personal computer by Apple

Rolled out in January 1989, the SE/30 was the first compact Mac to come standard with the FDHD 1.4 MB floppy drive (a.k.a. SuperDrive) and support more than 4 MB of RAM. It was essentially a IIx in an SE case.

Although advertised as a 32-bit computer, the SE/30 ROMs were “dirty,” containing some 24-bit code, meaning it could not run 32-bit applications without new ROMs (which Apple never produced) or a software patch. To use the SE/30 in 32-bit mode, you need a free copy of Mode32 from Apple (search the page for “mode32”). (You only need 32-bit addressing if you have more than 8 MB of memory.)

The SE/30 offered the power of the IIx in a minimal footprint configuration. With the built-in 9″ screen, it was a popular network server.
