So the actual first thing I need to do is to make a bootable floppy. It works perfectly fine with the SCSI2SD, however it doesn’t come preinstalled on a bootable floppy. The solution is to use the third-party disk formatter Lido 7.5.6. They don’t recognize the non-Apple drive by default, and even if you get a “patched” version which does, the resulting disk will have data corruption problems. However, I’ve found that those programs don’t work well with the SCSI2SD. The usual process is to boot from a floppy and use either the Apple HD SC Setup (for System 6) or Drive Setup (for System 7) program to format the drive. The first thing I want to do is format that 1.75 GB drive with an HFS filesystem.

I’m using the aforementioned SCSI2SD to simulate a single 1.75 GB hard drive, on which I intend to install System 7.5.5.

I’ve installed 64 MB of RAM along with a GGLABS MACSIMM ROM replacement.

Now it’s time to get that disk formatted and a working system installed, but to do so I’ll need to create a boot floppy first.Īs a quick recap, at this point I have a Macintosh SE/30 with a working floppy drive. In Part VIII of this series, I finished prepping a 2 GB SD card for the SCSI2SD that will serve as the primary disk for my vintage Macintosh SE/30.
