I have one of the dual-power willems. I like it a lot, the best part was the price (only $40!). I haven't had any problems with it. I got mine from mcumall. I have been tempted to buy a new programmer because i want support for GALs and PLDs.

Does anyone know where I can find a composite video mod for my 400?
Any help would be appreciated.
thanks

I recently finished my MAME cabinet. I just ordered a trackball and some extra buttons, after realizing how much I need them. Can't play Quantum or Reactor without a trackball!

So I picked up an Intellivision 10 on clearance for $6. These have the NES in a chip in them, right? Is it possible to rewire it to run NES games, like maybe I could add a cart port or something? I counted the pins on it, but I think it lacks the connections for a 2nd player controller. Going by the NES in a chip pinouts on Kevin Horton's site, it has what I think is a 62256 SRAM connected to the Chr pins, and some strange mystery chip whose function I am not sure of yet. I would like to use it to make an NES handheld.

An A8 would be awesome for the FB3, if it actually happens, it might change my view of Infogrames. I have an FB2, and I am pleased with it. In my opinion, the FB2 redeems them for the FB1. But much more must be done before I trust them completely. I think the way to go is an A8 compatible with some built-in games, built-in BASIC, and an external hard drive that could be sold separately. Maybe an SD type of memory cartridge that looks like a 5 1/4 floppy disk, that would be really cool. The drive for it would be bundled, and look like a mini 810.

I think that the reason my apple //e enhanced doesn't work right is because it was upgraded to enhanced by the previous owner. I'd like to try replacing the roms in it to see if I can get it to work.

Epyx 500xj all the way, best damn stick I've ever had. I use with all my old stuff and new stuff. c64, 2600, 400, FB2, Homebuilt 6502 sbc, etc. I use it on my pc with PPJOY, for various emulators.

I don't think it is the actual ball that wears out, but rather the little plastic guides that the bottom of the stick sits in. The ball is just there to create a pivot point for the stick. When I opened an old controller, the guides were much thinner in the middle than they were at the ends. I'll post some pics later if I remember. All N64 controllers,(or at least all of the ones that I have seen) including 3rd party designs use this. The 3rd party ones are connected to pots, instead of the optical assemblies that Nintendo uses in their version, and in their gamecube controllers.
My N64 controller of choice is Performance's Super Pad. It takes a little getting used to, but I like it better than the official ones.

I have a theory as to why switching the roms made no difference. I traced out the connections on the board, and found that both roms share all of the pins. The A12 line goes to the chip selevct line on each of the roms, I think that the chip select on the low rom is active low, while the chip select on the high rom is active high.
I think now that the problem is with the atari 400, not the cartridge. I made an eprom cartridge with the basic rom stored on it, booted it up, and it did the same thing. It gave me the ready prompt, but the keyboard still didn't work. I am at a loss at this point. I'm not sure what to do. I'll make another eprom cart with a game program on it, and see if that works.
How would I go about making a Basic Boot disk? I upgraded to 48K, so I have enough memory now, right?
-
How can I convert an .atr disk image into a .cas file? I built the SIO2PC cable, and have tried both SIO2PC and APE, but can't get my 400 to boot from the emulated disk drive. Am I doing something wrong? All you have to do is load the disk image into ape and turn the atari on, right? I did manage to get it to boot from a .cas file using the .cas loader in ape, but that's all I could get it to do.

Kangaroo. Figures.

Once Basic is loaded, none of the keys do anything, including the reset button. I don't have a disk drive or any other software for it so I have no way of testing it. I checked the solder joints on the cart and they seem to be good. I noticed that the roms inside were socketed, so I removed them and re-inserted them to try to clean the contacts on the sockets. But that didn't make a difference. Also, just to see if it would work, I switched the roms in the cart. But strangely enough, I still got the READY prompt and the keyboard still didn't work. That really confuses me, I would think that the two roms in the cart were high and low roms, but then how come switching them didn't give me a garbled display or something?
-
I tried cleaning the contacts on the cart, but it didn't help. When I boot up the cart, I get the READY prompt, but none of the keys on the keyboard do anything.
-
Yes, it works without the basic cart. I can type stuff in memo pad.
-
I just got an atari 400 off ebay, it seems to work, but when I boot up the BASIC cartridge that came with it, the keyboard doesn't seem to work. Help!
-
I think that the problem is the AY3600 chip. I'm not sure though, and I don't know where I can find a replacement.
-
That didn't seem to work, but I think that the keyboard rom dump you have is missing a few bytes.
BTW, my keyboard rom is part# 342-132-B, not 342-151 which is what it says in your dump.
-
There is one ribbon cable that comes off of the keyboard to the motherboard. I tried removing the keyboard rom and booting it and it didn't seem to make any difference at all.
-
When I turn it on, the disk drive spins, and if I hit ctrl+openapple+reset, it reboots.
If I hit ctrl+reset, it gives me the prompt, but typing doesn't work. I tried taking all the cards out, but I still can't type anything.
-
I just got an enhanced Apple //e with a 64K ram/80 column card, a Super serial card, and a Disk II card w/ a pair of drives for free. But I don't have any Dos disks, and I don't think the keyboard works right. I've never had an apple // before. When I turn it on, it checks for a disk to boot to, and of course can't find Dos on it. If I press "control+reset", it gives me a prompt with ] and a blinking square, but it doesn't respond to any keys except for "control+reset", "control+(open apple)+reset", "control+(open apple)+(closed apple)+reset", and "control+(closed apple)+reset. None of the other keys seem to do anything, and they don't display on the screen. Am I doing something wrong? or is there some way to hook up a Disk II to a PC, like the Star Commander for Commodore, or do I have to find a way to load Dos from a tape?

I don't know if Dark Chambers would fly or not, but Guantlet would make an interesting movie. I think that this year is the year for videogame -> movie conversions, because the Doom movie recently came out, and I heard that a Metroid movie, and a Diablo movie were in the works.
-
I have a Willem I got from MCUMall for really cheap, and it works great! I'm running windows XP and all I had to do was install a driver that allows the software to access the printer port. If you use any priter port joystick convertors for game controllers, you probably already have the driver installed.

I hate Dragon's Lair.... I feel that there are enough crappy games for the 2600 already, no need to add more....
Oh well....to each his own, I guess.....
Besides, if you modify the atari to run it, it's not really an atari anymore is it?
I thought that the whole point of programming the atari was the limited hardware...
If you just add more memory when you need it, you're following the mindset of most of the programmers today, memory is so cheap nowadays that they just write sloppy code, and increase the memory requirements...

I would kill for a V64...
