An 800 xe board will fit precisely(when looking from the outside of the mega case). if you hold the 800 xe board in front of the mega st case, you will see that there are on the left and right about 0.5 centimeter is left... post some pics when you're project has some progress ! Thelen

Great idea ! but I think it won't fit because the board of an 800 xl is too wide for the case... Thelen

Anybody seen this webpage ? http://membres.lycos.fr/pmandin/en/ports.html very cool ports of doom, heretic, hexen and quake ! But now the big question : are those playable on my mega atari STE ? if not, what do i need then ? I've downloaded a zip packet, and there's a ttp file in it....that's an executable for my ste....but after loading a while, it jumps back to tos.... I have no idea how I can get this game working with the WAD files etc.. and when starting the ttp file I get the message : parameters ? Thanks, Thelen

atari Tennis Thelen

Sad to hear , but I understand your point. Thelen

Great !! nice to screens from games where I've never been before... Thelen

What a great little game ! and very nice graphics ! Thelen

there is an atari 8 bit version in the mini game compo 2003 called 'superfly 1K'! really nice : http://starbase.globalpc.net/minigame/ Thelen

This is absolutely great !!! Keep up the good work! Thelen

- your new site does look good..... thelen

ah, now is see, you want to make an eprom programmer for the atari 8 bit :wink: I was thinking it was for a pc :wink: The programming voltage is indeed a problem....and the pins on the joystic port too. Now i'm thinking about that, why not make some kind of cartridge that can program eproms ? Thelen

a dc->dc converter is a regulator, when having a DC voltage of 18V, and connect it to a 7812 regulator, the output will be 12V......connect it to a 7805 regulator, you will have 5 volts as output.... but i don't really see the problem, when programming an 2732 eprom, 12V model, you can just connect the program voltage constant to VPP, Only when /CE is lowerd for the right programming time, the data will be put in the eprom. thelen

I don't think it's difficult to get a 12V programming pulse ? just use a 7812 regultor, and you can use a thryristor to switch it on or off ? over the years I've built lot's of things, sort of eprom programmers too, but a little more specialized, Ram cartridge programmers fot the atari 2600 and atari 8 bit Thelen

What kind of eeprom is it ? not a serial one ? :wink: It will work, but how many ns is the acces time of an eeprom and a epprom ? When the atari won't get it's data within a certain time, it will hang.... Thelen

I think that the main problem is, that a complete board won't fit inside an XL or XE machine. and not all people can solder and wire (lot's of wires - I'm getting sick of soldering wires ) the whole thing up (without any faults). I think an external board is a great idea, you don't have to modify your atari (or really small things), and you can swap the unit ! Thelen

for playing Movies or music on the atari ? what do you mean by that ? That machine you're building sounds awesome, But will it stay compatible with the real 8 bit stuff ? Thelen

WOW !!! That's a very intresting project !!! and you get 4 extra players + missiles ?! Thelen

Great news to hear this game will appear on the 8 bit machines !! I think a disk image will be the best idea, almost every 8 bit user is using disk images instead of real disks, and all game carts are available in disk form. Off course, a cartridge is much more spectaculair I think....when I ever finish a game, I will release it as cart (image) and as diskimage I think. as Callipygous and Video game addict are saying, there are less atari 8 bit cart collectors out there Thelen

Great graphics ! looking forward to see this game for the 8 bit ! Thelen

you should set the Player/Missile priorities. this will make it solid: lda #$1+16 sta gprior ;set player/missile priorities this would help, but there can be set lot's of playfiel/ P/M priorities... http://www.atariarchives.org/agagd/chapter5.php on half of the page is standing a diagram Thelen

I think it's a good idea ! Thelen

I'm interested in it too. Thelen

The only thing that's missing are the sprites i think. Ok, we have 4 one color player/missiles. In my opinion it would have been a good idea to upgrade the atari 8 bit line in 1984 with some extra hardware, with some sort of sprite chip. Maybe a nice homebrew hardware project ? Thelen

I have more of those carts in that case with that label. I think it's not so rarel, but since i'm from europe, maybe it's an european cart or a pal cart ? Thelen

you don't have to use multiple charsets either, you can also copy new data to the character location in the characterset! so you can get many animation for various chars, and nu need for 10 charsets ! instead of using 2 scrolling antic 4 lines, you can also use a player. the same player can horizontally reused for stars etc. I think there will be enough time to give your sprites a new position. keep us informed about your progress !
