It's already 5 years, but here we are... I started with learning Atari BASIC and Assembly just a few days ago. Thanks to your videos I am progressing like a champ I was struggling with how to start assembly code from BASIC {I am a Commodore guy and there it is, e.g. SYS 4864} Did not work with ATARI, but now i see it here, USR is to be used X=USR(4864) I am emulating ATARI-800XL, but it seem that most memory locations are the same as on 130XE

Dude, you rock!

haha 2019 .. guess what is coming in 2020

An 800XE GS was mine!

cool, is there a source where i can look up code and adopt?

When I passed the fourth grade and got all As & Bs in the final grading period, I received the Atari 800 XL. In addition to the computer, I had the Atari 1010 Tape Drive and the 1050 Disk Drive. The printer I had was made by Radio Shack, but there was an adapter that made it compatible. The one thing that was convenient about the accessories was that you could daisy-chain them. On a different token, I did some reading and learned how to do some programming via trial and error. I created a game called “Ski Trek.” You were a flashing letter “H” and you used the B & N keys to move left and right. You were given the impression that you were going downhill because up-arrows, which were the trees, were moving from the bottom of the screen toward the top in a zigzag motion. When you ran into a tree, the word crash would appear in the middle of the screen and the total number of feet that you traveled would appear right below.

How about an adapter for connecting a Jaguar controller with an 8 bit computer or as a 5200 controller ?

peek(88)+peek(89)*256

The first 3 lines mean that you have the option to buy an object with cost of US$ 3000

Does it work with 65XE?

No way this is the best game

This shows how to open it. Do know that there is most probably a sticker on top of the fourth screw with a removing voids warranty message.

Muy agradecido por el video, voy a seguir estudiando por acá. Un abrazo

1 correction you use mini speedy 1050 not the plus or super. You say with copy disc its in the buffer from mini speedy but is not true. Only with mini super speedy has 256kb for buffer. Solder a switch on it where os standing when open copy program when closed bibi dos. Firmware 1.7 for use with ntsc. I have mini speedy 1050 round 1991/92 i have bibidos and this copy program on it. But old firmware 1.3 i know 1.4 was the latest on super speedy 1050. I have mega speedy 1050 all upgrade drives on it. Happy 1050 etc. I like the videos....🎉🎉🎉🎉🎉 My 1050 are all tandon. Rom or eeprom(on your video) upper side white ristors are the switches for eeprom or normal rom. I have 1 oldest tandon. Before the great heat plate backside 1050 has errors on 12v 5v it get to hot they where soldered with cables to the heatplate fix. Later they have tem located to the back. But the best upgrade is mega speedy all upgrades. But bitwrite not or someone can add it to. Or switch back to old mode. For copy protection speed goes low on the speedy happy etc or unhappy can don by software. Or a switch slowmode.

Since you're talking about Antic Podcast you can check out the interview with Kathleen O'Brian (#22, 2015) about Atari Assembler and Paul Laughton (#126, 2016) about Atari Basic. And finally with of Clinton Parker (#111,2015) of ACTION! fame.

It is a shame that Atari programming was often the subject of advanced books like Compute's series, whereas the Commodore C64 manuals that came with the machine described sprites and colour map.

Great video! Where can i found the 3D files of the case?

Do you use any string packing of Atari Assembler? That's a great way to put little assembler code in the BASIC programs.

Cool, I’d like to start from very beginning in asm. Where I can get a proper manual that starts from zero…? Love your channel

So many memories. Used to run BBCS on 800xl (moved it over to 130xe with a piggy-back 576k RAM upgrade (right around 1987), SpartaDos, Happy1050s (fixed the disk sector issue), ATR8k, and my last work, using the ATR to connect a couple of ULCMicroNet devices to network up two TRS-80 Model IIs to provide a multi-user BBS (in pascal) on the Atari. Click Bang all night as the 8" heads on the Shugart drives. Ahhh memories...... :)

Not sure if anyone here can provide any help, but my 130xe has completely cut out the video, i have no av output at all. Anyone have any suggestions?

14:19 A question: in Line 220 you could have just used normal ADD instead of ADC, right ? If you did so then you wouldn't even need Line 190 CLC, isn't that right ?

> GET SWORD YOU ARE SWORDED

-Good video, really liked it. Have to go back to the game programs I wrote on the ARARI 800 XL and the 800 XE to see how I wrote the load. I wrote a full-length Ultima type game in the middle 80"s Made me curious. Thank you.

Did you have to write what that string does in assembly first in order to make it do what it does? Or is the string the equivalent of making the background boarder colors different? Also how did you make that machine language string specifically do what it does? Thank you in advance i am a novice in atari basic but im trying to learn new things!

Hi, I’m interested in doing this on my Atari 65XE because the graphics mode is better. How can I do it? Thank you for your attention! Thanks for a response!” 😊 ps. great tutorial!

Every Antic or ANALOG magazine I opened, I drooled over the MAC/65 ad but alas, as a kid, I couldn't afford the $99

I remember typing these op-codes from ANALOG magazine. Fortunately they included checksums.

i remember i was programming in basic as a 8 year old child and playing with graphics and was wondering how to make graphics fast so as in the games :) unfortunately i had no books or anyone who could show me this stuff back then

Is this germane to the Atari 400 mini?

Man, I knew and used all this stuff as a 14/15 year old in the 80s. Display list interupts, player missile graphics, collision detection, joystick movement, sound, animation, character sets etc. I was self taught by combining and experimenting with the mini programs for each aspect of programming found in books and magazines. Can't believe I knew all that back then. Can't remember much of it now. But I'm interested in learning it all over again as I've just bought a 400 mini which is programmable. I still have the original 400, modded with 48k and a proper keyboard, but the dedicated cassette loader is broken, and who has a TV these days that can accept the old RF signal and connection? Great series here, thanks. Will be watching them all with great interest.

OSS: You might try Action! A fast compiled language in a super cart along with the editor.

My S-Drive Max doe not have the power switch, so I need external power. I've been using the USB cable connected to a battery to power it.

Hey, my Atari 130XE gives picture that goes up/down rapidly and also flickering mess. There is no repair man for ancient computers here in Serbia (heck, you can hardly find proper old school electrician). I am amateur PC configurator and I have soldered lots of electronics (mostly old Roland electric drum parts). Any help?

"Atari Newsletter And Lots Of Games" is how A.N.A.L.O.G. Computing magazine explained the name "Analog" for a magazine about digital Atari Home Computers. It was one of the very best of the Atari magazines. Compute was almost as good, but it tried to cover all home computer systems. Atari 8K BASIC was notoriously slow because it treated ALL numbers as floating point numbers, including line numbers! Try starting a line in BASIC with 1.24E3. It works! But there was a bug in the floating point routine that made it run very slow. This forced me (us?) to get into 6502 Assembly Language very quickly. The fact that ATASCII can represent all 256 8-bit binary values meant machine code could be directly represented in "text" strings. Add to that that BASIC strings could be defined up to 32K long, and the ADR function that would give the address of the start of a BASIC string. The USR function would call a machine language program at a specified address and store any return parameter from the machine language routine in the variable associated with the USR function. We often used this process to create integer math functions that would run faster than the usual math functions in BASIC. It was also a convenient way to access some of the more advanced graphics of our Atari computers.

Great vids!

The Atari800 emulator for the Mac, Atari800MacX, will also allow you to create large hard drive images. Atari DOS 2.5 does NOT support double-density disk formats. It only supports the single and "enhanced" density supported by the stock Atari 1050 disk drive. I had a 1050 upgraded with the Happy Disk ROM that allows it to use Happy's "Warp Speed" data transfer as well as true double density. But you'll have to use a third-party DOS such as Happy's Warp OS, MyDOS, or Sparta DOS to use the double-density disk format. I got a copy of Sparta DOS with the bootleg Happy Drive ROM upgrade I got.

Actually, you only left one space before the CLC so you DIDN'T clear the carry bit, it's a label, like LOOP is. Also, the END pseudo op is a label as well for the same reason. Line 30 was flagged as an error bexause #0 is not a proper op code. CLC is a perfectly proper label so the assembler didn't complain.

cool, nice introduction .. i played with this in the 80's but never really did figure out collisions ... from looking at your code ... does that reserve the memory location every time you run it ... such that after so many runs you have sucked up all the memory ... :) I am guessing that because I would guess the garbage would be gone on successive runs ... unless you slide down the memory map with every run

Hello, thank you very much for the great instructions about ASM language in Atari. I am really interested in. I have Atari 800xl, and typed the same code as you showed, but receiving the error messages when I assembling with asm command. The error messages: 10 *=$2000 ***error 6 20 LDX #$FF ***error 6 . . What can be the issue? Is the code for Atari ST, so not compatible for 800xl? Thank you for your support, Regards

Seems to me you had a fully working system but one bad floppy disk. The screen position could easily have been fixed by adjusting the rings on the CRT. Resoldering, recapping and even replacing ICs on the AV board was not necessary.

Bruce Lee Koffie is the best

OSS? They made the Action! language (an orange cartridge). That is where I learned to program. It was like a combination of Pascal & C. You could also inject some machine code bytes. Atari 8-bit got me started as a teenager and into college, where Atari 1040 ST got me the rest of the way through college and my first fulltime programming job (on for Atari hardware of course, but my personal projects helped to secure my first job).

I had an 800xl when I was a kid. I wish I would have kept it.

Finally, ever since 1986 or so, I get to try Mac/65. Thanks for this video explaining how to use Mac/65 and DDT. That was great fun!

Had one of these. Great times with it.

This was my first computer 🖥️

I had my first Atari 65XE computer only in 1988, because in Poland there was still communism, and in 1989 it collapsed, so in 1990 I already had an Amiga 500. In Poland, games and various extensions for this computer are still being developed. th-cam.com/video/zRGpT-Kjxs8/w-d-xo.html
