"Twelvety-eight thousand" sums up Bisqwit's coding. If it's more efficient and quicker to say or do, then use it.
I had to rewind because I thought I was going crazy
@@MikeDawson1 Yeah same :-D
1:29 😂
Also - 9:43
I had to rewind too, what a brilliant way to say 128,000.
I too put considerable effort in revealing the Norton UI font, so it's heartening to see someone else manage it.
How did you do it? If I may ask.
@@Bisqwit I'm assuming Norton hid their font UI to prevent copy cats? I'd like to hear how both of you accomplished it!
@@aidenator00 I think "preventing copy cats" was infinitesimally low on their list of priorities. It was just a matter of not providing a glitchy experience to users.
@@Bisqwit SideKick 2.0 was the key, letting me switch to a character table *while* running Norton Desktop.
@Kawa Thank you for replying eventually! I did this in dosbox-debug, which lets me edit the graphics memory while the program is running.
I've missed your content bro, you're a constant inspiration!
10:52 - "But naturally, I anticipated them anticipating my trick..." - Amazing! I would love to go to the same lectures as you at university only to see some more tricks anticipated! I wish you all the best learning (or teaching) experiences there!

I just read your comment when he was saying that while scrolling the comments down lol
this guy goes to uni?? it's uni that needs to go to him
Now that was fascinating! I sorta knew how text mode works, but I had no idea about the cursor trickery or the fact that Scream Tracker runs in text mode.
I know the why and how, but still fun to listen to you talk about it XD it just fans the flames of my nostalgia
I miss your videos man...
I am glad to hear that!
If I remember correctly, when you set a password on one of the Norton tools, it modifies its own exe towards the end with a substitution cipher and prompts for a password when started. I clearly remember decoding that cipher to figure out the substitution table. When you didn't have a password set, the actual bytes corresponded to NOPASSWORDISSET!. The maximum length of the password was exactly 15, so you couldn't get that last exclamation mark in there by just typing a password.
man, this really gets my inner child excited. I spent so much time in DOS and Qbasic and wanted so badly to just make my terminal and text editors look cool, I preferred DOS to Windows. This channel is basically what I dreamed about back then, just amazing
Same ❤️
I have to admit the text-based cursor is pretty clever, though the "feel" of almost all cursors in text mode back then was pretty terrible. I'm designing an 8-bit computer, and I just decided to add two sprites -- one for the mouse cursor and one for the text caret. As long as the sprites are simple enough, the extra hardware isn't a big deal. I'll consider reserving some characters for use with the text-based desktop UI.
Out of curiosity, what are you designing a 8-bit computer for?
@@Bisqwit It's just a hobby retro machine, designed to run with 64K DRAMs from the 80's. I'm new to system design, so it's probably not that good, but it's a nice learning experience.
It all started with my fascination with the differences between RISC and CISC, and my frustration with the 64K memory limit of the Z80 I was originally using. So, I decided to make my own hybrid CPU with a linear address space that can do computes on loads, but cannot modify memory in-place like most CISC processors can. That makes it about as powerful as a 68000, but costs about the same as a Z80/6809. My ISA and CPU simulator aren't finished yet, so the rest of the machine is a bit up in the air.

Thank you for your answer. I wish you luck and more fun with your project!
"note: 1 + 1 = 2" Thanks, Bisqwit. The math was starting to throw me ;)
Also, great to see you posting videos again! I love your content!
Great piece of history and explanation, thank you. Wishing you success in your studies!
Bisqwit is back. 😭
What a great way to end the year.
The legend is back.
Very nice.
EGA/VGA can be set up to have two fonts active simultaneously- in this mode attribute bit 3 doubles as "character select". So Norton didn't really have to sacrifice characters from the main font. My own editor 'Fontraption' exploits this to let you edit every character without disrupting the UI (sources are available).
And BTW, technically CGA and MDA both came first, since they were both available at the PC's launch. :)
Happy new year!
Yes, you can do that at the cost of losing high-intensity colors - which I think they didn’t want to do, as they used bright white everywhere in their UI. They didn’t also want to use high-intensity everywhere, because then black text wouldn’t work. Thanks for commenting and happy new year!
.. and remembering most people could not afford the CGA at its launch, that loss of an intensity bit (eventually) would have decimated the mono software market too ;)
Since they were using EGA/VGA text mode anyway, they could have used a carefully-selected 8-colour custom palette; or perhaps even deliberately avoided disabling high-intensity; or maybe even a combination of both. With sufficient effort, Norton's UI could have befuddled even the best geeks.
Maybe. But they didn’t have three centuries worth of geekdom to obsess over the implementation details; they had a product that had to be put to market.
Great explanation on something I just took for granted
Good luck with your studies, hope to see more awesome content
There are always a pleasure to watch! It's intriguing to see how these old systems worked, even if such workarounds aren't needed anymore there's value in learning about them.
Missed your content! This is pretty cool information! I’m always impressed with the detail that you go through and your presentation of information is very clear! Awesome job!
So happy you're back! We've missed you.
I hope you are well man.
Good seeing and hearing from you again.
I find videos like this super relaxing. Please keep going!
It's not Mario guys, it's Grand Dad
This is too old to be Grand Dad; this is Great Dad! AKA: Fortran

Very glad you got into university, wish you a nice course bro, your videos are amazing and we missed their simplicity on the exposure and reading
Absolutely superb work as ALWAYS sir. Have a fantastic 2022. Make sure you maintain a good mix of work and play at your university, - can't work all the time, your mind needs rest too. You're an inspiration.
Great video! Never knew about the trick, it's really interesting to see the ingenuity of programmers at play like this. Best of luck with your studies!
Lots of love Bisqwit, you're a great p e r s o n
Happy New Year Bisquit. Your videos are brilliant!
That was awesome! ☺Thx Bisqwit and a happy new year!💫
your videos never fail to inspire bisqwit, never stop creating content!
Great to see another video from you, always so unique and fascinating. Have a happy new year and good luck with the university speed run challenge!
Ooooh boy! How good is to see you again.
"Person" sounds like censorship. Like that USSR leader that was painted out of a photograph. "Person."
Er'body loves you, Bisqwit. Happy festivites, best wishes in 2022! Life is strange!
It's nice to see a new video by Bisqwit. The videos have such a unique style to them.
What an awesome video, thank you for taking the time to make it!
Nice to hear you again. Happy new year!
Thank you for this video! This was very interesting to learn. Good luck in your studies!
Super video, I love learning cool new stuff about things I never imagined I would ever be able to understand at the time!
Never knew they would need to do so much work to even show the mouse cursor over text. Awesome video! Thank You!
Kiitos tästä erittäin mukavasta mielenosoituksesta ja onnea suomalaisille uudelle vuodelle.
Mielenosoitus = protest (as in, a rally full with picket signs, megaphones and speeches; literal meaning is evince one’s opinion). Doubtful you meant that.
The content of your videos is so amazing - I'm floored by your ingenuity in getting the mouse to work. Good luck with your studies.
Thanks, although you maybe misunderstood something because Norton tools are made by Symantec, not by me. The mouse cursor thing was specific to Norton tools.
@@Bisqwit Ah, I re-watched in non-2x-time and now I see it's a Norton thing. Yeash, I need to slow it down! Always a joy to go through the comments on these vids too... your channel attracts a sophisticated audience!
I have Missed you, bro! love your videos... It points to what I dreamed to achieve while learning "Turbo Pascal" on MSDOS, such nostalgia.
it's actually quite impressive what some old software did accomplish with such limited resources. the efficiency was not an additional good, but a need. nice video as always, keep up the good work and good luck in your studies!
Glad to see you posting again!
the editing and the humor, it send me off haha, great job bisqwit
Happy New Year, and Welcome back. We have missed you.
Yes you are back! Awesome explanation!
Fascinating stuff! Thanks for sharing.
Good old PERSON from the Super PERSON Brothers
Happy new year @Bisqwit - it's great to see you posting again, and best of luck in your studies!
Very clever trick! Interesting how it's fast enough for a full refresh rate.
Thank you for your video! It's so informative and sweet to watch.
You know things about PCs and DOS that I wish I had learned when I was a student at NYIT. I had no idea you could change the font that's used in text mode; it gives me the idea for some projects that I wish I had time to try myself.
Oh, and thanks for introducing me to Kdenlive.
Thank you for writing. Yeah, there is so much I also wish that I knew back in the day. A chance to sort of redeem or relive my past is one of the reasons I am doing these videos, too.
Great to see you again.
I just love your videos. Good luck with your studies.
Thank you!
Mind-blowing!!
Idea of animated fonts is really cool.
Would try to implement them for my editor.
Great videos as always!
always excited to see your content!
This is brilliant. Thank you!
Happy new year Bisqwit! And I wish you a great luck for the university! :)
Happy to hear you're studying! Of course that sort of thing takes priority over youtube. Toivottavasti kaikki sujuu hyvin, pidä kivaa siellä.
I'm fascinated by all the clever tricks developers used back in ye olden days. They had such limited resources but could still do so much cool stuff.
I can 100% relate to university and life eating up all the time! i will finally be finished in may of 2022.. I love your content and will be a member forever! :) I always look forward to new content and I am always rewatching older videos to see what else I can learn! :) Thank you!
Thank you for your heartfelt comment (and your support)! Now, I could adjust my schedule and avail more free time to myself, but reasons explained in other comments are why I am speedrunning through it.
@@Bisqwit For sure... there are always potential sacrifices.. however.. priorities are important for the long game. :)
I am so happy there's another Bisqwit video
Amazing information and well explained!
That was fascinating.
I'd always wondered this back in the day.
Great video.
CGA too has that register bit that allows to choose between 16 background colors and blinking. Actually, it is set to be 16 colors by default, and it is MS-DOS that toggles it to blinking.
You are awesome. Hope you have a great 2022.
First time TH-cam's algorithm suggested something I actually want to watch and I was not disappointed. A great way to start 2022, thank you.
Subscribed.
Thank you, and a have a nice new year!
I cannot believe he actually did it. I've been waiting for this specific video for so long... THANK YOU BISQWIT
I been always fan of terminal gui's. I loved the magic behind the cursor
I just found your channel today ... your content is absolutely amazing!!!! Thank you!
Bisqwits the only TH-cam with over 100k subs that I know to read and either like or respond to almost every single comment! So awesome
A new video!!! I love tricks like these. Keep it up!
I know nothing of computers or coding, I just like watching and listening to smart people
Good video as always Bisqwit!!!
Oh my, thank you so much. I was wondering how the hell that was possibile (I mean the smooth mouse moving in text mode) since mid 90's. I had a suspect how the trick was done but I was not sure I was right until now. 12 years old me is very happy now. Thank you muchly!!! ❤️
I hope you can pass "Introduction to Programming", bisqwit :)
The courses listed on that screen are only those that I have completed already.
@@Bisqwit ah, job well done
@@Bisqwit did you pass Mathematic for Physics? Why so low grade?
There are three Mathematics for Physicists courses. I completed the first one (got 2/5), abandoned the second and didn’t go for the third one.
The course is essentially a crash course of a subset of university mathematics for those who major in physics. I major in mathematics. Basically that set of courses speedruns through mathematics topics at _way_ _way_ faster pace than I am prepared to put effort into, given that I am also doing a heap of other courses simultaneously. I am majoring in mathematics, so I will learn the stuff eventually, at my own pace.
I always enjoy ur videos. Thank you for making them.
Awesome walkthrough! Even though I mostly knew how it was done since early home computers also use the same "trick" for graphics, e.g. C64 etc.
Good lock with your studies!
Thank you for watching and commenting even if the information was nothing new to you!
@@Bisqwit Always! One has to support one's favourite creators ;) (especially now when the video frequency has decreased)
New video!!! Nice gift new year! Happy new year Bisqwit!!
You're finally back!
Awesome content and explanation!
I always learn something new when watching your videos, they are inspiring.
Happy new year!
Hyvää uutta vuotta!
Love your new intro anim too!
nice to see you back bro
I saw your comment on the heated blanked cat Video and instantly saw that you uploaded a Video. This is quite funny
Thank you for this interesting video! We really appreciate your time and dedication to share your knowledge. Thank you Joel! 👍👍👍
Mr Bisqwit, thank you for an amazingly inspiring video.
A few months ago, I went to open up QB for the first time in many years. As I recall, it was actually with the purpose to follow along with one of your videos in which you prototyped some 3D rotation in QB. Good fun!
Of course, the cursor in QB (Same as ms-dos's text editor etc.) doesn't apply this same trick to for the mouse cursor - Instead, providing a somewhat 'quantized' experience, that constrains the cursor to specific character positions.
In any case, I was expecting that going back to this IDE would be like putting on an old pair of jeans. Mostly it was, however I was surprised at how tricky it felt to use the mouse. Back in the day, it used to feel so comfy and intuitive!
Very good stuff. Such a short video but I bet it took enormous amount of time to produce.
When Bisqwit releasing a video is bigger hype than New Year’s eve. 😀
I like how he said "person" to avoid copyright claims xD, also this video is pretty informative, might use it sometime! And I think they made Norton systeminfo look like this to make it similar to windows 3.11
missed you, your content is the best!
Another thought occurred to me.
Your CS teachers can consider themselves very lucky. What have you taught them all? 😁That is certainly a special and funny situation. Your teachers have certainly never had a student with such a high level of competence!🙃
Most of the courses have massive participant lists, so the teachers don’t particularly have opportunities to notice individual students. In some cases, the curriculum is also rather demotivating and pushes talents down to a common level. However, after only the first period, I got an offer to be a (paid) supervisor on the course _Introduction to Databases._ I accepted the offer effective the next period.
I think, chances are the same could have also happened on the two programming courses, if I had taken them normally instead of substituting both with general exams.
I've wondered this for years
Yay! Bisqwit is back!!!
Thank you bisqwit
