The sio2pc board really wasn't that hard. I have been interested in electronics since I was 5 years old or something so I know how to solder and am pretty good at it. Yeah I know what you mean about the enjoyment and all. I got into Atari when I was three years old. We got two 2600's from the trash back in 1999 or so. Sadly we had to throw it away because the joysticks, games, consoles, well pretty much everything, was too worn out to keep cleaning in order to get it to work every time. When I learned about the Atari 8 bit series, I fell in love. I liked the idea of a computer being pretty much the size of a keyboard (with some extra bulk to it), and on top of that, it played old Atari games! If you look in the picture closely enough, the keyboard is a little messed up. I had to open the Atari multiple times after buying it on ebay. Once to clean the contacts on the cpu and memory board to fix a rolling screen, again to adjust the color, and a third time to grease the button that opens the cartridge door because it was getting stuck. Eventually the keyboard ribbon cable broke and the return key stopped working so I opened it again and thought maybe the button was broke and tried peeling up the keyboard (bad idea looking back on it). Its all good now though. I ordered a replacement keyboard from myatari.com and it works again.

here is my "collection" although it's not much of a collection compared to some of the other people on here if you ask me. the little board on the right is an sio2pc interface that i built. apparently I also got someone's shoes in the picture. the cartridge on the lower left is Q-bert. I didn't realize it was upside down when i took the picture.

thank you. This was the site i was looking for. I would never have found it without your help stevem00.

I need an atari 400 replacement keyboard. I found a site selling one about a month ago but now I can't remember the name. It wasn't Best Electronics. It had multiple sections and the list of products was text only. Does anyone know the site I am thinking of? otherwise does anyone know of another site that will sell atari 400 keyboards?

if it doesn't work please tell me. it is probably just a typo.

if anyone is still interested the forier program is listed below: 10 GRAPHICS 24 20 SETCOLOR 1,0,14 30 SETCOLOR 2,0,0 40 DEG 50 COLOR 1 60 FOR A=0 TO 319 70 Z=0 80 FOR F=1 TO 17 STEP 2 90 W=(1/F)*SIN(F*(360/319)*A) 100 Y=INT(192-(95.5*(W+1))) 110 Z=Z+W 120 PLOT A,Y 130 NEXT F 140 O=INT(191-(95.5*(Z+1))) 150 PLOT A,O 160 NEXT A 170 GOTO 170 My dad made this when he was in college and it was originally written by him for an IBM PC XT with EGA graphics I think. this one is based off of a port I did for my calculator actually. the original used the WINDOW command which would let you use the screen like graph paper but my calculator did not have this and neither does ataribasic. since I made the calculator port first, all I had to do was change some of the values that were screen specific (mainly resolution related) and it worked. my dad also had the program draw the square waves that the added wave would become but i have not got around to that. you can add a STEP .5 to line 60 to make it twice as accurate and twice as slow.

these are pictures of the even and odd vertical lines as well as the program that showed me the problem in the first place. it is a forier series analysis demonstration my dad wrote on an IBM PC XT 25 years ago that I ported to atari basic. so adding s-video would solve this you said?

I have an atari 400 w/ a GTIA (not sure if this matters) and when I plot a single white pixel on the screen in BASIC, (hue 0, luminance 14) the pixels red color is sometime offset to the left making the pixel green or the blue to the right making it purple. when I put two pixels next to each other, one pixel becomes white while the other still looks wrong. Does anyone think the composite video modification would solve this? The attached picture is of a "white" pixel in the middle of the screen in GRAPHICS mode 8. it is hard to see but the blue is separated out to the right

thank you for the replies and the information. at the point where someone said the heads will disintegrate, I knew it was a bad idea to buy the printer. however i was still curious as to whether or not it was compatible with atariwriter

you told me that already. I did not need to hear it a third time, it is not helping.

to ask it for the third time, is the 1027 compatible with atariwriter? I dont want to hear that the head will disintegrate. I just want to know whether or not it works with the cartridge version of atariwriter.

I am actually thinking of upgrading to an 800 at one point. I was thinking of using the 410 anyway since i have a bunch of old recordable tapes that i am never going to use. even if the print head is melted to nothing, is it compatible with atariwriter? the seller also says that the item was never used but the power supply and cables were taken as replacements (it was from an office enviroment). would this make a differenceI can ask the seller if he/she can feel the print head to see if it is squishy to test the condition, right? I have had similar problems with old 8 track tapes where one of the wheels would turn to a sticky black goop and destroy tape players. some websites told me to feel the rubber part that disintegrates to see if it is soft. i would assume that the same test would work with both as it is the same concept of rubber turning to mush. does this sound like it would work?

Does any one know if the 1027 printer is compatible with the 1025 or otherwise works with the cartridge version of AtariWriter? I know atariwriter works with the 1025 but I do not know about the 1027 and i am curious because there is a (relatively) cheap 1027 on ebay right now. I just bought an atari 400 on ebay a couple of weeks ago and i am looking to build a complete atari system (printer, 410 or 810, no modem)
