SCSI on Windows 10 64-bit: Adaptec AHA-2940 (29xx) Ultra, AIC-7870 (78xx), or 29320LPE Ultra 320

When I first started playing with 68k macintosh systems around 1999/2000 (a Macintosh Plus) I connected an external SCSI drive to my Windows 98 system and was able to use an early version of Basilisk II with SCSI pass-through to format the hard drive.  Now 18 years later, SCSI is an obsolete technology, and in general is not supported under the latest versions of Windows and the the Macintosh OS, although I believe Linux still has support.

Luckily a skilled person on the internet has made 64-bit compatible drivers to support some of Adaptec’s cards under Windows 10 (sorry I’ve found nothing for the latest version of the Macintosh OS).   I’ve personally tested the Windows 10 driver for Adaptec AHA-29xx cards with an AHA 2940U PCI card.

Basilisk II: Using Basilisk II to edit my Macintosh 68k bootable image files

One of the most popular features of my site is my ready made System 6.0.8 or System 7.5.5 bootable images for use with 68k Macintosh systems. This entry describes how you can edit my images on Windows 10 using Basilisk II. You probably know what Basilisk II is, but if not, a quick summary: Basilisk II (manual) is an open source emulator of 68k-based Macintosh computers that support 32 bit memory (see section 2) that runs on Windows, OS X and Linux (also works on some other platforms).

Iomega Zip: Using a 100MB SCSI Iomega Zip Drive to setup your 68k Macintosh

I’ve recently been experimenting to see if I could somehow use of my old Iomega Zip drives (a 250MB USB version, and a 100MB SCSI) to move files between my Windows PC and my various 68k Macintosh Systems.   After a bit of experimentation I discovered how I could not only move files, but also create a disk image that would allow me to use my Windows PC to make fully bootable Zip disks for use with any of the SCSI capable 68k Macintosh systems.

Floppy Drive: Using a 3.5″ HD Floppy Drive to setup your 68k Macintosh

Booting your classic 68k Macintosh from a 3.5 inch floppy disk was the most common and the easiest way to get most classic macs working when your starting with a more modern machine (most, but not all, more on that in a bit).

This post focuses on 3.5″ High Density (HD) disks that can be created using modern USB floppy drives.

I will create separate posts describing how to get started using 400k and 800k floppy disks using either a intermediary Macintosh that supports both these the HD format, or using floppy-emu to emulate these old drives.

Selecting your System Software for your 68k Macintosh

As I mentioned in my Setting up your vintage (classic) 68k Macintosh a lot of the supporting information that used to be on Apple’s knowledge base about their older systems has slowly been disappearing. So I’ve decided to capture some of the key information I found useful in this blog. Starting with which Macintosh 68k and PPC Systems support the different operating systems released by Apple.

Not every Macintosh System can run every OS, for example System 8.1 (with a hack) was the last version to support the Motorola 68000 (68k) series of processors, while support for Macintosh Systems with the PowerPC series of processors started with System 7.1.2 and ended with OS X 10.5 (see Wikipedia’s: history of Mac OS).

Setting up your vintage (classic) 68k Macintosh

I recently pulled my old Macintosh Color Classic (with an Apple IIe Emulator Card) out of storage in preparation for a move to see if it still works (last used in 2001)… so far so good.   I also obtained a Macintosh LCIII to setup as my backup system in case the Macintosh Color Classic decides to die on me (need to get a cap job done on both of them).

When I started to look for the guides etc.  that I used back in 1999/2000, I quickly found out that Apple has finally started to abandon these old machines, removing the free downloads and knowledge base articles that vintage mac users have relied on.  Luckily the software can still be found on the internet archive, or sites like the Macintosh Garden and the Macintosh Repository, but it looks like it will be a lot harder to find the information that used to be in the knowledge base.   To help myself remember what to do in the future, and to hopefully help others, I’ve decided to put up a series of posts on how to set up these old systems with links to the disk images and files I use.
