Benj Edwards of Macworld takes a walk down memory lane and lists six obscure Mac computers that saw limited production runs. All the unusual machines were produced in 1990s and include the JLPGA PowerBook 170, the Color Classic II, the Macintosh TV, Power Macintosh G3 All-in-One, Twentieth Anniversary Mac and PowerBook 550c. You can view an image of each model and read more about their history on Macworld's website. It's well worth the read!
