  1. This looks interesting over at the Atari 8-bit pages: Uses WiFi to boot off of disk images on a LAN or the internet. Explained in podcast: https://ataripodcast.libsyn.com/antic-episode-63-sillyventure-and-fujinet Will the TI TIPi gurus please compare and contrast these projects?
  2. I recently picked up an Atari 1200xl with one broken key switch stem. The previous owner attempted to glue it together. The top of the stem is stuck inside the keycap, with the bottom half remaining attached to the keyboard. Any ideas on where to get a new key switch replacement? Recently, I replaced the ALPs key switch on an Apple //gs keyboard. Wondering if the Atari 1200xl has removable key switches?
  3. Hey @retroclouds , When I load the file MBX_S into Classic99 by @Tursi all I get is the "ONE MOMENT PLEASE..." deal -- forever. Strange how this was produced with little to no documentation. Am I missing something here? The readme.txt is so encouraging. I wish I had these files in a .pdf or .txt file for examination. Loading into E/A removes control characters so all I see with the editor is scrambled code. Looks like the Emergency Action Messages I used to decode back in SAC. Again, I can not make out any documentation?? Bob has apparently supplied the keys to the kingdom of MBX yet I find myself pounding on the front door because it wont open. Help!
  4. Jan 2020 Phoenix VAST Meetup included a survey of the Tutor Multi-Carts. @sparkdrummer and the entire VAST community were in attendance — 100% participation. May need to make a YouTube best of video for these carts. @retroclouds Pitfall was amazing and @jedimatt42’s Sega Genesis Tomy Tutor controller mod proved to best the native Tomy joystick.

  6. This worked for me Matt! Thanks!
  7. Noticing the article about five Atarisoft titles being released in Sep 1983. This was well after the locked-out cost reduction “QI” model was being produced. I suppose Atarisoft had nothing to lose at this point marketing games to the more common non-QI models?
  8. Family computing magazine says the Atari Proline (known as Pain-Line) is an improved Atari controller. Especially noting the side buttons? Ha! Instantly invalidates the entire article.

  10. T40XB? Is this a 40-column text XB?
  11. I’ll click on that question mark to see if I can figure it out before resorting to RTFM. :)
  12. That’ll come in handy — thank you! I’m probably under-utilizing the debug tools with Classic99. I’ve figured out how to watch specific VDP and CPU memory locations, monitor the Register space, and watch the status bits, program counter and other obvious stuff, which is extremely useful — fun. Setting breakpoints in Classic99 is something I’d like to use. It’s not so obvious. Maybe I need to examine the readme.txt or something?
  13. Thanks PeteE. Upon your recommendation I’m using the IntelliJ IDEA 2017.1.5 editor with xtd99 IntelliJ Plugin, which provides these red squiggles yet I’ve somehow toggled this error correction option off? It no longer provides these visual queues. Maybe an update turned that off? Damn....now I have to get that working again. I’m using plugin version 1.5.1 updated for IDEA 15.
  14. Next Question: How do you guys manage an assembly program’s size? Since I don’t fully understand how the assembler parcels out memory, other than with the specific in-code declarations I assign. BASIC has warnings for low memory and a command to let you know how much memory is available. What’s the quick and dirty for for doing this with an assembly program under say EA3 option? My current project produces an object code file which Ti99Dir says is of Size 251; disk size I’m using is 720 sectors, used is 254 sectors; free is 466. Any tricks in Classic99 I can use to check program size or mem available once loaded? Any pitfalls to avoid or or think about as program size inflates?
  15. I see now.... C R8,R9 * the assembler is looking for registers so this is the same as... C 8,9 * I personally dislike referencing registers here without the ‘R’ simply for beginner readability * so I always use the ‘R’ as a form of better documenting my code CI R8,R9 * since the assembler is looking for a register and an immediate, it sees CI R8,9 I doubt any coder would ever intentionally wish to place an ‘R’ in front of an immediate constant in this way. This ‘typo’ of mine took a while to figure out because as an assembly beginner it was difficult to see without a warning. Thanks for the clarification guys.
