LC 475 with IBM Hard drive

Hi Austin,

What happens if you try to boot from a floppy with an appropriate system version (e.g., the Network Access Disk 7.5 here or a Disk Tools floppy) without any external units at all connected to the SCSI port?

Also, try placing a CD-ROM extension (such as Apple CD-ROM 5.4 here in case of an external Apple CD-ROM drive) in the System Folder of the Network Access disk, and boot from that floppy. That way you should be able to use the external CD-ROM drive with any disc.

In order to make a new hard disk appear on the Desktop, it has to be formatted in a correct way. Apple HD SC Setup is intended for Apple-branded drives. Drive Setup 1.7.3 ( here) can handle some more drives. Otherwise, you would need a third-party Mac formatting utility.

Austin,

One way could be to seek assistance from a user group in your area.

As Jan suspected, you will not be able to boot from the CD with the C key, because the CD for that Mac was an add-on. The Driver for the CD drive is not in the Mac's ROM, and it does not understand how to boot from a CD until the Driver is loaded.

Minimum software is OS 7.1 with Enabler 065. Maximum is 8.0.

The Disk Tools from one of those systems will allow you to initialize the Hard Drive, and you can sometimes "Drag and Drop" the minimal system from a diskette onto the Hard drive to boot it up.

Give us an idea of what major city you are near, and folks can provide more specific advice.

If absolutely necessary, it is possible to create certain bootable Mac disks (the Network Access disk is one example) on a Windows PC equipped with a floppy drive. A suitable version of Aladdin/StuffIt Expander for Windows would be needed for the decoding and the decompression. The resulting .image file can be written to a 1.44 MB diskette via a program such as WinImage.

However, on a PC it is either difficult or impossible to modify a Mac disk created that way without disturbing the boot blocks.

There have also been reports (for instance, here; I have not tested this procedure) about making bootable diskettes on a Mac OS X machine with a USB floppy drive.

Here is a list of MUGs in Arizona:

Understand that not all may be going concerns, as the site relies on reports from individual groups. If one disbands and they don't notify Apple, it stays in the list.

You should be able to find floppies in many computer or office equipment stores. Normal IBM/PC-formatted 1.44 MB HD diskettes can be used (they can be reformatted to Mac whenever necessary).

If your LC 475 had been fully functional with the Apple hard drive, then you could of course have created boot floppies there (in Disk Copy 4.2 or 6.3.3), and manipulated disks. However, since the hard drive stopped working, I have to assume that no storage is possible there even if you could boot from another drive.

One more thing, could you please indicate exactly what happens when the LC 475 does not boot with the new hard drive installed (sounds, background, icons et cetera).

" I placed jumpers on the unit attention jumper and enabled termination on it with another jumper."

On the jumper block, the factory default setting for JP5 (" Disable Unit Attention") is OFF. I'd remove the jumper that you placed there. Additionally, with the external SCSI CD-ROM drive that you're using, do you have a terminator plugged into the unused SCSI (DB-25 or Centronics-50) port on the rear of the drive? If not, you need to do so. I have an LC III (same design as your 475, but with the 68030 processor) and used an external SCSI CD-ROM drive for booting from the installer CD. It always worked without any problems.
