  1. I'm creating a documentary chronicling the history of pantaloons, dungarees and jeans in the U.S.  Working title is "The Pantsing of America: 250 years of hiney hiding - A rags to breeches story".  By Michael Scott with Dwight Schrute (ghost written by me).

  2. There aren't 2 AY sound chips in the Aquarius. There's a fairly simple sound generator built into the main unit that has a single channel. The Mini-Expander adds one AY chip, providing the 3 channel sounds. The 1541 rom (perhaps BLbasic too) does let you send values to the AY, but I've never dabbled with that myself. Otherwise, machine code is needed to drive the AY. I like the way you are thinking, though! Looking forward to see (hear) what may come.
  3. BTW, My memory is fading a bit, but I think CLS will work to clear the screen while using the 1541 ROM. I need to dig out that original document and scan the whole thing. It's a nice bit of kit.
  4. Depending on how you're calling your subroutines, you may have overflowed the stack? I've attached Aquarius_Extended_Basic.pdfaquarius_extended_basic_manual.pdf so you can see how to use the EDIT command. You always have the option to retype the whole line, otherwise.
  5. I agree that LOGO is a very good way to learn "proper" programming, and that editor is great. With Extended BASIC (including the 1541 version) there is an EDIT command. However, it is not as easy to use as LOGO's.
  6. You can do instant color changes with the SCR command in the 1541 ROM. I highly doubt Aquarius LOGO will allow you to call machine language routines (unless someone perhaps hacks the ROM). It would have been one of the first things axed when the developers were trying to shoehorn the language into the available ROM space. Well, maybe 2nd thing, after they removed the standard Aquarius splash screen and replaced it with simple text.
  7. The 1541 ROM on the Aquaricart has specific commands for reading the controllers. LOGO, sadly does not. It's one of the unfortunate omissions they had to make, it seems. Another one I can think of is there is no way to perform a screen print to the printer. You can print the procedures, but that's about it. 1541.pdf
  8. I wonder what the customer cost would have been for that proprietary "The Window" computer. Would it have been a rental? Was it a rebranded version of an existing platform?
  9. I may be misremembering this quote and its source, but it seems quite apt for this discussion:
  10. Very interesting! That video is great. I love the incongruent button mashing. Is that Balki @ 5:14? Suggestive miming with the joystick @9:19?
  11. Welcome! I'd recommend getting your 7800 modded with more modern video-out options, or purchase one of these to continue your RF video usage. If you're more interested in playing than collecting, you may also want to consider purchasing one of the in-production multi-carts: Concerto DragonFly With one of those, you can download Trebor's Pack, to play a huge list of the original retail 7800 games, hacks, homebrews/demos, and trial versions of for-sale homebrews. Note that the Concerto allows you to load it up with both 2600 ROMS and 7800 ROMS, while the DragonFly is focused on 7800 games only. Of course, you can always buy latest homebrew games on-cart, right here at the Atari Age store.
  12. Absolutely! I love dabbling with the Aquarius. During COVID, I spent many hours goofing around. I made it to the bottom floor of AD&D at each difficulty level, sometimes repeatedly in the same game (looping from 100 to 90). I also found a couple bugs in the game I had never noticed before. I tested several workarounds to the subtraction problem in FinForm. I believe I found one that worked all the time, but it is clunky. I somehow managed to button mash my way into the Command Module menu and play around in there. For the life of me I can't repeat it, but during that session, I was able to do it several times. I took pics of this stuff, and I should create a thread here to share. Keep doing what you're doing!
  13. You will be very disappointed, I'm afraid to say. LOGO would have been a nice intro to procedural programming way back then. Beyond that, particularly the Aquarius version, it wasn't very useful. With the Aquarius graphical limitations, combined with the ROM space limitations imposed on the developers (presumed due to glaring omissions), and RAM, it's very existence is a bit of a miraculous feat. However, to help you out, here's all you should need to accomplish your goal: FD = Forward step RT = Right turn LT = Left Turn BK = Backward step PEN 0 = Pen up PEN 1 = Pen down HOME = return to center screen CS = Clear screen PAPER x (change background color 0 to 15) INK x (Change pen color 0 to 15) TILE x (Change the turtles trail to any of the 256 character codes. To return Turtle track to normal, type TILE 255) POS [x y] (usable screen is 79 across by 59 down. Upper left corner of screen is 0 0) POS ? = returns turtle's current position HD x (change heading of turtle between 0 and 360 degrees. 0=facing due east) HD ? = returns turtle's current heading TP = Turtle print (Move turtle to the place you want the message printed, then type TP 'This is my text ) For fun, I've attached a scan of an old LOGO program I wrote, just to play around with using variables. I found the variable usage clunky, but otherwise appreciate the ability to edit and create procedures. Good luck! ClockFill-LOGO printout.pdf
  14. I checked my AirSea2.bin file, and it is 4k, which explains why it works for me. Is there a 2k version out there?
