped down far enough to reach the prism too.

 

[techknight]

laser diode is probably weak, you could boost it but i would only last so long before pooping out totally, then you would have to find or rebuild the laser pickup assembly.

SCSI-AUDIO Generic Cartridge Mechanism Controller :?:

This board appears to interface with the Generic Cartridge Mechanism at the 12V Power, TTL Signal & Control Levels.

My interest in this board is to have it reverse-engineered by an interested, technically competent comrade. This need only be done to the point of proving or disproving the viability of cloning it. Such a clone could be generally useful for A/B switching a Modern Tray Feeding DVD Player Mechanism at the control board level in order to use it as a 68k or PPC Mac's simple SCSI interface CD Reader Substitute on the one hand, and for feeding its S-Video output directly to a 630-6500 Video System Board's S-Video input for watching DVDs on a Takky or my Takkified Classic's 52" screen Pico-Projection Display or frosted, rear-projection CRT face replacement options.

Even a lowly MehMac/Road-Apple 5x00 could be an AIO DVD Player while retaining the SCSI CD functionality for system maintenance or feeding its Audio I/O. Granted, the players native control board's line level analog output might be superior, especially when coupled with an MP3 CD, but that's a point for quibbling.

Modern, S-Video/Composite Output Budget DVD for Comparison:

Conceptually, I think it would be cool to go in this direction as a generally available 68kMLA Hacking Board, maybe more so than the incredible obstacles presented in retrofitting a modern DVD Player into an ancient Cartridge Based Player Chassis.

Dunno, comments? :?:

 

[techknight]

unfortunately, that mainboard has 2 proprietary ASIC type ICs on it. good luck with the reverse engineering part unless someone wants to decap and microprobe the silicon to figure out its internal logic.
