Macintosh clone

Apple eventually licensed the Apple II ROMs to other

companies. The earliest, the Bell & Howell Apple II+ was

manufactured by projector and lens manufacturer Böwe

Bell & Howell to capitalize on its stature in schools.[1] The

Bell & Howell Apple II+ was notable for its black enclo-

sure with carrying handle, its coaxial video output and a

stereo jack for headphones.[2] Unlike the Apple II+, which

lacked UL Certification because its case could be opened

while it was running, the Bell & Howell was fully certi-

fied.[3] Apple also licensed the Apple II ROMs to educa-

tional toy manufacturer Tiger Electronics to produce an

inexpensive laptop with educational games and the Ap-

pleWorks software suite, the Tiger Learning Computer

(TLC). The TLC lacked a built in display.[2] Its lid acted as

a holster for the cartridges that stored the bundled soft-

ware since it had no floppy drive.[2]

Wary of repeating history and wanting to retain tight

control of its product, Apple’s Macintosh strategy includ-

ed technical and legal measures that rendered the pro-

duction of Mac clones problematic. The original Macin-

tosh system software was a very large amount of complex

code that embodied the Mac’s entire set of APIs, includ-

ing the use of the GUI and file system. Through the 1980s

and into the 1990s, much of the system software was in-

cluded in the Macintosh’s physical ROM chips. Therefore,
