  1. I did a search for 6809 Disassemblers and a whole bunch (5-6?) popped up. Can anyone vouch for one of them? I have a BIN of a 32k CoCo game (Time Bandit) that I want to disassemble to not only figure out how it works but also pick up some 6809 along the way. In a perfect world the disassembly would easily be reassembled; but more important than that is examining all the object/map data. If possible this would be compatible with Windows 10.
  2. I tried CoCoDisk-0.7 and after installing the requisite fdraw it still didn't work. Also, I tried wimgtool but was told it couldn't recognize the DSK format. I don't know if Windows 10 is the culprit but that's what I'm using. Thanks for the link. I think it's working great now! I think I may need to build a Linux box as most of these open source projects are written for that.
  3. Sorry, I should have been more specific. This is for the TRS-80 Color Computer.
  4. I'm trying to remove a single .BIN program from a .DSK disk image however I can't find any utilities that will work properly. Can anyone lend a hand? At the end of the day I want to take said image and disassemble it on the PC.
  5. I think as a first project I'm going to try and convert this over to TF. First obviously I need to learn TF which I am currently doing. But also, I'm going to put this game through a disassembler to get the 6809 code and comment it up a bit to figure out how it crams all those screens into 32k. Probably too aggressive to finish this year but may be ready to show off in 2018.
  6. I downloaded Classic99 last night and started messing with Forth. Very interesting! Although I agree using a PC Editor to enter code and then copy/paste is probably a good way to go - I think in the beginning it's better to stick to interactive mode to get a feel for the language. I suppose the hardest part of Forth for someone like myself with no experience is how you create a full application with it. I understand the need to "pay your dues" with learning how the stack works; but taking all of that and building an application that uses words, takes input, etc. is the baffling part to me right now. I'm sure in time it will come.
  7. I forgot to ask - do you see anything in that game requiring a F18A?
  8. I don't know how many people out there are like me but I'm interested in getting involved with the TI/99/4A but have no idea what hardware to buy or what to look for when buying hardware. In the Developer sub-forum there is a pinned topic for languages but I've seen nothing (yet) for hardware. So can someone help me out? I'm looking at this purely for Turbo Forth development but may include some assembly language if needed. So here is what I "think" I need: A TV/Monitor capable of taking Composite. TI/99/4A computer w/ Composite and Power cables. 32K "side upgrade" - I think it's a card that sits on the side. A TurboForth cartridge. Things I need help with: Monitor: Any recommendations on something thin and around 17-19" (not too big.) Data storage: What is the best medium for saving the programs? And how could I get those on the PC to pass on the Internet? Joysticks: I hear the originals are not ... that good. Are there options for connecting Atari or Sega ones? External keyboard: Blasphemy? Is there a way to connect an external PS/2 keyboard or such? I see pictures of a big box which I guess is for expansion I would really like to avoid that if possible and keep the setup as lean as possible. Anything to look out for when buying things from ebay?
  9. I am from the US. I'm less hesitant to buy TI hardware as the prices are lower, systems are more plentiful, and they seem to be more reliable than say a Commodore 64. Do you have any favorite Forth books for getting started? Do you have a favorite emulator / editor?
  10. I don't want to waste their time as they are probably pricy but has anyone checked out Cloud 9 for refurbed CoCo 3's?
  11. I would like to see a video on the basics of making a video game. It doesn't need to be very complex - even something like Pong would do. But basically how you build the sprites and then the basic engine of moving the ball and taking inputs. So I can give a little context for my situation I had grown up with the TRS-80 Color Computer and recently decided to get back into it; however for that system because of the high prices of everything I'm thinking of sticking with Emulators for that and purchasing the physical TI/99/4A hardware instead since (currently) it seems more reasonable. I just need time to figure out all of what I need to buy. I've been keeping an eye on Ebay for TurboForth cartridges but haven't seen any recently. My primary motivation would be for learning Forth and developing games for personal enrichment - not necessarily to use the TI as a game playing device if that makes any sense.
  12. Do you think TurboForth could handle something like this? This is a TRS-80 CoCo game:
  13. I just had a thought this morning. The prices for Retro stuff is getting out of hand (for me.) But can you imagine for a moment if emulation didn't exist at all - and the only way to play this stuff is through owning the physical items? Suddenly everything would become bars of gold!
  14. Would this have been possible in Turbo Forth?
  15. After a few years of watching others bask in glory I think I want to try my hand at a CoCo project to show off at the next CoCo fest. The thing is I have zero hardware and the prices are getting out of hand - not just CoCo - but most other Vintage systems as well. The worst I've seen so far is the Atari Falcon which goes for $$$ cha-ching $$$. Is this blasphemy?
