I'm curious. Why is there such a push for Haiku on ADB/old world macs? The
Old world rom is buggy and most upgrades to old world machines are hacks
(G3 processor in the L3 cache card slot, etc) limiting their Haiku
performance/functionality. (Requiring a boot to MacOS 9 before booting
Haiku, etc)
Instead of working around the dated/buggy old world rom, maybe it would be
best to focus new world open firmware machines? (imac+ in age)
I admit, i used to love having my Performa 6400, but now it is securely
stashed in a closet.
Just a thought. Old imac's are cheap and plentiful on ebay and would be
a-lot less hackish/buggy :P
