[comp.sys.mac.hardware] MAC-CLONE?

mbpatel@remus.rutgers.edu (Mayur Patel) (05/19/91)

Hi there,
	In Radio-Electronics (Jan '91) they had an article on how to build
	a mac compatible computer.  It is basically a macintosh in an IBM
	case.
	
	It requires an original motherboard (from Apple 128K, 512K, 512KE,
	Plus, SE, or SE/30), IBM pc power supply, a Mac mouse or track ball,
	Mac keyboard, a special 14 inch mono monitor with horizontal frequency
	of 22.5 kHz (which doesn't work with clones), and a special power/
	video interface, a pc clone case which will need modification, and a
	mac floppy.

	If anyone is interested, I have all details.  Just email me if you 
	want them....RE claims the price for this project will run around
	$400 + the price of the motherboard.

	My questions are:
		1-Will any SCSI hard drive work with the SE motherboard?
		2-Will the FDHD drive work in the SE motherboard as a 
		  replacement for the standard 800K floppy?
		3-Can a color monitor be used with the SE via add-on cards?

	I will appreciate any replys...and answer any requests for the 'plans'.

Possibly silly question : Why not just buy a Classic ? It will probably be
much cheaper, particularly since getting the motherboard itself could be a
problem. As to your questions, I can only give guesses (not being a hardware
expert):

1. Can't see why the standard Mac drives wouldn't work.
2. Late model SE's (possibly all models ?) came with the FDHD. You need to 
   have ROMs later than the MacPlus 128K roms for this. 
3. If you mean Color QuickDraw support, no. You need 512K ROMs and a 68020
   or better processor (the SE/30, MacLC, MacII series all have these). There
   is a hack called ScuzzyGraph (I think) which allows you to get 8 color (not
   8-bit) screens on a monitor which is connected to some hardware which 
   connects to the SCSI port. That is all there is, I believe. The SE and 
   earlier ROMs only support the original QuickDraw which had provision for
   8 colors.

Corrections welcome.

I'm not sure if you've been answered yet, but there's a good book out now; 
Build Your Own Macintosh and Save a Bundle- diagrams, prices, sources. The 
only tricky part is that video interface, and that's usually one chip and a 
resistor change in the monitor (ah, you ask, but which one and to what?) as 
outlined in Computer Shopper's Hackenstein articles last year. OK, your 
questions. 1) Not "any" SCSI, but any made for use on any Mac, and make sure 
to get some initializing software with it just in case theirs poops out at 
some later point (SilverLining gets good PR for this). 2)No, the R
OMs won't support the FDHD. 3)Yes, any color card meant for an SE will work 
with a hacked SE, too, but my aren't they pricey!
