Help me get an OS onto my LC III

[iamdigitalman]

ah, my little LC III. Last seen running 7.5.5 happily.

anyways, I am trying to get 7.6 (and later, 7.6.1) on it. So, I hook it to my Powerbook 1400, run the NAD, and copy the 7.6 floppy images over, as well as disk copy 4.2. then, I open disk copy, and get a bunch of errors. First an Error Type 10, then a disk error, then some memory allocation errors, where it wanted more, more, more!!

so, I boot from my flat 7.5 install floppy, and attempt to install a minimal 7.5, and it freezes at the end of disk one!!

I even got a sad mac when I copied the system folder from the NAD to the hard disk and boot off it (why does it matter where a system folder is?)

My theory is something I have in the machine is causing it. My NExT step is to remove the ethernet card, VRAM upgrade, and if I have to, the 32mb RAM stick.

anyone have any thoughts?

specs:

-33mhz 68030 (overclocked from 25mhz, lost my sound in the process)

-36mb of RAM (4mb soldered, 32mb 72 pin simm)

-250mb HD (up from the original 80mb)

-768kb of VRAM (512k soldered, 256k in slot)

-Dyna 10 base T Ethernet card

-12" colour monitor (whatever originally shipped with it), does 640x480 at thousands with the VRAM upgrade, only 256 at the stock 512k.

Try creating a Universal or an LCIII specific boot hard drive (ie shove disk in an external enclosure) using another Mac. Then transplant and report. If the new disk fails, try reversing earlier mods until you find a failure point. The overclocking is hard to reverse so illiminate all other possibilities.

Have you tried the LCIII with different flavours of disk tools? try installing over LocalTalk rather than ethernet, using NAD?

 

[iamdigitalman]

I am working over localtalk with my 1400 as the server. Trying to get the installer to run over localtalk was my first idea.

unfortunantly, I don't have an external SCSI enclosure, UNLESS the one from my old 8x CD-ROM that died will work. hmm, I wonder...

I am also going to try downloading 7.5.3 and install that obver localtlk, and then upgrade to 7.6. maybe something on the NAD does not support the 7.6 installer. I know they changed it to a OS 8-9-esque one.

There's no reason as to why you couldn't use the LCIII's HD in the enclosure from your CD drive.

 

[iamdigitalman]

cool. just when I was about to throw it out too.

it uses AC power as well, no wall wort.

I did have a crack at the insides, and it is a regular insternal SCSi CDROM, and then the molex and SCSi cables hooked up to some board. If I remember correctly, I never took it out because I couldnt.

i'll report bck if I get it working.

Chances are that the external CD-ROM SCSI case has a cable that plugs into the back of the CD drive that allows you to set the SCSI ID externally. Because this won't work on your hard drive, if you're planning on connecting it to your 1400 and doing the system install, make sure you change the hard drive's SCSI ID manually in the jumper settings.

With regards to the original problem, "officially" a type 10 error code indicates a run-time error or discrepancies in the software instruction set with your given hardware. The first thing I'd try is reseating all of your RAM and possibly CPU. Otherwise, I'm afraid it's possible that it implicates your overclocked CPU. But as a previous poster pointed out, best to make that a last resort thing to test. What I like to do is strip a machine down to a stock configuration then try the installation. Since, for example, the problem may lie in mishmatched or flaky RAM chips, and you should be able to install a base System 7.5 with only the 4 MB of on-board RAM.

A NAD system folder more than likely will not work copied over to a hard drive, much the same way that a system folder from a system CD is not bootable when copied to a hard drive. Have you tried completely initializing your hard drive and zapping the PRAM before running the installation on your LC? Or, if you decide to go the external case route and try to load the drive in the 1400 to eliminate the drive as the source of the problem, I suggest initializing it there before the installation.

Cheers,

ok, I attempted using 7.5.3, but that failed as well. and then the machine said there was a problem with macintosh HD. then the hard drive disappered, and never came back.

my next step is to strip the machine down to stock and try that.

oh, there is only one ram stick slot, and all the chips on the 32mb stick are identical. and the CPU is soldered, so I don't think "reseating" it will help. I believe all later 68030s were soldered, but the older ones were socketed.

Big Bird may be right about the overclocking. On some Macs it changes the gestalt ID of the system when you do certain things that deviate too far from factory parameters. The installer on your OS CD is probably looking at the gestalt ID of your system and isn't finding it on it's list of approved models and is rejecting it. You might have to change the gestalt and use a program like Wish I Were... to trick the installer into thinking you have a known Mac for it to install to.

 

[iamdigitalman]

well, I know it won't boot off 7.1 anymore. I get a boot message saying 7.1 is not designed for my model.

I ripped everything down to stock, so maybe that will help.

I think the 250mb HD died, since even Apple SC HD setup can't find it. I have a 160 and the stock 80mb I could drop in to it.

[LCGuy]

System 7.1 will work, but you need System Enabler 003 for it.

 

[iamdigitalman]

I did have system enabler 0003 on the disk, in the right place, and it still did not work.

I guess the gestalt ID did change. Wonder what enabler is needed, since this machine is more or less an LC III+ now.

-digital

 

[LCGuy]

Maybe try System Enabler 308, its for the Performa 450 (LCIII), 466 and 467 (LCIII+). Sadly you can't get that from Apple's website.

 

[Patrickool93]

Ah,

You still need the enabler though

 

[tomlee59]

You can get it from http://home.earthlink.net/~gamba2/enablers.html

 

[iamdigitalman]

thanks for that. I will try to get another HD in there. I am afraid the 250mb one is dead...

-digital

 

[iamdigitalman]

well, I have some good news, and some bad news. The hard drive is not dead. However, the SCSI bus on the LC III is. I pulled out the CD-ROM, and swapped in the 250mb HD. showed up just fine on my powerbook. However, it's still MIA on the LC III, even externally. I then tried my original 80mb drive. same results on both machines.

now I need a new motherboard. So much for that retrochallenge idea.

in the interm, I have shelved the LC III, and put the Powerbook 1400 in it's place, next to my Classic I, since I have limited space.
