![]() ![]() First, I copied everything from the external drive to my internal hard drive by dragging the drive icon onto my main drive’s icon. After installing Mac OS 8.1 on the external drive, I also discovered it wouldn’t work with the version of FWB I had used. One key to running Mac OS 8.1 on older Macs is not updating the hard disk drivers. Then I ran Born Again, which is pretty much a very sophisticated, very powerful installer script. I formatted the external drive with FWB Hard Disk Toolkit. I connected an old 2 GB external SCSI drive, my son’s external 24x CD-ROM, and booted the IIfx. I’d even use the IIfx now and then to look at Low End Mac on older browsers and at reduced color levels that Power Macs don’t support. ![]() It’s the perfect height for use as a monitor stand. This machine was once my email and web server, but I retired it when I discovered that it couldn’t restart itself after a power outage.įor several months, the IIfx has been connected to a MoniSwitch ADB and supporting my monitor. ![]() I’d upgraded it to 32 MB of memory, installed an 8-24GC video card, and even had an ethernet card in it. My guinea pig was my trustworthy old Macintosh IIfx, the $10,000 computer I picked up for $200 a few years back. To run Mac OS 8.1 on most 68030-based Macs, you need at least 12 MB of physical memory, 120 MB of free space on an external hard drive (or possibly a separate partition – I haven’t tried that), a Mac OS 8.1 CD-ROM, and a CD-ROM drive. The latest is Born Again from Brochner Software, which is a far more elegant solution – and one that supports more models. Unless you’re very creative, they were right.īut where Scott Barber led, others have followed. It was a fairly convoluted method that only worked with a few Macs and required first booting from an older OS, then from an OS 8.1 hard drive – but it was possible.Īpple said that Mac OS 8.0 and 8.1 required a 68040 or PowerPC CPU and 12 MB of physical memory. 2000 – It’s been a couple years since Scott Barber posted information on running Mac OS 8.1 on a Macintosh IIsi. ![]()
