Classic II: "This startup disk will not work..."

Let's prove if it's really ruining them!

Does the PowerBook still read them after you put them in the Classic? Also, if the PowerBook doesn't read them, can they be reformatted?

 
When I put them in the PowerBook (from the Classic II, after it "erases" them), it can no longer read them - has to initialize them again. It can do so, and it can then re-image Disk Tools 1 and Disk Tools 2. Can boot the PowerBook with Disk Tools 2, though not with Disk Tools 1. It does read it, but just can't boot from it.

It's worth noting that I get the :) when booting the Classic II from either Disk Tools 1 or Disk Tools 2, but I then get the message, "This startup disk will not work on this Macintosh..." with both disks - though they remain unaltered.

 
So to recap, this Classic II boots from the hard drive? Its just the floppy is not working?

I have had lots of issues with floppy drives, there are all kinds of threads on here that go over how to repair a auto inject superdrive.

They are not really a wear item, but they are a place where filth collects, Sometimes the heads get magnetized and need to be DE-magnitized.

Again with the filth, and dried caked grease in there... Can cause all kinds of issues.

first suggestion is to take both super drives all apart and clean them very well, then relube all the mechanicals.

you might have to re-adjust the head pressure, you can do that my removing the top and bottom head assm, and then adjusting the head tension spring to the next tighter setting on the 3 position adjustable spring perch.

you can buy de-magnitizers at some hardware-dollor stores.

Thanks for the recommendation - will look into that.

When the Classic II is booting from the Disk Tools disks, it recognizes that they're system disks, but it gives the message that they're the wrong disks for that system. Wondering if there is an earlier version than Disk Tools 1.

Think it's odd that I get the same errors on both floppy disk drives, vice just one - especially considering those errors did not exist before last year. But suppose they could both have the very same mechanical errors, simultaneously. If that's the case, wouldn't the drive not even recognize the Disk Tools disks as system disks on boot?

 
have you checked this ?

The capacitors on the Classic I/II analog boards are of very poor quality. Have you checked the +5 and +12 voltage lines ?

per. "nvdeynde" suggestion.

 
Have not checked the voltage on the analog board, but would be willing to try - keeping in mind that I know as much about checking such things as I do writing a dissertation on Astrophysics.

Again, sent off the logic board to get recapped, but not the analog board. Not really excited about going to the time and expense to do so, only to discover that wasn't the issue (as happened with recapping the logic board). Then again, if that's the only viable course of action, so be it.

Will create some System 6 boot disks to see if I can boot the Classic II from that.

just get a multimeter and check the from the header going to the mobo, +12 should be 12volts etc, not less.

did you get that 7.5.3 Disk tool's image they suggested? boot that up.. should work.

i havent done a analog board in a classic II yet, but i am sure i could figure it out.

Okay, can't mess that up, and do have a multimeter.

Before that (and the possibility of electrocuting myself through my own ignorance), will see if I can't find the 7.5.3 Disk Tools.

Edit: Found this, which showed downloads for Disk Tools 1 and Disk Tools 2, both of which I've already got, and neither of which will boot my Classic II (shows wrong system disk error message).

 
Okay, after more searching, found out that the popular Disk Tools 1 and Disk Tools 2 do not work with anything earlier than a 68040, my Classic II being a 68030.

So, found, downloaded, and burned the disks for System 6 ... and my Macintosh spit it out without hesitation and booted to the HD.

Then, found, downloaded, and burned disks for System 7 ... Huzzah! Those worked wonderfully. Found out my HD has some damage that Disk Tools (the one that came with System 7) could not correct - so will eventually have to get a replacement HD.

For now, am initializing the HD. Will then attempt to install System 7 on the machine, then updated to 7.5.3, then 7.5.5.

Should be fun!

 
Thanks for the link. Am now faced with a new challenge: Can boot up with System 7.0 disks and install the system software on the machine.

Am unable to do the same with System 7.5.3 - the machine says it cannot install that system software for some reason, nor can I upgrade to System 7.5.3, once System 7.0 is installed.

Ah, a new puzzle!

 
Regarding OS 6.0.8, put the startup disk for that in and my Classic II, and I got the following message:

"This startup disk will not work on this Macintosh model. Use the latest Installer to update this disk for this model. (System 6.08 does not work on this model; you need a newer version that does.)"

Regarding OS 7.5.3, put in the startup disk, and it stated the following:

"This startup disk will not work on this Macintosh model. Use the latest installer to update this disk for this model."

For some reason, the only OS I can install is System 7.01. It installs without a hitch. Strange, since it had System 7.55 on it before I wiped it. Is there a certain way I must prepare the HD with Disk Tools?

 
You need 7.5, then install the 7.5.3 update then the 7.5.5 update. Welcome to the system 7.5 strangeness. Alot of models will not boot from 7.5.3 because of enablers that they just kind of forgot. The updates should leave the enabler and allow pdating without issue.

 
Hmmm, well only 7.5.3 is available from Apple for full download, so if I need 7.5 to get there it might be a show-stopper.

Still, 7.01 appears to be working fine right now. Just need to find a browser that will fit on a 1.44 FDD and get my Classic II back online.

 
Messing around, found a way to start the installation of 7.5.3 (with 7.0.1 running the machine), even though the installer stated it didn't support the machine, using custom install.

If this works, will post its success. If it mucks things up, then wiping and reinstalling 7.0.1 will be easy.

 
Will google the 6.0.8.L. Read nothing about networking in the linked ReadMe file, so how did you crack the nut on open transport and gaining internet through a LAN (I have a SCSI Asante ethernet adapter)?
