Summary: What is needed to compile quickly?

-*----
I need to upgrade to the minimal (read: cheapest) Mac configuration
that supports ThinkC development well.  When I look at charts 
comparing performance between the LC and the IIsi, the advantage
of the latter seems to depend greatly on what function is being
performed.  For anything requiring floating point calculation or
quick screen refreshes, the IIsi clearly outshines the LC.  But
for *some* other functions, the LC performs as fast (or faster!)
than the IIsi.  

Question:  How do these machines perform for program compilation?
In particular, is the IIsi significantly faster when using ThinkC
in the compile, run, debug cycle?

(BTW, the Classic II is out because I also need color quickdraw.)

I just recently learned that there are now 8-Meg SIMMs on the market.  
They should have 2 distinct advantages over 16-Meg SIMMs; 1) They are
smaller, so size should not be a problem, and 2) they should be cheaper.
Look for ads in the back of MacWeek and MacUser.

Does anyone have any experience with the Mageic RAILgun 030 from Macproducts?
For $999 you get an 030 accelerator, and 19" monochrome monitor.  Is this
a quality product (compatible with sys 7, crisp screen, easy to install, etc)?

I'm looking to upgrade my SE.  I don't know if I want to want for an Apple
upgrade, but I don't want to get something that will give me lot's of headaches
either.

You might want to look into the Teac 600 MB tape drive.  It can be
had from a variety of vendors for about $700 or so.  I don't know
off hadn what the tapes cost, I have a Teac 150, and the tapes cost
about $30 or so (I think the last set I got were about $24, but that
was a while back).  I expect that the 600 MB tapes will be more expensive.

I would STRONGLY recommend that you NOT buy from MacProducts.  Like
I said, there are several vendors that produce drives based on the
Teac engine.

You might check it out before you buy the "new" Spigot. I don't think it is
going to be one board with both sound and video, but you will have to have
the original video board and the newly announced sound board.

I went to one of SuperMac's VideoSpigot demos just last week and asked about 
an upgrade to the VideoSpigot I had bought just four days prior to 
***MACWEEK'S*** announcement of the sound board and the SuperMac people 
looked totally dumbfounded and confused and then said I was thinking about
the Sound board.

So, I think what you're looking at is $600-700 for the sound board and $300-
400 for the video board and Premiere is no longer bundled with the video board.

Like I said, this is only what I heard (from SuperMac Salestypes) and I don't 
know who I trust less: MacWeek, Apple Sales, or other sales.

Back to the original poster (me), I guess.  The conclusion I have drawn from
this debate is that trying to run the serial interface at over 57,600 baud is
more trouble than its worth; I'd rather write my software to keep traffic
low.

However, the discussion of the RS-422 interface has left me confused.  I
thought that this standard was just a 'fast' RS-232 with most of the 
control pins removed; you can still hook up an RS-232 to the Mac as
long as it runs under 19200 baud.  However, the hardware discussions I've
seen have led me to realize that this may not be the case.  What are
the differences between the RS-232 and the RS-422?  What is the easiest
manner in which to implement the latter (422) in hardware?

	This comes up from time to time (i.e. it's a FAQ).  As long as all
your simms are as fast, or faster, than the specified minimum (i.e. if the
specs say you need 100ns, you can use 100, 80, 70, etc), you're OK.  Mixing
speeds, or using simms faster than required, does no harm, nor does it give
you any advantage.  Which simms you put in which bank does not matter (at
least as far as speed goes; if you're mixing sizes, there are rules for
which bank needs to have the larger set).

	In general, buying faster simms than required just wastes money,
but given that memory prices are so low (and the spread between 80, 100,
and 120 ns simms is so small), it's hardly a major issue.  I've often
ordered simms of a certain speed and gotten faster ones for the same price,
just because that's what the company happened to have in stock.

No, it will not give you any speed increase. Yes, it will "work." as
in "produce the same results as a 16 MHz chip would."

   to boost the main processor to 25MHz? Will the restricted 16 bit capability

Most probably. Except for a 68040 card with RAM on the card; totally
ignoring the LC for most of the time... Except the path to the ROMs
would still be slow :-(

    Any idea what the cost would be? Obviously, it should work out to be cheaper
   than just buying a IIci for this option to be viable. I have quotes of 
   $1400 for the LC II with 4/80, and $2950 for the IIci with 5/80 or $2450 with
   no hard disk. These are university discount prices.

I'd say buy the IIci. It can be upgraded to a Quadra later...

Another suggestion would be, in addition to this, to lock the hard drives on themachines with HDSC setup. Of course if you have apps that need to write temp    files to the hard disks, this may cause a problem.

Oh, great.  This is a real good way to attract future business.  If you were
this dealer, would you bother muttering to yourself:

    Did this person purchase their Mac in another city/state?  If they
    purchased it locally, did I more money than any other dealer?  Did
    they find their purchasing dealer to be a bunch of no-talent jerks
    that don't know what VRAM is?  If I get this fixed for them quickly,
    this person will likely buy from me in the future?

Sorry for the flame, but I've dealt with dealers who have taken this attitude
before, one in my old home state and one in California.  I love the way the
California dealer got snotty when I said I didn't purchase from them; sorry, I
guess I should have flown from Milwaukee to Sunnyvale to make my purchase.

 Even for power users, you can't replace a good dealer when your AppleColor 16
 needs to be swapped out for the third time.  I have no problem purchasing
 commodity items (RAM, VRAM, disk drives, software) mail-order; however, if
 it's a product I believe a may need service and support for, I'll buy it from
 a dealer.

 It's interesting. I called APS and got the driver update. Get Info in the

 but it's not done yet. The last time I used this software to format a disk,
 that disk would no longer mount under System 6! The best that my various SCSI

 to work with this disk."
