As I remember, Apple produced three versions of the Macintosh Plus ROM.  The
first contained a bug that prevented the machine from booting if an external
SCSI device was off.  I guess that other bugs were fixed, too.

I'm thinking about buying an external hard disk for my old Mac Plus (with the
first version of the ROMs), and I was wondering --

  + Should I update the ROMs?  Do I need to?

  + Were other important bugs squashed in the later ROM versions?

  + What would be a reasonable price to pay?  A local dealer offered to swap
    my ROMs for $70-$80 each -- this seems a bit high to me.  A few years ago
    (I think) I heard that Apple offered this ROM update as an official "part."
    Does anybody remember the number?

Thanks for all info.
