I saw their website. Have you used it? Is it good? Thanks, 5-11under Other information I should have mentioned in my first post: This is for a Windows XP environment. KiCad would pass this requirement.

Yes, I'll be using surface mount parts for as much as possible. Mostly SOIC, as a compromise between solderability and size. Based on having several connectors, switches, and such, I'll definitely be above Eagle Light's limit of 4" x 3.2" 5-11under

Hi there, I need to create a 2 layer PCB that is about 4" x 6" or so. In the past, I've used FreePCB, which is okay for smaller boards, but I'm afraid it won't work well with relatively complex boards. I also see that the free version of Eagle is size-limited. I'm wondering if anyone with some experience with other PCB layout software can recommend a solution for somewhat larger and more complex boards? Ideally, I'd like it to be free, or pretty close. Any help would be appreciated. Thanks, 5-11under

I've found one, but if anyone has another, please let me know. Thanks, 5-11under

The problem is that shipping a 99/4A will likely cost more than the chip is worth. 5-11under

Hi there, I'm interested in purchasing a TI TMS9918A chip. I'd like to try it in a ColecoVision, to compare with the original TMS9928A chip. The TMS9918A is the one that outputs composite video (yellow RCA connector). I'm not sure exactly what these go for, but if you have any, feel free to send an offer. For mailing purposes, I'm located in Ontario, Canada. Thanks, 5-11under

Nice.

Hi opcode, I like the simple approach, and for $50, with DKA, I would definitely buy one. This is coming from someone who doesn't own a single homebrew, except my own. The CF and MegaRAM are very appealing to me. Thanks, 5-11under

Primary: Atari 2600 Secondary: ColecoVision Intellivision Atari 5200 Tertiary: All the rest Rationale: I'm guessing that the Atari 2600 outsold everything else combined. I'm guessing that each of the secondary consoles outsold all of the tertiary consoles combined (or at least pretty close). I could be wrong, 5-11under edit: pre-crash, of course.

Hi everyone, There's been some suggestions to have a switch installed on a ColecoVision to be able to switch between ColecoVision operation and Atari operation, while keeping an Atari expansion module plugged into the system. There's 5 lines on the expansion slot that need to switch "open" to run the ColecoVision. Pins 11, 27, 31, 35, 39. Closing them will run the Atari, of course. Note that I haven't actually tried this with any sort of switch yet, so I don't know the limitations on wire length, bandwidth requirements, etc. I just masked off the appropriate pins to get the ColecoVision to activate. Bonus: if you want to add a pause button (aka "Add-a-HaltTM") to the ColecoVision (not to the Atari), put a switch between pin 50 (Wait) of the expansion slot and ground. Note that this doesn't turn the audio off. You might want to account for that, too. Maybe this will be useful to some of you. Thanks, 5-11under

I love carts... and so do my kids. I find scratched DVDs and CDs around the house , but the N64 carts that are lying around work just fine. . I'd like to see a console with some sort of flash memory cart (built into a decently sized, relatively indestructible case). You'd probably need some extra RAM in the console for speed, and there's still the fact that the retail price of 4GB flash memory is around $12, versus less than $1 for disc media, but maybe that's not too bad. Thanks, 5-11under

It doesn't have to be that difficult. Three boards (and three cartridge ports?) and some logic for controllers, output, power. Thanks, 5-11under

Hi jeremysart, I'm guessing the Intellivoice "I" sits too far forward in the Intellivison II, which is why the internals would require modification? For the molding, I'd consider doing it yourself... although it's going to be a lot of work... make your own mold, and cast the parts yourself. Probably not a project for the faint of heart. That grill on the top might need to changed... . Good luck, 5-11under edit: I don't own an Intellivision anymore, but it sounds like a great idea.

Hi everyone, Like the title says, I see that DealExtreme (not me!) has Atari Flashbacks (the original 7800 style) available for $34.95. That sounds kind of pricey to me, but shipping is free, so maybe it's not too bad of a deal. http://www.dealextreme.com/details.dx/sku.27790 Thanks, 5-11under

Hi opcode, PM sent. Thanks, 5-11under

Do you want the pof file? The current implementation isn't very useful, as the ROM cartridge is placed inside the pof file, so you need to recompile the whole thing every time you want to change game. Furthermore, the way they implemented the thing limits the cartridge size to 16KB. Finally, the code I have here is a mess, so I will be doing my version from scratch... or almost.. Anyway, if you want the pof file (with DK) let me know... BTW, good to know you also have a DE1. Perhaps you could help me in the future... Hi opcode, The pof file would be a start, to make sure everything is working. However, the source files as an addition would be best, or at least the files that are different from the FPGA Arcade version. I'm pretty green at vhdl, but this sounds like a good project to get my feet wet. Although it may be pretty complex, I guess if the building blocks are organized, it could be manageable. edit: so yes, I'm willing to help out as I'm able. Thanks, 5-11under

Hi Opcode, I've got a DE1 also, because it was really cheap at the time, and I've wanted to try the FPGA Arcade CV for a while now. Care to share, or am I going to have to try the conversion myself? Thanks, 5-11under

8KB I believe. But the OM offers 24KB, since it is cheaper to buy 32KB than 2 ICs of 8KB nowaday. Hi Opcode, Is the OM RAM part of the regular memory map? If so, are you only using the 16K from 0x2000 to 0x5FFF, or are you somehow going beyond that, into the space mapped out by the 1K internal RAM? I'm just wondering if there's bus contention issues (and how easy it is to access the OM RAM)? For those who would have to look it up, like I did, 0x0000-0x1FFF is BIOS ROM, 0x6000 to 0X7FFF is the 1K RAM mirrored a total of 8 times, and 0x8000 to 0xFFFF is cartridge ROM. Thanks, 5-11under

Just make sure running into tufts of grass doesn't "kill" you. More variety would be good, and the ability to use the fire button to jump, if no other actions are required. Thanks, 5-11under

Hi Opcode, I'm curious how much RAM is required for your upcoming projects? Thanks, 5-11under

I agree with cybercylon - start up simple, then consider the stand-alone. Thanks, 5-11under

I agree that Defender was tough. I never got the hang of all the buttons. Two friends of mine used to play together, one person doing the flying, the other doing most of the rest. Starcastle wasn't too bad, in my opinion. It definitely got tougher, but after a few rounds, I mostly flew vertically, on one side of the screen, and every cycle up, if the shields looked good, I'd rotate my ship temporarily, fire a few rounds, then rotate straight up again, and accelerate. Thanks, 5-11under

Nice interview. Kind of a video game Freudian slip: "there is no more rom for your own imagination". thanks, 5-11under

I haven't seen the videos, but the graphics look great! Thanks, 5-11under

I'm curious how much Sears and Coleco would add to number? Thanks, 5-11under
