    the school (as did many) ate the Apple.

    In Ontario (a large, rich province in Canada), a couple of PETS were in the math classrooms in the early 80 when I was in grade 7. In New Brunswick (a smaller economically challenges province), I got to use PETS from 1984-1987.  The main lab had several pets chained to one disk drive - most likely the cheapest option. There were a couple of single machines, the versions I don't remember save the SuperPet that help make me a "super" programmer. 🤓

    My understanding is that Comodore pushed heavily into the school systems in Canada. 

  2. I tried to load the program on the R38 emulator and it failed with a "?Device not present error in 41020". I had placed all the files in the same directory that I run the emulator out of.

    I then placed it on a SD card image where it ran without issue. Perhaps updating the entry in community downloads to 

    The one small bug that I found is when you select save enter some text then delete it the right border character moves left. Its just cosmetic and I think few will encounter it, so I'd rate it as a very low bug to attempt to fix.

    The 6809 was a wonderful processor that I have worked with. With the (indirectly with the SuperPet SP9000) and with coding the chip directly. I wish it took off. Really.

    My computer knowledge really took off in grade 12 when the typing teacher removed me from the regular class (I think my knowledge and ability really challenged her.) I was given a SuperPet, disk drive and the complete set of Waterloo languages with manuals  to work in another room (so I wouldn't be disruptive to the main class or teacher.)  Structured Basic, Pascal and Fortran were real joys, APL was just neat but my background math knowledge was lacking. Assembler on the 6809 and 6502 interested me; I should have done more. Cobol didn't make sense then (or now) - that experience suggested I avoid working it for Y2K. 

    From reading about the evolution of the Waterloo languages, there must have been a couple of engineering/CS students who had exposure at the university level. Hopefully they benefited from the experience.  I did!

  4. Welcome! 

    There are many good leads for learning assembly here while waiting for the first phase to ship. Also consider other higher level languages that are available.

    As for Jumpman, I'm unaware of any options yet for the x16. There are some other great games on the X16 now that you might like.

    Give me PCBoard or give me death. Metaphorical death to be clear.

    Usenet forever, as well as RSS, plus two tin cans with string!

    It looks like they made the change last night, while those of us in the US slept.

    Thanks for the update, glad it went painlessly well. I'm not seeing any issues.

    Some of us on the North American content are night owls, or at least insomniacs. I was up but stayed away from the keyboard last night. If I could sleep, I'd dream of sleeping a solid 8 hours uninterrupted 😴


    Somehow the above sounds like an infinite loop of cause and (d)effect. 🤔

    I bought an SN76477 from Radio Shack in the 80s.  I wasn't up to the challenge.  But it was cool.

    I've got a few of AY3-891xA chips in a very mixed collection of IC's from the 80s. Someday I'll get to them, but I like the 556/7411 circuit above as getting it going as it doesn't involve programming 🙂 .  The Vic 20 sound chip was understandable for a 80's teenager;  audio programming on the X16 seems to be a much large area given the number of options it has.  I'll be happy with whatever the x16 ships with, given my lack of musical talent. That would be my dream combination, since I really don't know any better. 


  8. I noticed that hoovering over a poster's name now brings a well laid out dialog/pop-up rather than a scrambled mess. The dialog isn't 100% but it's readable & usable.


    Clicking the name goes to a informative page about that user. 


    Thanks to the admins who've addressed this issue! These tweaks make the forum/community better.

    I also have the schematic above (Space Invaders STEP sound)

    I'm a little lost - the schematic you posted was a bitmap with no SN76477 but your recent picture shows one in it. I've skimmed https://en.wikipedia.org/wiki/Texas_Instruments_SN76477 to get a better understanding of this circuit.

    Any chance of posting a schematic of  what you have built? Or is that mute because the chip is no longer being made as far as I can tell.


  10. I'd like to suggest an online X16 conference via one of the many video chat services on the net. There are many great community members I'd like to meet online. Also it would provide something new for the community that should help build it. Finally, it will kill some time while waiting for the X16

  11. I feel some of the success and longevity of this site is that its specific to the X16. That has built community here that will keep the site going until the x16 ships (someday) and beyond. I do like some expanding of the chat areas to accommodate other topics since the members here are interesting and respectful. Those additions will allow those members who aren't interested to read it to keep just to the X16 areas while those who want can go on the new areas to post.  

    I do feel that with the delayed X16 that some of the freshness and enthusiasm for the project has peaked and now most here are waiting patiently. Others may have put things on hold till hardware ships. Certainly having the forum keep people interested and connected is the goal.

    I'll end with a little humour  - I tell my wife every morning that I go online to read the whole internet, since I didn't finish scanning it the day before. 🙂 Once the X16 ships the internet won't be as interesting and I'll spend less time on it.

  12. I've heard ME stood for "Major Error." 😝 

    Microsoft has a long history of creating new looks & features for Windows which keeps the industry having to redo software, keep retraining the users and keeping tech support people busy. Imaging all the time saved if they just got it right the first time.

    I'd debate that sums up most of the industry. Had everyone just stuck with 8 bits we're all be in a much better state. 

    I would have just politely not taken the job. Not sure if that would be foresight or hindsight.  I'd hold out to lead the Encarta team

  13. Hi,

    Glad to hear you've found the community and are enjoying the fun!  

     You can find the input command documented here - https://www.c64-wiki.com/wiki/INPUT

       Here's a simple example that demonstrates exiting a loop programatically.

    10 CLS
    20 A$=""
    40 IF A$ ="" THEN 70
    50 PRINT "YOU TYPED " A$
    60 GOTO 20
    70 ? "PROGRAM END"
    99 END

    A feature in the X16 basic is the OLD command - which restores the last program typed in memory after a reset. That should help you if you are forced to reset the computer and works in the online emulator https://www.commanderx16.com/emulator/x16emu.html or a local one.

    It appears that the ESC or Ctrl-c combinations does not exit the INPUT functions as you've discovered - https://github.com/commanderx16/x16-emulator/blob/master/README.md#functions-while-running. I don't have a real C64 to test if it works on a physical device; my VIC-20s are currently in storage. 😞

    Hopefully this is the info you are looking for. If not please ask - I and others are willing to help.

  14. I'm glad there are people to step up and take managing this community on, and there is time to figure out a way forward. 

    To me the site IS the product at the moment. While we patently wait for a shipping X16 there is so much here to enjoy:

    •  the forum with all its users who have posted from the technical to the social (with their own wit, insight and opinions)
    • the library of software available, and
    • the ability to run a web emulator.

    I believe the majority here will gladly become consumers because they are part of the community. One the hardware ships I hope there is an explosion of more free software here, rather than spread far and wide on the interweb.

     Finally, this site has the best forum implementation I've ever seen. Kudos to  those who built it,  those who will manage this community. and those who contribute content.

    Thanks 🙂

    The part about my childhood and it "suffering" was jokingly meant 🙂 hope that came across.

    At the time I wasn't very interested in computers or gaming. Spent most of the time in the Library.

    The tone came across, but I played with it as a mono 286 with text only seemed painful to me. That being said, I did have one as a spare machine which I loaned to friend in 1st year of tech school. it allowed him to work in his studio apartment (box) rather than having to work in the open labs with all the other students. Compared to my 386SX 16 and 4 megs of memory, 100 MB HD with a VGA card, Sound Blaster and a large CRT it was suffering to me, but better than nothing for him. 

    Based on Hard Hat Mack (https://archive.org/details/wozaday_Hard_Hat_Mack) it seems that your fathers 286 had a CGA card in it. 

    I had the joy of playing the original Zork on a terminal via a 300 baud modem connected to a mini in the early 80s. 

    When the pandemic hit, the local library closed for a while, then gradually opened up again in various stages. It was the first thing I missed when COVID countermeasures started.


  16. Welcome!

    My childhood "suffered" a bit from me not owning any 8/16bit computers or consoles. All we had was my fathers work PC (286)

    No one knew what would happen to the kids who grew up in the 80's with these "new" home computers. The 90's it was what was going to happen with the Nintendo kids. These days it might be what will happen with the kid who's used an iPad even before they could talk? 

    A 286 with a mono monitor and a text MDA video was kind of the standard work PC (I assume that's what it was.) It did Lotus 123 and Wordperfect 5.2 acceptably.  Perhaps not much attraction for youth either then or now. However, it lead you to a career in the field and to here wishing for an x16. A common story.

    Oh boy... bad or outdated documentation isn't just the province of spaghetti coders or self-publishing enthusiasts. It is even practiced by a certain IT multinational based in Redmond in the US state of Washington (in other words, "they who must not be named"🥵)

    Spaghetti authors/publishers basically throw the product against a wall, and see what sticks. If it sells then it got 'updated' when the next version came out. The star that I won't name had this written about him: (somewhat edited to attempt to avoid identifying the person.)




    "This author  is called "one of the world's foremost authors of books about programming" by a programming  magazine. He is featured as one of the rock star programmers in Ed Burns' book Secrets of the Rock Star Programmers.  This foremost writer's books have sold in the millions, worldwide.

    His books have a reputation for being riddled with errors. Their technical accuracy has been challenged by many reviewers, including the ISO committee members & numerous  reviewers from a programming association.

    Other reviewers have been more positive, with one  reviewer saying about his book that the writer "has learnt something, not enough to receive positive acclaim but enough to remove the 'positively detrimental' epithet".


    He claims he was a member of the original ANSI committee that standardized a language in 198X, and the ANSI/ISO committees that updated that standard in 1990’s.  Other members of the ANSI committee have drawn his presence in the committee and the quality of his committee efforts into question.

    Spaghetti coders who write spaghetti documentation seem to be an "un special" case. I think we've all been subject to them; one was in my formal school as an instructor. 😞

    In the X16 community I've found people in general document things reasonably well. Perhaps because there is little money or fame, but more so I feel that they do it as a labour of love. To me, it captures the same spirit as in 1980s computer clubs I was involved in, making this project even more "retro."


    PS- Thanks for providing a detailed set of examples Maico.

    General question/concern; was it not the idea with this forum to get the announcements and communication from David & Co here first? 

    I'm not sure if first was one of the goals. Given the number of platforms out there one would hope this would be the primary one, as I feel its a better community than FB in terms of content and structure. I read the thread on FB and things seemed to turn ugly quickly.  😞

    Given that announcement , it's good to get an update on the project even though it is stalled and will have chip supply issues too. 

    PS - His last here visit according to the forum SW was Oct 24th, so perhaps this is appropriate:
