I seem to remember reading that *some* 800k drives will work with the
64k rom set fitted in a regular 512, but the guaranteed solution is to
upgrade the Mac by installing the later 128k ROM set. These ROM sets
are available from various vendors (see Computer Shopper, for e.g.),
and a kit of ROMs plus an 800k internal drive costs about $280, as far
as I remember (sorry- no Computer Shopper handy to check). The only
vendor whose name I remember is Shreve Systems of Shreveport,
Louisiana. If you decide to upgrade your ROM set, then you can also
add an upgrade board, such as the NewLife, to add more memory (up to
4M) and a SCSI port. The upgrade board costs under $300, plus memory,
as required (about $40 to $50 per meg)
