[comp.sys.mac] HELP! What makes a MacPlus?

	HELP!

	I have one of the original 128k macs that I upgraded to a 512ke
	and then to 1024k. Some of the software I am trying to use that
	requires 1 Meg still will not run because my machine still looks
	like a 512ke. Even MacEnvy identifies it as a 512ke with 1 M of
	memory.

	What do I need to do to make this machine look like a MacPlus?
	Do I need a new clock chip? A SCSI port? Also, are there
	software work-arounds for this (e.g. can I just write a "machine
	type" byte in memory to fool this software that won't run)?

	Any hints would be much appreciated.

Thanks,
Charlie Farwell

	HELP!

	I have an original 128k mac that I upgraded to a 512ke and then
	to a 1024ke. Some of the software I am trying to run that
	requires 1 MB still won't run because it complains about my
	machine not being a mac+. Also, MacEnvy shows my mac as being a
	512ke with 1 MB of memory.

	The question is, what do I need to make this machine look like a
	mac+? I know it's missing a SCSI port and a new clock chip. Do I
	have to have these, or is there some way I can fool the software
	into thinking it's a mac+? Is there a configuration byte or some
	such thing I can manually modify to achieve this?

	Any hints would be greatly appreciated!
