Thanks, very useful, many times knowledge got lost and people are desparetly looking to find this info. Very good article as well!

Thank you for your video! I have PEEP, and was looking other options. PEEP has a great navigation, and handles large files, but QL offers some great features that compliment it. Also watching your other videos. I've never heard of XCCP or EPEX and I'm sure I'll discover more.. I've learned a lot from your videos! Much appreciated!

Reminds me of Wouter van Oortmerssen's FALSE.

OISC, or SOTM, architectures, are inefficient and overrated. They waste valuable time that even RISC can save.

I have written a subleq interpreter in x86-64 assembly for Linux. Not quite done with it, yet. I have not implemented any input routines, yet, but have implemented 3 output routines. It interprets binary files. Believe it or not, I can assemble subleq assembly with a regular assembler into the binary file. I've used both fasm and nasm. Macros make it easy, but they're not necessary. I am working on She-bang support, too.

Can we have the teased video on the further techniques on scrolling particularly for games?

you can see a doctor about ED

I had speedscript at the time (typed from hex dump from Compute's Gazette, I believe), but once moving to the C64, there was also a speedscript for that, since C64 is also lacking 80 columns. I like the way it works, reminds me of Wordperfect a bit (except for the code section separate from the pure text section). It's also a pity tat none of the native Document Editors for the VIC20 support any 40/80 column card... How did you print/show the print output ? a real printer with a scan for showing it on screen ? or a simulated one that generates PDF or images ?

If you don't mind the character codes from moving around in the 224 bytes of the screen in sideways mode, you can scroll quicker by moving the codes (rotate around and clear the lowest line) when scrolling up (to the right). Also, with a Lumacode extension to an RGB2HDMI connected to a turnable widescreen HDMI widescreen, you could have vertical page properly depicted. Additional, if you were to implement an ASCII BASIC, or perhaps a more simple turtle program, you can implement graphics routines that can write into the "textscreen" as well.

"I love Ed on CP/M" is like saying "I love to be humiliated and tortured by strong Woman". Whatever gets you going mate!

TNX 73 🤣 DO5NET Peter

That is so pretty to look at. I didn't know it could run this fast

I want the exact opposite: - 1 pixel wide fonts on the C64 - default white on black without border - Destroy Petsci, and have both fonts act as normal lowercase/uppercase. - extra challenge: make the tokenizer recognise Basic in both cases.

Vic-20, 32k expansion, black and white portable tv, 1541 drive, seikosha printer. Got me through university….. 😂😂😂😂😂

And people blast me for loving and using VI instead of modern IDEs... 😂

On the VIC 20, this method wasn't very common. It's much easier to just shift the BASIC start address (see my video at kzbin.info/www/bejne/Zoazi6KAqZ2np5Y -- this is for a 16K/24K RAM expansion, but on unexpanded machines it works similarly, just remember that the low BASIC start address is different on unexpanded machines; find out with PEEK(44) ). I.e. you write a small BASIC program in lower memory (to set the start address to upper memory) and then in upper memory another program (often just a SYS to the machine code). Now if you set the start address back to the beginning, if you SAVE the program, it'll autosave from the start address to the end address, and it'll remember any machine code (and data) you've stored in between.

Amazing such a program to run on a 22-column VIC-20. Nice...

I grew up on Commodore VIC-20 as a kid.. still have one, will play with it when I have more free time... ah, BASIC program, but that 22-column screen kinda sucks.

I always didnt like VIC-20's 22-column screen...Nice to see it can be increased slightly without extra hardware.

I'm not sure what is more satisfying ... the simple-to-follow & very informative tutorial or the satisfying clack of the keyboard ... 😌

Hello! This is very cool! I see there haven't been many updates lately... Have you done anything more with this? Is there anyplace where the public can download the code and run it? Thank you so much!

Very nice. Do you have a source where the table at 1:30 can be downloaded or obtained? I assume that the hex loader at 5:17 would also work on the C64.

Just taking my first steps into Commodore assembly, and this was very useful, particularly the use of the M command for entering the data table and managing the forward references. I have one of these newfangled THEC64 things, so I have disk drive emulation and can "afford" to run the multi-part assembler programs, but it feels like a pain in the behind to use when starting out writing small programs to get the hang of things. Hand assembly with manual entry into the monitor is currently still the best option for me.

A lot to remember which is why I’m putting together a cheat sheet based on your excellent video.

Site down?

Thank you, this is really helpful. I have resurrected my childhood Vic20 and this is a great shortcut to writing and running new programs. Your pace and explanations are great to accelerate my explanation of getting back into the Vic20. Well done.

In the old days I found ANYTHING less than 80 CHARACTERS INTOLERABLE. I would never have tried 22 characters. They tried to solve it well, but ... please ... A TYPEWRITER would have been better. I hope that nowadays NOBODY is using the VIC20 for WORK right?

The question is, how do you get these files on a modern pc if you were crazy enough to write a novel on a vic 20?

I need some help. Can you modify a line by using list? Once you modify the line listed and save will it save with the modification? Thats all ha

I think I had VICWRITER on cartridge for the vic-20, if I remember correctly I wrote a report in 3rd grade in 81-82 with it. I remember my dad had Quick Brown Fox, but I never figured out how to use it.

Awesome to see others coding on the Vic-20 in this day and age. I discovered some of my Vic-20 program code printouts from 1983 or so and will be finishing up those games and releasing them soon.

Is everything okay? I miss your videos.

Maybe a bit of a weird question, but I do like the Font that the C128 (which I assume this is) uses in CPM mode. Do you know if anyone has ever done a OTF/TTF version?

OOhhhhh !!! 27 columns = 54 columns with 4 pixels wide characters !!!

Contrary to common belief, Modula-2 is NOT based on Pascal, but it is a derivative of a language called Mesa, developed at Xerox PARC where Niklaus spend a sabbatical year. Mesa syntax was unorthodox, for example it used square brackets in function calls instead of the usual parentheses. Wirth took Mesa and gave it a Pascal syntax facelift. Thus Modula-2 is based on Mesa, only the syntax looks more like Pascal. If you know Modula-2 and you read the Mesa Language Manual (which can be found online) you will see just how much Modula-2 is Mesa. Wirth actually stated this in his publications, but back then Xerox was rather secretive about Mesa considering it a competitive advantage and thus very few people could check what Mesa was all about and so everybody assumed Wirth was just being humble playing down his work, when actually he didn't, he was being honest. This also explains why Wirth soon abandoned the language and moved on to another language called Oberon which he has been tinkering with for the last 35 years. Modula-2 wasn't really his baby, Pascal and Oberon, those where his own, but Modula-2 was really the work of Xerox PARC.

Welp, time to make one of these for CP/M

Wow, I watched this in the hopes that I was wrong about this editor and maybe I could actually be productive with it. Instead, I now have confirmation on just how ridiculously bad this editor is.

Thanks for this, just the right information i was looking for

Thank you for sharing this otherwise scarce information. Great video.

Man I typed in Speedscript back in high school and used it to hand in some work. When I got a 64 I went to GEOS. But I still miss Speedscript's "transpose" command to fix typos.

This is a great tutorial. However nothing beats the real thing. Back in the day the Vic was my main and only computer. I connected it via a 20 ma loop to an ASR 33 teletype and with the addition of a 40 column display cartridge I had my word processor. The kids marvelled at the beast hammering away in my workshop printing various things such as pictures of the peanuts character snoopy. It was a sad day when I dragged the old girl to the curb. Nothing beats the sound of a real teletype although your rendition is a good reminder of how we computed back in the day. Thanks for the nostalgia.

You do the best VIC-20 video content on the internet!

Apparently, those in the know call ed, "E.D." (pronounced, "ee-dee") and not "Ed".

good evening, I ask if you can make a video on how to create an assembly routine for using the joystick with vic20. thank you

I would like to make the movement of the characters slower, as it is possible to do in assembly, thanks

Was pilot ever used for writing commercial software, i.e. anything other than being used as an educational tool only?

Where there's a ball there's a key!

More than anything this is brilliant font design. I've only ever been able to do 3x3 but I never thought to use the edges of the next letter to increase readability

Fantastic video, I think I'll go with VicWriter

Nice! I've been playing with Logitech Modula-2 on DOS as it's the only one I could find both the manual and media for. I like the language much more than Pascal.
