AIO Equivalents (68Ks)

SE/30 = Modified IIx/IIcx (minus NuBus slots)

200 = Classic II = Modified LCII (same basic structure but modified to use monochrome compact architecture), LCII = Performa 400 Series (with numbers less than 450)

250 = Colour Classic = Modified LCII (differences include extra ADB port, different connectors (i.e. video), sometimes a 4.5V CMOS, and lack of System 6 support), also LC II = Performa 400 Series (with numbers less than 450)

275 = Colour Classic II = LCIII+ = Performa 460(roughly the same as 550)

520 = LCIII = Performa 450

550 = LCIII+ = Performa 460 (roughly the same as Colour Classic II)

575 = LC475

580 = LC630

There are also offshoots of the 5xx series such as a "Money Magazine Edition" which I think off the top of my head was the Performa 560. These, like the Performa 400s with numbers less than 450, were all the same machine save for bundled software/addons.

Also, the Mac IIvi seems very similar to the LCII/Classic II/Colour Classic trio except it can support an internal CD-ROM.

Another odd variation--sometimes you will see an LC 550 with no CD-ROM. These were budget versions sold to schools.
