[comp.sys.mac.hardware] What is the best way to expand a 128k to 512ke/1024ke Mac?

erd@tut.cis.ohio-state.edu (Ethan R Dicks) (01/15/90)

A friend of mine bought a beat-up 128k Mac for real cheap.  Among other
problems, the disk drive does not eject (sound familiar?)  I am looking to
help him upgrade it.  Can I just chop out the 64kbit DRAMs and insert
256k chips?  Is there more to it than that?  Is is better to chuck the
motherboard and put in a Mac+ motherboard?  What is the cost (approx)?
Are there any alternatives to paying Apple $350-$400 for a new internal
drive and ROMs?  I can get ROMs mail-order, but what about disk drives?

Thanks for any answers to any of my questions,
-ethan
