  1. I'm curious what the status of this project is. Any updates?
  2. Filled polygons weren't really a thing in the 80s. I tried looking up when the filled polygon algorithms were first created, but had no luck. Wireframe was clearly the thing in the 80s
  3. Like the Joust port, this requires a CoCo 3 with expanded memory to fit all the sound samples.
  4. This was ported by Glen Hewlett, the guy that also ported Joust, and PacMan from the arcade code. He was interviewed on yesterday's episode of CoCoTalk!
  5. You can download it from here: https://github.com/nowhereman999/Defender_CoCo3 A video: https://youtu.be/jLdAvNj8HNI
  6. You can try here: https://colorcomputerarchive.com/repo/Documents/Magazines/
  7. There were many hardware related articles in various color computer magazines, but I'm not aware of any recent plans being publicly posted
  8. Looks like an early CoCo 2 given the fact that it has the "melted" keyboard. Some of your cables look like they are for an oscilloscope. The one thing this machine doesn't have that you will need is extended color basic. It's required for disk basic. Not sure if you can program that onto something like the CoCo SDC or if it still has to go internally.
  9. I bought a sonic game because so many people are fans. Played about 5 minutes.
  10. The moving through a crowd stuff, having to go back and forth across town... really tedious stuff that ruins what is otherwise a pretty good game
  11. Just an FYI, the 6803 & 6809 have A & B registers (accumulators) as well as an exclusive or, but sadly EOR doesn't work between A & B registers like the code shown. You have to LDA val_A, EORA val_B, STA val_B, etc...
  12. If you want to play a specific game, it may only be on one machine, so I'm not sure there is a best answer here. Rainbow Magazine for the Tandy CoCo ran adventure contests, and they published books/tapes filled with games you won't find on any other machine. Tandy also had some exclusives including some graphic adventures you won't find elsewhere. I'm sure there are similar examples for just about every other machine. The Magnetic Scrolls adventures weren't on 8 bit machines. The virtual machine was basically a stripped down 68000 from what I've read. Not very practical to implement on an 8 bit at the time, but it has been done more recently. The graphics were best on the Amiga which also had infocom adventures, but you loose a lot of early 8 bit adventures. Personally, the added graphics, and better text parsers on those games make them a bit more enjoyable.
  13. Nah, I have to work when there's work, and I'll have work to do then.
