  1. Yes, I think so, for DOS loads especially. I've thought about this. What's needed is a 'shared disk' over the network. One atari acts as a disk server and contains disk images for bootable environments and a server program that accepts incoming disk requests. The client atari would have a hook in DOS init that loaded the handler (from ROM or something on the cart or PBI/ECI) and would hack the startup such that all low level disk calls that go to the disk drive D1: instead get vectored out through the handler to the server as just get/put disk sectors and stuff. As far as the client atari would know it would have a boot disk locally as per normal. Doing an OS load would be harder because you'd need an active handler of some sort on the client machine. Maybe a small mini-OS could boot from the PBI or something and load a real OS from the handler.
  2. So, this sounds like a good idea. Since it is not related at all to the original dragoncart, I would prefer that the name be different. The original was a 5v cs8900a chip and support glue attached to a cartridge, without it's own internal IP stack. From a quick thread skim, I'm not sure if the item being discussed is a cartridge, or an ECI/PBI, or maybe it's both. I think that the ECI/PBI is a better implementation than the cartridge, but if the cartridge has a pass through then I think it's kind of moot but I'd still prefer the ECI/PBI. Please put me down for 2 of either the PBI/ECI (if available) or 2 of the carts. Actually, I'll probably buy 2 of both, but lets start with what's being discussed. As far as software goes, I do have a stack written as a device handler using the I: device and driven by VBI, so it's accessible from any language that can use CIO calls. It supports a stack with ARP/ICMP/BOOTP/DNS/UDP, but the TCP part was about 1/3 done when I ran out of gas. It's freely available to anyone who is interested. Using a chip with it's own stack will change things greatly, but it's a good proof of concept for using an interrupt-driven CIO handler. It will probably be much easier using the new chip. For gaming, what you typically need is a really fast UDP implementation and so the makers should concentrate of the speed of mioving things off of the chip and into memory. 1. davidcalgary29 - 1 cart 2. xrbrevin - 1 cart 3. skriegel - 2 carts 4.

  3. OMG what a score! Congrats. That bit 3 is extremely rare. Does it work?
  4. Be aware that this is not an easy goal, even if you already have programming experience. Aside from Karl's question above - Have you searched for threads about 'how to program 2600' here? There are many such threads. It's too big of a subject area to just say 'please help'. There are also other online resources about programming for the 2600.
  5. I didn't care for it, and I don't think it will be particularly successful. Bethesda doesn't seem to really understand what most people (I think) loved about the earlier fallouts. Even fallout 4, which I liked well enough but didn't love, suffered from it. Here's the deal - I don't want to build things. I don't want to play civ. I don't want fancy decorations or to play dress-up with armor colors or hair/face/body editing. I don't want bouncy colorful happy-time emoticons. I don't want to have to deal with some 12 year old trying to kill me or even just having to listen to him or have him wave and show me stupid emoticons. I don't want to have to cook and/or make routine things. I don't want an open-world multiplayer Farmville. I don't want a battle-royal that keeps replaying in a cartoon-style world. What I DO want is story immersion, yet to still have open-world freedom. I want to shoot naughty things and blow lots of things up.I want to feel like the decisions I make make a real difference in the story line. I want to have goals to help people that mean something. I want good plots and lots of good side quests. I want interaction with NPCs, including the decision to just shoot them and to experience the consequences thereof. I want a dirty, gritty world that looks like a nuclear strategic war happened. I want story continuity. I want to be pressed hard to scavenge and explore for survival. So,as a lot of people like me feel, New Vegas was the pinnacle of Fallout greatness. Fallout 4 was OK, but they had started the process of dropping things like faction systems and skill advancements. The story lines were actually pretty good, but really it totally did not matter what you did in NPC conversations other than maybe shorten steps via charisma checks. Faction had no real meaning other than at the very highest story level. It had a good weapon and engagement system, but they dropped some mechanics around weapon repair, and yet oddly kept them for power armor. I hated that so much work went into the stupid 'let's build outposts and beds and paintings and walls and pictures and lets have to deal with directing a bunch of mindless NPCs to dig carrots' that could have gone into things like a meaningful faction system and a conversation system that was more than 'pick an aggressive or cynical or sarcastic or sympathetic response but don't worry because it won't really matter'. Fallout 76 is too pretty, too cartoony, too simplistic. It's Fortnite with a Fallout-like skin on. There seems to be essentially no actual story line except some lame stuff about 'find the overseer' and popup quests. It's only 25 years after the bombs fell but already you see the full range of canon entities like the brotherhood and super-mutants where they do not exist in the timeline. I could theoretically see a multiplayer Fallout but it would have to be on totally different terms. This just feels like they are trying to skip having to do the hard work of story creation, voice acting, and complex quest trees and have us 'create our own adventure'. They tried to do online multiplayer, and also tried to keep some of the single player fallout feel, but those two things are incompatible and they wound up doing neither well. BAH I say, BAH. You kids GET OFF MY LAWN!
  6. while ( *( (unsigned char *)(0xD40B))) might work too. But I'm confused - if you are drawing graphics in a normal way, outside of the vertical blanks, then you are by definition not going to be drawing them while the vb is happening, so there's no point in waiting. Any cycles your program gets are always 'after the Vblank', right? Unless the goal is to draw a complete screen before the next vblank happens...? Anyway, I don't really understand what he's trying to do, so I'm probably off base. Sanny - I didn't really give him a solution, just showed some examples of how to use a little bit of inline assembler to handle interrupts. He's asking for something else i think.
  7. As far as I know, you don't have to wait for vblank to be over. You just draw your stuff, you'll be interrupted at some point but you won't know it and your routine will pick back up where it left off. The VBI won't mess with your graphics at all. It just increments some system values and does other housekeeping.
  8. Yaron - Why are you trying to wait until vblank is finished?
  9. Yep, sure can. Again, probably stay away from c lib stuff, but any regular c stuff would be fine, as long as time constraints are paid attention to. *edit* P I don't normally worry about, but I guess you could.
  10. A parameter-less C function (void func(void) ) is indistinguishable from an assembler call. If you set up a vbi() function and put it's address into the vbi pointers and do the other necessary settings for a VBI setup, your routine will be called each vblank. You do need to jump back correctly, and that requires an asm("RTI") and stuff, but its pretty easy to use the asm() functions in C. You can hook dli's too, but I am not sure how you would save the regs you need without asm. See the below functions. Using the asm() stuff in C is pretty easy if all you do is save regs, set a few things, and return. #define DLIST *((unsigned int *)560) #define LMS_MASK 0x40 #define DLI_MASK 0x80 #define JVB 0x41 #define JMP 0x01 #define SCAN_GR0 0x02 #define SCAN_GR4 0x04 unsigned char color_save; unsigned char bloo=(7 << 4 )+1; unsigned char noo=(7 << 4 )+15; char dl[256]; void dli0( void ) { asm(" PHA "); //save a //chain to next DLI asm(" LDA #<_dli1"); asm(" STA $0200"); asm(" LDA #>_dli1"); asm(" STA $0201"); //save color asm(" LDA $2c6 "); asm(" STA _color_save"); //load up color asm(" LDA #1 "); asm(" STA $D40A "); // wsync asm(" STA $D018 "); //restore a asm(" PLA "); asm(" RTI "); } void dli1( void ) { asm(" PHA "); //save a //load up color asm(" LDA #3 "); asm(" STA $D40A"); // wsync asm(" STA $D018 "); //chain to next DLI asm(" LDA #<_dli2"); asm(" STA $0200"); asm(" LDA #>_dli2"); asm(" STA $0201"); //restore a asm(" PLA "); asm(" RTI "); } void dli2( void ) { asm(" PHA "); //save a asm(" LDA #7 "); asm(" STA $D40A"); // wsync asm(" STA $D018 "); //chain to next DLI asm(" LDA #<_dli3"); asm(" STA $0200"); asm(" LDA #>_dli3"); asm(" STA $0201"); //restore a asm(" PLA "); asm(" RTI "); } void dli3( void ) { asm(" PHA "); //save a //load up color asm(" LDA _color_save"); asm(" STA $D40A "); // wsync asm(" STA $2c6 "); asm(" STA $D018 "); //chain to next DLI asm(" LDA #<_dli0"); asm(" STA $0200"); asm(" LDA #>_dli0"); asm(" STA $0201"); //restore a asm(" PLA "); asm(" RTI "); } void setup_dli_chain( void ) { *(unsigned int *)(0x0200)=&dli0; *(unsigned char *)(0xD40E)=*(unsigned char *)(0xD40E) | 0x80; } unsigned int next; void build_dl( void ) { int sl=0; dl[sl++]=0x70; dl[sl++]=0x70; //dl[sl++]=0x70; dl[sl++]=SCAN_GR0 | LMS_MASK; dl[sl++]=(int)&screen1 & 0xFF; dl[sl++]=((int)(&screen1) & 0xFF00) >>8; dl[sl++]=0; dl[sl++]=SCAN_GR0; dl[sl++]=SCAN_GR0; //dl[sl+0]=SCAN_GR0; //dl[sl+1]=JMP; //next=(unsigned int)&dl[sl+4]; //dl[sl+2]=( next & 0xFF ); //dl[sl+3]=( (next >> 8 ) & 0xFF ); //sl+=4; dl[sl++]=SCAN_GR0; dl[sl++]=SCAN_GR0; dl[sl++]=SCAN_GR0; dl[sl++]=SCAN_GR0; dl[sl++]=SCAN_GR0; dl[sl++]=SCAN_GR0; dl[sl++]=SCAN_GR0; dl[sl++]=SCAN_GR0 | DLI_MASK; dl[sl++]=SCAN_GR0 | DLI_MASK; dl[sl++]=SCAN_GR0 | DLI_MASK; dl[sl++]=SCAN_GR0 | DLI_MASK; dl[sl++]=SCAN_GR0; dl[sl++]=SCAN_GR0; dl[sl++]=SCAN_GR0; dl[sl++]=SCAN_GR0; dl[sl++]=SCAN_GR0; dl[sl++]=SCAN_GR0; dl[sl++]=SCAN_GR0; dl[sl++]=SCAN_GR0; dl[sl++]=SCAN_GR0; dl[sl++]=SCAN_GR0; dl[sl++]=SCAN_GR0; dl[sl++]=JVB; dl[sl++]=(int)&dl & 0xFF; ; dl[sl++]=((int)(&dl) & 0xFF00) >>8; ; } void activate_dls ( void ) { //set screen *(unsigned int *)(88)=&screen1; //kill antic by storing 0 into $22f *(unsigned char *)(0x22F)=0; //Then store the address of the new display list into $230 and $231 (low then high).

  11. Do you have anything in your source code named 'once'? See this: https://forums.nesdev.com/viewtopic.php?f=10&t=14315 It indicates that you have a 'once' segment setup, but you did not give it a definition in the cfg. Look for anything in yoru source called 'once' (especially a .segment). If you don't find anything, examine the files you are linking. If you are including any other files in your link than those that were directly produced by your source code, they may have that segment defined.
  12. It's for an ST Mac emulation, I think. You need the original roms.
  13. Yaron - I was in exactly the same place as you a couple of years ago. Then I decided to get over my config phobia and I just started working with it and learning. It makes sense once you get used to it, and it makes serious development MUCH easier in the long run. Well worth the effort. I wound up using it to define overlays and EXT ram loadable stuff and all kinds of things. Well worth the time investment.
  14. I've always seen people allocating extra size and at runtime adjusting the 'start' pointer via math that ensures a good boundary. Or, of course you can set aside a segment in the config, but OP said he does not want to do that.
  15. Notepad++ works well, and is free. You can get gVim (vi editor) if you are old school. You could try Atom, too, it's what the cool kids use nowadays. Also Eclipse. and then there is the WUDSN project here:https://www.wudsn.com/index.php/ide/installation *edit* Err, WUDSN is Atari, not user if it has support for TI stuff.
  16. Hah, no, that was a line of Burroughs 3500 OS command. See, WAY up above in post #12727 pacman said something about a burroughs mainframe. So, naturally I thought if I posted like 20 posts later it would make perfect sense, and all of the ex-Burroughs computer programmers here would have a hearty chortle.
  17. All Atari items are gone, based on PM order and lot size.
  18. The list is now: PM Respondents so far, in order of contact: #1 Nir Dary - claimed carts, so they are gone #2 Brentarian - the whole thing Citing potential spouse aggro, he now wants all 1200's - maybe some leftover 800's. #3 _The Doctor_ - whatever he can #4 eebuckeye - wants a single working 1200. Not doing that yet and these all do not work in some fashion. #5 Brenski - 1200's and 1050's #6 Clauseb - wants the sinclair pile. #7 Remo - wants a 1050. Not doing that yet. #8 Kheller2 - wants the entire atari pile. #9 Keneg - wants some of the drives. Not doing that yet.
  19. OK, - counts - 7 1200's all in varying stages of working. None work completely, some may be dead - most common issue is keyboard. 3 800's - unknown if they work or not, but they came from the 'something's wrong' pile 7 1050's 1 Rana (not indus, that was a mistake) 1 810 No 130's after all - was wrong about that 1 600 - found that at the bottom Weights - 1200's are around 6 pounds, 800's are 4 pounds, the drives are like 3 pounds each. So everything would be 7*6+3*4+9*3=81 pounds..lets say its about 90 pounds to be on the safe side, I'm using a bathroom scale. A quick check of USPS indicate it would be around 155 dollars to the east coast, so lets say about 175 to go anywhere US for the whole lot. The sinclair pile weighs around 50 pounds. And also, I'm looking for people who want to get all or most of these in one transaction, I don't want to worry about who gets what and if it's broken or not. All 1200's, all 1200's+800s, all disks, that kind of thing. The list is now: PM Respondents so far, in order of contact: #1 Nir Dary - claimed carts, so they are gone #2 Brentarian - the whole thing Citing potential spouse aggro, he now wants all 1200's - maybe some leftover 800's. #3 _The Doctor_ - whatever he can #4 eebuckeye - wants a single working 1200. Not doing that yet and these all do not work in some fashion. #5 Brenski - 1200's and 1050's #6 Clauseb - wants the sinclair pile. #7 Remo - wants a 1050. Not doing that yet.
  20. PM Respondents so far, in order of contact: #1 Nir Dary - claimed carts, so they are gone #2 Brentarian - the whole thing #3 _The Doctor_ - whatever he can #4 eebuckeye - wants a single working 1200. Not doing that yet and these all do not work in some fashion. #5 Brenski - 1200's and 1050's I want to make sure everyone understands the consoles all don't work in some way. The drives I don't know about. Right now I am going to get Brentarian a total weight, I'll post it here. The carts are gone. The rest I will weigh out over the next week (sorry, I'm busy) and will post here. I'll do it by system type. Things that are left will be offered to the next folks down the list unttil it's all gone or people don't want it. Thanks. You can still PM, I'll keep track of it and post it here, but it's not likely much will be left.
  21. Hi Folks. So, as I continue to divest my 8-bit stuff, I find I have a large amount of stuff that probably isn't worth the effort selling on Ebay, but I hate to throw away as trash. I took a shot at this a while back, but I stalled out. This time I'd like to just list by general content the stuff, and ask if anyone might be interested in paying postage and getting it otherwise free. Stuff like: 1. I have about 25 mixed 800xl/1200xl's, and about 10 or so 130xe's - I think some work but some may not and if they do work all have some problem like bad RAM, bad display, bad keyboard, etc. The case conditions are mostly fairly good, some are kind of dusty. The XL's are so heavy it's expensive to mail, I bet I am looking at about 100 pounds worth in total. I don't really feel like cleaning them and mailing them out one by one, so if someone wants a bulk lot of them for local pickup let me know. I'm in Omaha Nebraska. I am willing to bulk mail but like I said it'll be expensive. 2. I have a giant box full of Sinclair/Timex stuff, 4-5 TS1000's, a couple 2068's, a couple zx80's, a printer, a bunch of different memory packs from 16-64k, memotech keyboards, weird boards I have no idea about, etc. Also up for free local pickup or mail with postage paid. Or, if you'd be interested in taking the whole Atari and/or Sinclair piles, just let me know and I'll get a weight and a shipping estimate. Still free, just pay shipping. 3. I have about 6 1050's and an 810 or two and an Indus. No SIO cables, but the drives look good and work as far as I know. Also free bulk pickup or if you want to get it mailed bulk let me know. 4. 50 or so mixed Atari cartridges, no rares as far as I know, also free for pickup or mail if postage paid. If you are interested in one of the options, let me know and I will give you exact item counts and give you a postage amount. Thanks, Dan
