If you haven't been, and you're in the bay area, you really should go here. Sure, the nostalgia is wonderful, but they take their work seriously. Last time I went I was talking with one of the docents about an effort they were taking to get the original Unix v1.0 source collected and compiling.

wooster2• 16 years ago

Seconded. The docents are, IMO, the most amazing thing about the museum. Incredibly knowledgeable, many of them were involved in making the machines on display. It's a truly wonderful place made more wonderful by the people who are involved.

ilovecomputers• 16 years ago

As someone who visits the Bay Area and doesn't have a car, how can I reach that museum via public transit? BART doesn't reach that far down in the west bay.

joshu2• 16 years ago

It's up Shoreline. You can take Caltrain to Mountain View and get a taxi from there.

Or post here and maybe someone will drive you.

wooster2• 16 years ago

There are three bus stops within a 1 block radius.

gojomo• 16 years ago

Google Maps also includes a transit trip planner; enter endpoints as if driving then toggle to the railcar icon (among the car, railcar, walk, bike icons). From SFO to the Computer History Museum it suggests routes using a combination of BART, CalTrain, and VTA bus.

antichaos• 16 years ago

Take Caltrain to get to the San Antonio station. Take VTA bus 40 on Showers St and get off on Shoreline.

jgrahamc2• 16 years ago

Yes, yes, yes. This is a wonderful place. I visited it when it was just a shack on Moffett Field and now it's in the old SGI building.

If you are in the UK and can't make it to CA then a substitute is the National Museum of Computing: http://tnmoc.org/ It doesn't have the depth of the collection seen in Mountain View, but it does have some wonderful pieces. And the staff worked on the machines that are on display. Got the opportunity to show my SO core memory the other day.

They are currently restoring WITCH to working order: http://en.wikipedia.org/wiki/WITCH_(computer) WITCH used the coolest memory ever: the dekatron (http://en.wikipedia.org/wiki/Dekatron). Once WITCH is restored seeing those things glow and rotate is going to make it look like a computer ought to look.

Somewhat related, though the exhibits aren't as nice- The National Cryptologic Museum in Maryland. If nothing else, it's an excuse to venture on to the grounds at Ft. Meade.

When I visited a number of years back, there was a guy selling cell phones on a little folding table outside the front door. Which seemed...odd...for any number of reasons, given the location.

I haven't been to the Computer History Museum (it's been years since I've been in the Bay area), but I did stop by the American Computer Museum in Bozeman, Montana once on a cross-country drive. For something literally stumbled across in a tour guide I was honestly impressed with the collection. It's worth a look if anyone is ever in the area.

Initially I wondered why MacPaint wasn't written in C, but I'm rather grateful it's in Pascal; it's surprisingly easy to read! Although, I suppose Bill Atkinson deserves the credit for that.

trop2• 16 years ago

From http://en.wikipedia.org/wiki/Pascal_(programming_language):

"Pascal was the primary high-level language used for development in the Apple Lisa, and in the early years of the Mac; parts of the original Macintosh operating system were hand-translated into Motorola 68000 assembly language from the Pascal sources. ...the C interface for the Macintosh operating system API had to deal in Pascal data types."

My memory was that C was considered a mainframe and IBM PC language, while the relative elegance and sophistication of Pascal was good style for Macs (esp. when leavened by a bit of assembly code).

varjag• 16 years ago

It's interesting that there was such a notion, as C was never popular on mainframes.

DLWormwood2• 16 years ago

I double-clicked on the .rsrc file, since I still have a working resource editor (Resorcerer) on my OS X Mac. No dice; it’s in the ancient MPW “Rez” format that acted as the original way to store resource information for development and source control before being compiled into the classic Mac dual-forked file format. I kind of wish I kept my CodeWarrior discs handy; they still had a Rez compiler that worked under earlier releases of OS X.

Interesting that they didn’t use the “ellipsis” character in the menus, preferring to hardcode the three periods. The Human Interface Guidelines were clear to use the single character (which does look different enough in the Chicago font), and these kinds of typographic details (via the MacRoman character set) were key selling points for the Mac early on.

lordgilman• 16 years ago

There's a command line Rez compiler shipped with Xcode. The name is case-sensitive.

microtherion• 16 years ago

That can't be right; Rez was a compiler that took plain text symbolic input. Most likely the .rsrc file is just an actual resource fork, encoded maybe in MacBinary format.

Hoff• 16 years ago

Pascal and C were the subject of protracted language wars, with all the usual accouterments involved with those.

Pascal was very common back then; UCSD Pascal and pCode and Terak boxes were all over the place back in college.

Apple was (then) built on Pascal, and this was markedly different from C on SunOS, ULTRIX VAX and RISC/MIPS, AT&T S3 and SVID,and the early (buggy) VAX C on the odd VMS boxes.

(Java still reminds me of that Pascal and pCode implementation.)

In PaintAsm.a:

          .FUNC Monkey
 ;---------------------------------------------------------------------
 ;
 ;  FUNCTION Monkey: BOOLEAN;
 ;
          TST      MonkeyLives                ;IS THE MONKEY ACTIVE ?
          SGE      4(SP)                      ;YES IF >= ZERO
          NEG.B    4(SP)                      ;CONVERT TO PASCAL BOOLEAN
          RTS

According to http://folklore.org/StoryView.py?project=Macintosh&story..., this was used to detect an keypress/mousemove/mousepress-generating testing tool and turn off a few things (Apple menu, File menu, and Quit command, in this case).

ja27• 16 years ago

Always mount a scratch monkey.

cosmicray2• 16 years ago

MonkeyLives (aka low memory global address $100) was a system global that was usually off. If you saw it on, it indicated that the equivalent of a monkey was loose on the keyboard. IOW, don't do anything dangerous when true.

joshu2• 16 years ago

Hooray!

Andy was my officemate when he was working on this. I have a copy of the thread mentioned in the article.

cubicle674• 16 years ago

Andy was my officemate when he was working on this

Can you elaborate on this a bit? You'd have been about 10 at the time (1984), wouldn't you?

ftrain• 16 years ago

I think joshu meant "when he was working on getting the code released."

turnersauce• 16 years ago

What I want to know is why the latest Apple OS doesn't come with a paint program.

barredo• 16 years ago

I'd like to know that too. But there's Paintbrush http://paintbrush.sourceforge.net/

chaosmachine• 16 years ago

I guess they assume everyone just pirates photoshop.

masklinn3• 16 years ago

Acorn 2 has a free version which already packs quite a punch, FWIW.

thought_alarm2• 16 years ago

The closest modern relative to MacPaint is probably the paint program in ClarisWorks/AppleWorks, which was ported to Carbon and runs on OS X.

AppleWorks was bundled with all new Mac hardware up until the switch from PPC to Intel in 2006; I still have my copy that came with my iBook G4, still works in Snow Leopard, still reads files created with the original 128k MacPaint. (And my iBook G4 ran MacPaint v2.0, circa 1987, via the Classic VM.)

These days, there are all sorts of great indie and open source paint programs available:

- Paintbrush: http://paintbrush.sourceforge.net/

- Pixelmator: http://www.pixelmator.com/

- Seashore: http://seashore.sourceforge.net/The_Seashore_Project/About.h...

- Skitch: http://skitch.com/

- Omni Graffle: http://www.omnigroup.com/products/omnigraffle/

Well, the original still works pretty well. ;-) I just used MacPaint to paint this portrait of MacPaint programmer Bill Atkinson:

At this year's edition of Stump the Experts at WWDC, Bill Atkinson went up to the mike and asked the experts what the original name for the HyperCard project was. He got a standing ovation and pimped his photo iPhone app.

Teese• 16 years ago

Well, what was it? and did he stump them?

TetOn• 16 years ago

Wikipedia (http://en.wikipedia.org/wiki/HyperCard#History) reports: Work for it began in March 1985 under the name of WildCard

wallflower4• 16 years ago

The best question was what was the first Apple with an Intel chip.

pepijndevos• 16 years ago

Can anyone tell me what the eyes in the screenshots are? They look like xeyes, but I think that version of Mac predates xeyes. A friend of me claims Apple invented these eyes and the Linux people copied it from them, but I can't find anything about that.

dangrover• 16 years ago

I remember having an extension on system 7 that did that... Probably had been around for a while. There was also one that made footprints go across your desktop during the course of the day and one that made Oscar the Grouch come out of your trash icon.

Someone should take that QuickDraw source code and build a hyper-fast version of X-Windows on it.

cosmicray2• 16 years ago

One other piece of trivia wrapped up in QuickDraw is US patent 4622545 (inventor William D. Atkinson, assigned to Apple Computer). That patent covers the methods required for updating of non-contiguous 2D regions, which could have any imagined shape.
