5:00 This is how Satoru Iwata got the contract for HAL to work on the original Golf on Famicom, Nintendo wanted the full 18 holes to be included, but no one else was willing to try to get that to fit on the Famicom cartridge's ROM. Iwata "rather recklessly, said 'I’ll do it!'" and ended up having to write the compression to get it to fit from scratch.

[@billseiler681]

Yes, I remember garbage collect. The garbage collect on the original Commodore Basic would sometimes take a long time. Maybe 30 seconds on a big program. The method of garbage collection was doing lots of searching and copying to do the collection. I believe John Feagens and Ric Weiland worked out a new method with pointers embedded in the garbage to speed up the process. I also remember another bug in the original basic called "the cursor go away bug". Users doing a lot of screen editing on the PET computer would see this bug about once every few weeks. Users were very angry because the PET would lockup (the cursor would stop blinking) and the user would loose the basic program they were working on. We had to rig a PET up to do a lot of screen editing as fast as we could to get this bug to show up so we could track it down. It turned out Microsoft Basic was doing something bad with the stack. If an interrupt happed when the Basic screwed up the stack you ended up out in the weeds and the PET locked up. The screen editing was tied to the cursor blinking and would get you there. John Feagens found the code that was messing with the stack and fixed it. John's patch even fit into the same number of bytes as the original code.

[@rich1051414]

It was incorrectly using a static value of 4 for the length instead of the actual length of a string when garbage collecting. The fix was a very simple one.

I never experienced buggy (trash computer) version, but on C64 garbage collection can take 30 seconds or more during which time the computer will *seem* to be broken. I don't know when Commodore fixed it, but on the C128 every string has an extra 2-bytes allocated as a 'back pointer'. Even though much more RAM is available for strings, the new garbage collection rarely takes more than 1 second ... but users may still consider it a bug when an otherwise responsive program suddenly pauses for no apparent reason (even if only a second).

[@jk-video2716]

I've been writing software since about 1967, including a few easter eggs myself, but I did not know that there was a practical reason for them. Thank you so much!

[@maximilian200057]

What did your easter eggs look like?

[@davidararar]

Great video as usual. Your mention of Ohio Scientific brought back some nostalgic memories. I worked what seemed like many hours at $2.38/hr to save up for my Challenger 1P. I made my parents quite aware of the progress of my savings every week. One night they were late coming home from work, I had a gut feeling about what might be the cause of their delay. My guess was right. About 10 minutes after coming home, dad told me he "forgot" something in the car and sent me out for it. My dad said all he saw was a blur running from the driveway to the front door. I was elated! My first computer with 4K of RAM.

[@vcv6560]

Beep beep, faster than the road runner I'm sure.

[@TomNimitz]

(10:04) I had an Ohio Scientific C8P back in the late 70s with Micro-Soft 6502 ROM basic. I remember having issues running code that used arrays of strings. At some point, the system would stop responding and the screen would periodically flash. Later after having disassembled the code, I confirmed that the garbage collector was to blame. If I recall correctly, string descriptors were stored as 3 bytes - two for the address and one for the length. The garbage collector incorrectly stepped through arrays of string descriptors assuming a length of 4. The result was predictably unpredictable. It was also interesting to see the implementation of the trig functions as as polynomials with only a few terms.

[@bxdanny]

My first computer was an OSI (Ohio Scientific) C1P, with the same buggy BASIC. When the defective garbage collector kicked in, the screen would flash or pulse because the garbage collector was searching through the whole 64k memory space, including the dedicated video RAM at $D000. Each access to it blanked the video output for one clock cycle, producing a tiny, momentary black line on the screen that was usually invisible. But thousands of them in a short space of time were quite visible. Anyway, OSI programmers soon became adept at manipulating BASIC's pointer that controlled where strings were stored in order to avoid triggering the buggy garbage collector. I later acquired a C8P (or C2-8P) DF with dual 8-inch floppy drives, and got a job at an OSI dealership, where I worked on software for OSI's big C3-B computer, with its massive (for the time) 74 MB hard drive. Physically, they _were_ massive: big rack-mounted systems with 14-inch hard drives that would take two men to lift. We sold those systems to a bunch of local companies, and supported many of them with custom software. Thanks, Dave, for mentioning (at least briefly) the often-overlooked OSI line of computers.

[@johnjamesbaldridge867]

Oh!!! You remember the Woz's Integer Basic!!! I remember disassembling that. It's _beautiful_ code! Here is a deep question. There was, for a very brief time, an Apple II program called "The Spreadsheet." It was quietly replaced with something else not as good (I'm trying to remember back to 1979, folks) by sticking a new label over the old one. VisiCalc had just come out. I speculated at the time that Woz had written a spreadsheet that was quietly suppressed so as not to compete with VisiCalc. I'm wondering if anybody has a more vivid memory of this.

[@baksatibi]

20:00 I also recommend checking the comment section under the Pagetable article. You can find some familiar names there, including a certain Bill Gates. ;)

[@xeridea]

Easter eggs like this have been used in many other software projects, and real life. For example, there are maps with fictional streets and cities, as an easy way to catch copying from other companies.

[@georgeprout42]

Most dictionaries also include fake words, for the same copying reason.

[@LiEnby]

And one of those streets appeared in Google maps lol

[@Solarbonite]

Except in the case of raw dictionaries and maps they're not copyrighted as it's collections of facts. Images ofc are excluded, but I think this map/dictionary practice will die out.

[@eDoc2020]

There was at least one case where somebody names their business after the fake place name that was already on the map. A second map company dutifully put it on their new map and were sued by the first map company. The first map company lost. Note: I read this somewhere, there may be some inaccuracies.

[@onradioactivewaves]

Its not only done in software, but in hardware was well. Easter eggs have been used in circuit traces for instance, which could easily prove hardware was xrayed and copied directly by the presence electrically nonfunctional artwork of circuit traces.

[@grantbanstead1971]

The joy of hearing you talk about the UK1010 fills my soul. The garbage collection bug was also on the UK101. Another UK101 bug was a bit set on the MS error codes so syntax error that should have shown as SN Error read S? Error. A syntax error in itself. Garbage collection would kick in when the ever growing stack of variable assignments grew in memory until it hit the program memory and the garbage collection would have to cleaned it up to free the ram. The secret was to define the variables and then they would stay put. Great video!

[@nezbrun872]

I wrote two floating point libraries for the Z80 about 35 or so years ago, one of them was IEEE 754. Back in those days, the real skill was getting it to run fast, and IEEE 754 made it seriously hard on a Z80. To this day, hardware limited microcontrollers' vendors don't implement IEEE 754 as a result to improve speed. The Z80 made it a bit easier because of the IX & IY registers: I'd hate to try to do it for an 8080. The beauty of doing this stuff is that you have to implement development feedback particularly around data structures: you can make dramatic speed improvements by choosing how you implement the mantissa/sign/exponent bit fields.

[@stevejohnson1685]

Did you work for U.S. Software? If so, I really, really appreciate your floating point library. Used it extensively in power metering calibration equipment on a HD64180 (8051-like) processor.

[@JasonKingKong]

Maybe too easily discovered to be considered a true Easter Egg but on the TRS-80 Color Computer and Dragon computers, passing any eight bit number greater than 8 to the CLS command clears the screen and generates 'Microsoft' before the OK prompt. On the Color Computer 3 in the high resolution text screens, this is replaced with 'Microware Systems Corp.' who patched Microsoft Basic for that machine since Gates & Company apparently were no longer interested in doing work on 8-bit Basics.

[@TheBookDoctor]

I don't know which is older, but the TRS-80 Color Computer also had an easter egg in its MS-BASIC rom. The "Wizards" image that was encoded in some unused chunk of ROM, and that IIRC you could see with a USR() command to some special address, or some tiny bit of assembler to load the image or something like that. It would be neat for you to do a video (or a series!) on easter eggs across all Microsoft OSes!

[@JasonKingKong]

Holding down CTRL and ALT while turning on or resetting the Color Computer 3 would display an image of the three Microware programmers who updated the BASIC ROM.

[@nickheyer]

Radio Shack/Tandy had it's own easter egg in TRS-DOS... if you held down "R" & "V" keys while the floppy booted, it popped up the creator's name Randy Cook. When it became public, corporate changed "Randy Cook" to "Tandy Corp" in later revisions. (And being from Detroit, we LOVED "Friendly Giant" being broadcast from Windsor, Ontario!)

[@Nik930714]

My dad has a story of similar functionality, but a bit more sinister. First i have to set the scene - Bulgaria in the 90's. Soviet Union just collapsed, the economy is still shit. Going to court for anything is way to expensive and will bankrupt basically anyone. My bad and his colleagues made controllers for packaging machines. The kind of machines that seal bags of rice or salt, etc. Since he knew that it would be really hard for him to get the money for the controller, after its installed (and getting it before then would be even harder) he had a really nice plan to make people pay. He put a secret function that made the controller brick itself after several thousand packages were made. It came out to around 1-1.5 months of work. The bricking could be turned off from a secret menu, accessible only on boot by holding 2 random keys. If the client payed, he would turn it off and that would be that. If the client did not pay, my dad would just wait around a month for a call that the machine broke. He would fix it "for free" when the controller was payed in full. It its not used for a malicious purpose, stuff like that can be a very nice way to get your money.

There was quite a popular 6502 machine in the UK, the BBC Micro (and its little brother, the Acorn Electron), that went a different way and rolled its own BASIC rather than using Microsoft's offering. BBC BASIC was further developed later for the ARM processor (arguably, for a very long time the only BASIC for ARM!) and is still developed today, by RISC OS Open for ARM, and two cross-platform efforts in the shape of BBCSDL by Richard Russell, and Matrix Brandy (a fork of Dave Daniels' Brandy BASIC).

Not exactly an Easter Egg, but my favorite example of someone signing their work in a way that can't be removed is the Maillardet Automaton. This 19th century mechanical automaton, constructed by Henri Maillardet, can draw pictures and write verse in English and French. When the Franklin Institute in Philadelphia received it in 1928, it was a wreck and not much was known about it. After extensive repairs, they had it write out all of its pictures and poems, and on the last poem, it wrote "Ecrit par L'Automate de Maillardet" ("Written by the automaton of Maillardet"). No other builder of such devices could ever claim it was their work.

I wanted to work on a problem of calculating the interest rate given a principal and payments. I had a math degree, but there is no formula that I could find to do the calculation. Then I remembered Newton's method of approximation. I began coding in basic. Had to learn basic that day. I got a routine coded and debugged. I ran everything I could think of. It was scary accurate! Who wudda thunk? It took me three days to get my COBOL program to do the same thing starting from an already working BASIC program! My MITS Altair 8800 came originally with 256 BYTES. I splurged on a DECwriter. The Basic interpreter was on a small cassette tape. Turns out that the tape reader was a 110 baud modem.

I managed to program a crude version of space invaders on the 8k MS basic using Xs and Os, with a few peeks and pokes to specific memory addresses, the only problem being that you could go and make a cup of coffee between each screen rewrite so it took about ten minutes for a missile to reach the top of the screen and the aliens to move down one row.

I spent so many hours in the computer lab at the College of Aeronautics playing that lunar Lander on our schools PDP 1108 we independently discovered that MCD Easter egg . between that and tower controller and Zork 1 we literally took over the school's computer lab and used up all of the bifold paper we could get our hands on .

What does "Graphic Windows" have to do with BIOS BASIC? There was very limited graphics, and no windows.

[@vrekman256]

@@stargazer7644 hm, turns out that "Graphics and Windows" is just a theory. Head over to wikipedia, in the last paragraph. I think no one knows what it really stands for.... :)

[@stargazer7644]

@@vrekman256 A hypothesis maybe, but certainly not a theory. It makes zero sense to anyone who actually used GW-BASIC.

Was about to have an early night here in the UK. Hmmm what’s this a new Dave’s Garage video? That will do nicely thank you very much

[@DavesGarage]

Morning!

[@videooblivion]

That court case did play out. Jack Tramiel still got the last laugh on Bill. All of that money Bill lost by selling BASIC to Commodore without royalties.

[@locust76]

I imagine all these old devs looking at each other’s source code playing out like the business card scene from American Psycho: “Impressive… very nice… let’s see Paul Allen’s code…” “Look at that subtle uniformity and legibility… the tasteful indentations… oh my God, it even has comments…”

[@markoneil8286]

Dave, keep it coming. Love this stuff

[@scottszego3700]

Dave, truly enjoy these stories. Thank you and appreciate you.

[@FPA4]

The flight simulator in Excel was the trigger that convinced me to switch to Star Office. I enjoyed your book btw!

[@desert123100]

12:20 even though I clearly saw the game I still had that exact picture in my head of what the mcdonalds looked like lol

[@jkbenedict]

As an old-schooler, it still fascinates me how the grammar and hardware support fit into such a tight spot since today, well, everything is so crazily written.

[@stevebowdoin3727]

Dave, love the stories. I have known about and Easter Egg for decades but until this story, I did not realize that is what it was. IBM introduced the System/36 in 1983. At least on the big box 5360, the Easter Egg would show itself. There was a cover over the operator panel. On that panel was a four hex digit display intended for diagnostics. If you had the cover up when you keyed POWER OFF, you would see the hex digits DEAD displayed on the panel. Keep up the good work.

[@MAG_Maldives]

Dave all your videos are great and I hooked your channel with the LED related videos. But this video made write my first comment on your channel. I am from Maldives and I was fortunate enough to spend few hours everyday with an IBM PC in 1984. And without the DOS Diskette - the systems shows the curios OK message. In Maldives and no one to ask no books to read except the BASIC Green binder provided by the IBM with the PC. This videos refreshed that memories of the days I wrote my first software in BASICA to write /print Maldives Language Thaana with a PC. It took me two years to do it. Thanks for this video

Interestingly, PC BASIC's protected saves used the bytes of a couple of trig tables as its encryption XOR values.

[@Rhythmattica]

All This is way above my understanding.. now and then I sort of "get it" , but damn, even those little slithers make it so informative.. Love the channel. (In Oz, I remember selling Vic 20's , C64's , System 80's (trsclone), CAT (a Apple II clone) , Challengewr (IBM Clone) Sorcerer , Pet.. I think there was a peek/poke command that would fry the chip.. ? Maybe just a programmers tale)

[@mauriciobraga]

Hi Dave, its so great to hear all these stories, thank you for doing these videos! :-) I was wondering, how is that possible that Microsoft allowed Commodore to remove Microsoft's name from the boot screen? Wouldn't that be a violation of the license agreement between Microsoft and Commodore? Here in Brazil we had a MSX computer made by two local companies. Both of them also removed Microsoft name from the boot screen and all other places, replacing it by their own name. I always assumed that this would mean that those companies would not have a licensing agreement with Microsoft (or the MSX Association) because I was under the impression that Microsoft would never allow for her name to be legally removed from Basic. Can you give any more information about this question? You mentioned a flat license. What do you mean by flat license?

[@NuntiusLegis]

Flat license: One-time fee allows the usage on as many computers as wished, other than a fee per every sold unit.

[@mauriciobraga]

@@NuntiusLegis thanks for explaining. In this flat license, do you still receive updates / bug fixes or are you stuck with that binary you received to use in as many computers as you like ?

[@NuntiusLegis]

@@mauriciobraga If I understood it correctly, bugfixes and new functionality had either to be done by Commodore themselves, or they had to enter into new negotiaitions with Microsoft. I think most changes in later versions were made by Commodore. C64 BASIC, called "BASIC V2" on the start screen, is actually Commodore BASIC 4.0 including all the bugfixes of that version, but stripped to the functionality of 2.0 to have a streamlined BASIC saving ROM and address space, allowing for longer programs and data segments fitting into the 64 K.

[@chauvinemmons]

The idea you're willing to share with us a peek behind the curtain and how it all came to be and bill is out working another hustle.

[@XmarkedSpot]

I very much like your outros, great funny idea

[@grantbanstead1971]

The ultimate MS language was Quick Basic 4.5 Rarely ever discussed but once ruled the world.

[@NuntiusLegis]

And for the C64, there is a compiler called BASIC BOSS which hit the market too late to rule the world, but which is also great.

[@stargazer7644]

There was also a professional version that was much more complete and powerful that you never hear much about. I think it was called BC 70 or PDS 7.0. QB45 FTW!

[@jasmurphytube]

Love your channel Dave. I imagine big Bill would love to answer these questions!

[@declanmcardle]

Will there be a "plugh" for an easter egg in Adventure/Colossal Cave?

[@dxutube]

I know that on a C64 WAiT6502,0 up to ,63 crashes the machine. Wait6502,64 upwards doesn't appear to do anything but display the next ready prompt. Almost like the Easter egg had been newtered.

[@clydeperrine2959]

Around 1982 I bought a Texas Instruments Ti 99 through my company store at GTE. It used Basic language as well if I remember right. It had an interface that let you connect a cassette player to save and load any programs and games that were written for it. I guess Texas Instruments stayed away from the software copy rights issue.

[@KingSlimjeezy]

Dave really loving these tales! Truly the kind of stuff one can only get from someone with a long and storied career. I'm glad you are having fun with this because its just great geek out tales! Thank you!

[@MarkBarrett]

Floating point does have a flaw that it can't do exact numbers. Simple decimal shifting would solve that problem, and still have the range.

[@stargazer7644]

That isn't a flaw, that's a universal consequence of encoding a value in a fixed number of bits. That's exactly the same thing as integers not being able to encode decimal numbers. Or even handwritten 8 digit numbers being unable to exactly represent a 9 digit value.

[@MarkBarrett]

@@stargazer7644 Base 10 was stupid. We only used it because human kids have 10 fingers. It should have been base 4 or 16.

[@stargazer7644]

@@MarkBarrett The first computers I used from the 60s were all base 8 octal machines. Cut your thumbs off and you're good to go. Bits were arranged in groups of 3, so you had 18 and 36 bit computers instead of the more familiar 16 and 32 bit computers.

[@JacobP81]

21:36 That was hidden really well. I was expecting XOR encrypted ASCII. XOR encryption for those that don't know is a very week encryption.

[@stargazer7644]

That depends entirely on the key used. One-time-pad XOR encryption is completely unbreakable.
