Modifiable ROM images let us do all sorts of things like add support for more memory via higher density SIMMs (Quadra / Centris 610, 650, 800), add support for non-native and not normally supported hardware, fixing bugs, and so on.<p>I'm considering getting one so I can have a low power, boots-straight-into-use LocalTalk to ethernet bridge with print drivers and printer sharing. Another option is network booting, since network file sharing is so incredibly easy with classic Macs.<p>Fun!
