        Last night I failed to work out a bug in my game's collision detection routine due to fatigue. I was comparing the screen column of a jeep sprite ( in R8) to the screen column of a tank sprite (in R9). The bug was resolved after eight hours of sleep. The error I made was:

     

    CI    R8,R9        * incorrectly using Compare Immediate

     

    This morning I "fixed" the error by changing the line to read:

     

    C     R8,R9        * why I couldn't resolve this at 1am is anyone's guess

     

       The collision routine ran flawlessly after this simple change.

     

    My question is why didn't the assembler detect this error?

     

    How was I able to incorrectly Compare-Immediate the contents of R8 to "R9"?

    Wow! That looks cool. How haven't I tried this one already? I'm a big fan of Lunar Lander style games. Going to fire this up for Retro-Wednesday after I get done doing all the things a wife makes one do during his vacation. 

     

    Of course my favorite is SCRAA which has Lunar Lander elements....   

    :) << HERE >> :)

     

    While taking every opportunity to shamelessly promote SCRAA I'll probably have to start working PR efforts for my next game. This one features assembly language coding I've picked up thanks to the Assembly thread started here by matthew180. The working title is "ENK" which stands for...

     

    Hint: The title "ENK" is another acronym.

    Just received this info from one of the KansasFest 2020 planners (Peter Neubauer):

     

    A. Registration opens near the end of March 2020.

    B. Rockhurst dorms hold 110-120 people.

    C. The 2019 KansasFest had 88 registrants. Not all stayed in the dorms.

     

    Plenty of room and plenty of time fo save up!

    If someone wanted to sell me a REAL issue of a May 99'er Home Computing (any year) in good condition, I'd pay $5.99, but never for a PDF copy!

    Guy's just trying to make a buck before Christmas. I recently purchased an entire library of several Atari ST magazines in pdf from eBay. Much easier paying a few bucks than tracking them all down and downloading them myself. He's marketing convenience.

    The problem is that my employers are cranks, and I make very little cash as it is.  I cannot afford a very extended trip.

     

    I can probably swing a week, with some leadin and lead out for the drive.  But not airfare, hotel, AND extended vacation.

    You live and eat in the dorms -- no hotels. I believe $350 total is all I paid for the event and five nights billeting in the dorms. Price includes three meals a day!

    Kansas city is close enough for me to attend even!

    One guy came from France. Another from Australia. A few from Canada and at least one from the UK. Several drove from the east coast. I met a few NASA guys from Houston. Several came from the SF Bay Area. Turns out Kansas City is in the middle of the Universe.

    If we are going to do a group meetup at Kansasfest, space is running out.

    Erik,

    Thanks for writing.  The session space and dormitory we’re using at Rockhurst University is nearly full.  Depending on what you have in mind and the size of your group, there might not be enough space.  Would you tell me more about what you want?

    Thanks,
            -Peter

     

       I believe I purchased my tickets for the 2019 event in the spring of 2019? I was early. I'm not aware of KansasFest 2020 tickets being sold right now at all. I'll ask and post my findings. The 2020 event dates are July 21-26. It'd be great to have more TI-99/4 folks there...great!

     

       The Rockhurst University dorm had extra rooms this year as the crowd was about 85. That's at least 25 less than they've had in recent years -- same facility. They are definitely not experiencing peak attendance these days. This reply seems oddly short...as they were open to a TI-99/4A presentation for 2020. I mentioned it on their post attendance feedback form. Peter's reply here is more cautious than definitive. 

     

    EDIT: Tickets for the 2020 event won't even go on sale until January 2020. How's the space nearly full? 

     

       Reading between the lines I'd say he's being cautious. They have a great Apple // event and probably don't want it turned into anything too non-Apple. I'd like to offer encouragement on this plan because everyone there (I met and talked with dozens) seemed interested when I mentioned I was a "TI-99/4 guy."

     

       I ran into retro Mac people as well as a big time CoCo programmer. Even a few Atari-800 guys...lots of non-Apple specific podcasters too: Jason Scott (archive.org), Kevin Savitz (Antic Podcast), Joe's Computer Museum on YouTube, etc.

     

       The tickets are always sold on a first come first serve basis. I'm not aware of any annual reservations. The 2019 event was not sold out to my knowledge. I did notice a few empty looking dorms.

     

       They do seem to have a very busy presentation/workshop schedule. It's my understanding they are still building the schedule for 2020 and will continue to do so for months -- maybe 6 more months? There we're random events each evening. More than enough time to slip in some daily TI-99/4 tomfoolery. 

     

       "There might not be enough space" has me thinking this is an inaccurate statement.

     

       Here's how it works guys: All the interested players purchase tickets to KansasFest 2020 and we meet up at the event! Before we go we offer to do a presentation. We can be a special interest group within a special interest group. The event is awesome and open to anyone interested. I agree with FarmerPotato that this would be an excellent venue to meet up with like-minded TI-99/4 fans....whom also have curiosity regarding the Apple // and all things retro.

     

       It's the ultimate retro computing kitchen hall pass. Think the film OLD SCHOOL but even nerdier. Cost was far less than one would expect to pay to stay in a Motel-6. The dorms are comfortable and the food was good. It's an awesome value.

    Numbers per amount of work on a project.

    I could do it but with only 8 people that care vs many more using RXB seemed no point in doing it.

    In the TI-99/4 community eight people just may constitute a majority. ;)

    At one time I was going to jump into TI Writer GPL and fix what I could find and add features, but FW just makes that pointless.

    Since when did having a point stop any of us from doing anything TI related? ;)

    ... especially since most of the people who really want the items and are willing to pay his prices already have them now... 

       Back in early 1997 Zach told me he had "so much TI stuff I don't even know what's in there." He added, "I wish I had someone knowledgable on TI to come visit Waterloo to help me figure out what all I have." He never offered payment for such a trip so I ignored his statement. My take away from that conversation was that he had very little idea of what it was he was selling. He asked me what an Assembler/Editor was for, etc. The final thing he said that made me want to go up there and snoop around was, "After a few years of selling I've only sold maybe 5% of everything TI related in the lot." Wow. Safe to say there's a lot of NOS remaining.

    My big question is how did all of that hardware end up in such a remote location as Waterloo, Iowa? 
     

    Dhines was some regional distribution center apparently. How? 
     

    Why didn’t the original owner liquidate it to then file for losses on his taxes? 
     

    It’s an amazing haul for Zach. Good for him! People get in a huff over his prices but he’s simply selling items at what he can get.


    I paid $49 for a NOS E/A package which was Unobtanium elsewhere. They’re down to $39 now. Was kind of fun to open a pristine 1980s sealed package.

     

    He probably sold the NOS PEBs for less than he could have.
