[comp.sys.mac] Large

dwb@well.UUCP (David W. Berry) (12/11/86)

Actually, you can create arrays bigger than 32K, they just can't be in
your global data.  Due to the lack of memory mapping hardware on the
mac, and the desire to make programs and data 100% relocatable, global
data is accessed with a negative index off of a5.  Since the 68000
can't handle anything other than 16 bit offsets real easily you can';t
yet have a global data space larger than 32K.  If someone where to
write some really slick code you could still do it, it would
be kinda troublesome and some of the data wouldn't be as readily
accesible:
	move.l	#offset,d0
	move.l	0(a5,d0.l),d0
instead of:
	move.l	#offset(a5),d0
Then again, apple probably limited the size of the global data area
to a word thinking that nobody needs more global data than that
and nobody would go to that much trouble in a compiler...

If you need a large array, allocate it using NewPtr or NewHandle
and go from there.

I have a Mac II that needs a color monitor.  I have the Apple 8-bit video
card already.  My questions:

    How do I determine which 3rd party monitors will work with the Mac?

    In particular, would a larger resolution display (say, 960 X 720) work with
    the same card?  (I would think not.)
    
    If not, is the manufacturer usually the one who must supply the proper
    video interface card, or are there standard ones you can mix and match with
    monitors?

    In general, are there any larger (than 640 X 480) color monitors available
    for around $1k for the Mac?

I would love to hear (soon!) from anyone who can shed some light on this
subject.

I am interested in folk's experience with large B&W (19 inch or so)
monitors. I recently read someone panning Raidus, saying their init
did not work with a number of programs. Anyone else know of big
monitors with problems (or, being more optimistic, monitors with which
they are pleased)? I read the recent macworld on the Nutmeg and
CornerStone monitors, but they didn't seem to try out lots of
software. 

In the same vein, how about large COLOR monitors? I know Supermac
makes them, but it appears that they go to a lot of expense for an
extended pallette of colors. I would be happy with 256. Anyone have
some good (or bad) experiences with COLOR monitors..


Please reply to me, if there is interest I will post the results.
Thanks folks.

It looks like my publisher is going to listen to my pleas for a large hard
drive and spring for a big one. (Interleaf and Virtual really eat up disk
space....)

Is anyone out there using 600 meg drives, such as the La Cie 610 or the
CMS Ehancements 600? These drives seem almost unbelieveably cheap (~$3000).
La Cie has a good reputation, but the drive is internally terminated, which
would be a problem - I'd have to cut the terminators, since this drive
must go in the middle of a SCSI chain.

Are there any others that you would recommend? Although I'm not paying,
$3400-3500 is about all I can spend (read that, all my publisher will give
me).

Thanks for the info.

Can anyone recommend a good manufacturer of LARGE hard disks for the Macintosh?

I'm looking for anything over 160MB in size, although 300-600mb drives are
my prime interest.

Any recommendations?  The drives will probably be used largely for jobs like
mastering CD-ROM data.
