[comp.sys.mac] MacPlus - ROMs or board?

mason@furilo.dec.com.UUCP (05/28/87)

Many differences exist between the 512 and the Plus.  Would someone in the
know expound on whether there are any differences (with software implications)
between a 512Ke and a Plus.  In other words, if I have the 128K ROMs and
a bunch of memory, are there any differences of note inherent in the logic
board itself which will make themselves known through software?    

Thanks,
Gary
