Expansion
The Macintosh 128K was not upgradable: there was no provision for adding internal storage, more RAM capacity or an upgrade card. Improving on the hard-wired RAM thus required a motherboard replacement (which was priced similarly to a new computer), or a third-party chip replacement upgrade, which was not only expensive but would void Apple's warranty. The difficulty of fitting software into its free memory, coupled with the new interface and event driven programming model, discouraged software vendors from supporting it, leaving the 128K with a relatively small software library. Whereas the Macintosh Plus, and to a lesser extent the Macintosh 512K, are compatible with much later software, the 128K is limited to specially crafted programs. A stock Mac 128K with the original 64K ROM cannot use Apple's external 800K drive with HFS, nor Apple's HD20 hard drive. A Mac 128K that has been upgraded with the newer 128K ROM (A Macintosh 128Ke) can use internal and external 800K drives with HFS, as well as the HD20. Both can print on an AppleShare network, but neither can do file sharing because of their limited RAM.

Famous quotes containing the word expansion:
“Artistic genius is an expansion of monkey imitativeness.”
—W. Winwood Reade (1838–1875)
“We are caught up Mr. Perry on a great wave whether we will or no, a great wave of expansion and progress. All these mechanical inventions—telephones, electricity, steel bridges, horseless vehicles—they are all leading somewhere. It’s up to us to be on the inside in the forefront of progress.”
—John Dos Passos (1896–1970)
“Every expansion of government in business means that government in order to protect itself from the political consequences of its errors and wrongs is driven irresistibly without peace to greater and greater control of the nation’s press and platform. Free speech does not live many hours after free industry and free commerce die.”
—Herbert Hoover (1874–1964)
