The Plus boots fine with 64K ROMs. It's been done by both myself and Tom Lee. Neither of us used it extensively, but if I'm not mistaken, the 64K ROM was coded to be aware of at least 4MB of RAM if not more, up to the limits of the 68000. If not it definitely supports 512K RAM, which is the base configuration of the Plus. But even in the presence of 4MB installed, wouldn't the ROM simply ignore the higher RAM addresses?
Not sure I understand the Dove Mac Snap SCSI card comment, as it requires 128K ROMs and relies on the encoded SCSI instructions to function. If it were that easy there would not be so many threads devoted to it.
Dennis, your point is well taken, however, I was referrig to the whole package of the Plus, including the 800K disk drive which will probably cost more than the Plus by itself as well as additional shipping. I'm not sure the Plus ROMs by themselves would be so easy to come by either. At least with a functioning Plus, it offers many options aside from cannibalizing the ROMs whereas the equipment you recommend has a one time use for this purpose, as wells the learning curve to use it. For instance, it could be run more or less as a functioning 512K Mac. It could also make for a good parts donor when things start to fail on the original 128K, like the analogue board in particular.
IMHO, the whole Plus is the better deal, unless one wants to get into the business of burning and backing up ROMs, and other related experimentation.
