My brother has given to me a circa-1989/1990 Apple Macintosh SE HDFD. It's in a "carrying" case, includes an external 800K floppy drive, Apple Desktop Bus keyboard and mouse, power cord, manuals, and System 6 install disks.
The system has 2.5MB RAM, a 20MB SCSI hard drive, and a 1.44MB internal floppy.
|20MB Hard drive (with "stuff" on it)|
|System 6, at your service...|
The first thing I did was look into "useful" upgrades: Network, Memory, Capacity.
I found an Asante MacCon adapter for the SE
I found 4 x 1MB RAM SIMMs for the SE
I found this gizmo: SCSI2SD
I can work with this.
And then I ran across this: macrepository.org
