If you want to do vision experiments on your Macintosh computer, and haven’t programmed a Mac before, there are various things you should get for yourself. I’ve listed what I consider essential. The stuff I use. There are lots of baby books that hold your hand while you learn, but the ones that I’ve looked at weren’t helpful for setting up vision experiments. They’re oriented towards producing Mac-like applications with the right look and feel, which is unimportant when the experimenter is the only person that will ever run the program. Be warned that the bible, Inside Macintosh, is intimidating at first. The classic comment about Inside Mac is that you have to have read the rest to understand any part. Fortunately, the new edition, called the New Inside Macintosh--of which only part has been published--is much more readily assimilable. Mac programming is tough going at first, but I’ve come to like it, as the Apple routines are generally intelligent solutions to complicated problems. Anyway, by looking at the sources for the various demos in the VideoToolbox you should be able to get going much more quickly than I did. Good luck. -Denis Pelli

ESSENTIAL BOOKS AND SOFTWARE:
The C Programming Language, Second Edition
Kernighan and Ritchie
Prentice Hall, 1988
This book describes the new Standard C. Most new C compilers are 99% compliant.
THINK C 6.01
A C compiler and programming environment (combined editor, linker, librarian, loader). It’s the best that I’ve ever used on any computer. For a little more money you can get Symantec C++, which includes THINK C 6 as part of the package, but the VideoToolbox makes no use of C++.

Metrowerks CodeWarrior C Compiler on a CD
Until now the main alternative to THINK C has been Apple’s MPW C, which is slow, and clumsy, at least in comparison to THINK C. The only thing I use MPW for is CompareFiles. However, MetroWerks is supposed to release their brand new "Code Warrior" C compiler in January, 1994. Apparently they have copied everything that Symantec did right, and then added their own improvements. There are three versions: Bronze $199 generates 680x0 code; Silver $299 generates PowerPC code; Gold $399 generates both.)

THINK Reference 2
Also from Symantec. This program acts as an online reference manual to the information in the Inside Mac books, volumes I-VI. Highly recommended. $129
Numerical Recipes C Set for Macintosh, 2nd ed.
(textbook, example book, and disk) $90
Useful book and mathematical library in source form. You can read the code, understand what’s going on, and modify it if necessary. From:
Cambridge University Press
40 West 20th Street
New York, NY 10010-4211
(800)-431-1580
914-937-9600
Inside Macintosh: Volumes I to VI, and X-Reference (i.e. index)
New Inside Macintosh: Files, Memory, Processes, Imaging, ...
Designing Cards and Drivers, 3rd edition
from:
Addison-Wesley
(800)-447-2226
You’ll need these books. Apple is in the process of issuing the new edition of Inside Mac. So far they’ve only issued a few volumes. The old edition had numbered volumes--I to VI--the new edition has named volumes, e.g. Files. The new edition is significantly easier to use than the original and includes examples in C, not just Pascal.

ONLINE SERVICES:
UseNet
The comp.sys.mac.programming UseNet news group has knowledgeable active discussion. Experts at Apple often jump in with helpful answers to thorny questions. You can participate in UseNet from your your Mac using telnet (NCSA Telnet and MacIP are both free) to log into a local unix system. Or you might use Nuntius (available by ftp from the Info-Mac archive) if you can get tcp/ip access to a net news server.
CompuServe Information Service
P.O. Box 20212
Columbus, OH 43220
(800)-848-8199
If you can’t join UseNet, then you may want to join CompuServe, to follow the discussions and post your seemingly insoluble Macintosh problems on the bulletin boards, MacPro, MacDev, or Symantec:THINK C, to get free advice from experts. Buy the program Navigator from CompuServe, as it makes CompuServe much easier to use. You’ll need a modem.
AppleLink
(408) 974-3309
ALINK.MGMT@applelink.apple.com
AppleLink is Apple’s bulletin board and email system. It provides some system software updates and technical information. Most companies that make Macintosh products have AppleLink accounts, and you can use the online directory to get their email addresses. You’ll need a modem.
Anyone can submit a bug report to APPLE.BUGS@Applelink.Apple.com. They prefer, but don’t require, a certain format that is produced automatically by a hypercard stack called Apple Bug Reporter, which can be downloaded from ftp.apple.com in /dts/mac/bugs.

FTP is a file transfer protocol used to transfer files across the Internet. FTP programs typically have very rudimentary user interfaces. Some of the bigger ftp servers are now also Gopher servers. Gopher (developed at University of Minnesota, originally for a campus-wide information server) is sort of a superset of ftp that provides a quite good user interface and allows access to a wide variety of Internet resources. Public ftp servers require that you log in as “anonymous and will accept any password, but it is considered a courtesy to supply your electronic address as the password. If for some reason you can’t use ftp or gopher, some of the sites will help you out by allowing you to request transmission of files to you by email.
There are two ways to use ftp from your Mac. The traditional, indirect, approach is to remotely log into a mainframe (preferably one running unix), use its ftp facilities to move the file to it, and then download the file from it. The modern, direct, approach requires that your AppleTalk network have a gateway to the Internet, so that you can run an ftp program on your Mac (provided you have Apple’s MacTCP init, available from APDA for $100; many universities have site licenses). I recommend TurboGopher for anonymous ftp downloading and Fetch 2.1 for general ftp uploading and downloading. Both are free from the Info-Mac archive.

EMAIL:
Your email service ought to have a gateway to Internet; complain if it doesn’t. Here’s how to send Internet mail to various commercial services when you only know the person’s service-specific address:
America Online: “Adam Engst” becomes “adamengst@aol.com”.
MCI: Joe Doe 123-4567 becomes “Joe_Doe@mcimail.com” or “1234567@mcimail.com”.
Prodigy: user ID “abcd12a” becomes “abcd12a@prodigy.com”
HARDWARE:
In my experience a plain old (now obsolete) Mac II is fast enough for most things, but faster Macs can show bigger movies. If you’re going to synthesize images then make sure your computer has a floating point chip. So far we’ve never needed more than 8-bit color, making the obsolete Apple Toby and TFB video cards our favorites, because they work perfectly (unlike Apple’s new video cards--see Video synch), and they’re available for $90 from Shreve Systems (800-227-3971), but, of course, they don’t support the latest large monitors. We also like the built-in video on all of Apple’s newer computers because you can load images into them at extremely high speeds (try the demo TimeVideo), since they bypass the NuBus bottleneck. We use the mouse or keyboard to collect observer responses. We’ve bought a few Data Translation A/D boards to automate our photometry, moving the cards from machine to machine as needed, but they are probably not the best brand.
We’ve done nearly all our research using Apple’s High Resolution Monochrome monitors, which are inexpensive and adequate, though one could wish for higher luminance (100 cd/m^2 peak when new), better high voltage regulation, and dc coupling instead of dc restoration. I suspect that a color monitor might be better regulated and might be excellent used as a monochrome monitor. Use with the ISR Video Attenuator would require that you: 1. use only the green channel, or 2. build a video amplifier to drive all three channels from the single output of the video attenuator, or 3. snip two of the 75 ohm termination resistors inside the monitor and tie all three channels together.
You’ll want a fast CD-ROM drive, mainly to read Apple’s Developer Essentials CD-ROM disk.
You’ll need a modem to call CompuServe or AppleLink, and to dial in from home and elsewhere using AppleTalk Remote Access. You can now buy v32bis (i.e. 14,400 baud) modems for several hundred dollars. Phone lines are still expensive though, so you may want to cost-share by using a shared modem and a single phone line, in which case you'll want to devote an old Mac or buy an AppleTalk Remote Access server to connect the modem to your AppleTalk network.

My department uses a single DAT tape drive (with compression, from APS) and the Retrospect program to backup dozens of Macs every night automatically. We’re very happy with it. Retrospect maintains a historical backup so you can go back to older versions of your data, many backups ago. Get a sufficiently large-capacity tape drive so that you can do unattended incremental backups without having to change the tape.
