Has any one had these problems listed at this computer site with retro bright www.classic-computers.org.nz/forums/viewtopic.php?f=11&t=894

It may not be a schematic but a helpful discription of how it work is at this web address http://www.computinghistory.org.uk/det/16684/Atari-Touch-Tablet-CX77-Light-Pen/

True, but by the time you add exchange and posting it makes buying another machine locally cheaper, for you guys in the States it cheap enough to replace the keyboard. Last quote I had for a 130XE key board was $30USD post plus the keyboard at $25 making a total of $55 USD , compared to a complete working 130XE I picked up for $30 NZD only a few weeks ago. And even on EvilBay I have seen 130XE's go for under $30USD True, but we are talking about the OP, and he is in the US ;') sloopy. I never had any keyboard problems with my XEs, is that because i don't beat the s**t out of them playing games -lol- Don't use the 130XE for games I have a bog standard 800XL for that and it takes all the punishment and has done since 1984, any other work I use the Newel expanded 800XL also owned since 1980 The 130XE"s owned since 1985/1986 have never functioned long enough to consider use for any thing much and only get used occasionally, mainly due to the Keyboard failures since 2001 no use at all. I vaguely recall reading that the XE keyboard can be fixed by peeling off a plastic sheet and repainting the traces with graphite. Does anyone know if this is true? Not tryed that one. I vaguely recall reading that the XE keyboard can be fixed by peeling off a plastic sheet and repainting the traces with graphite. Does anyone know if this is true? I don't know about graphite specifically, but there are plenty of circuit trace metallic paint pens and similar products that are brushed on with a fine artist brush. They are conductive paints. If graphite paint can hold a current of electricity, then I guess it could work too. And the XE aren't the only keyboards that can have this problem. 1200XL's have a couple types of keyboards and at least one of them has the Mylar plastic sheet keyboard circuits as well, and possibly other XL models since quite a few different keyboard manufacturers were used by Atari over the years. Honestly, I've tried two different types of conductive paint pens and neither has been very good at actually drawing the traces. I always end up squeezing out a few drops of the paint and applying it with a small brush anyway. Tried them but found the repair was only short lived, before cracking again either in the same place or a new one. At the moment I am looking at a mod that will give my XE's a proper circuit board for the keyboard so I will not need to keep replacing the Mylar, or trying to repair it.

I think you would be better of keeping the 800xl, of all the A8 I have had the only one to give me problems has been the XE's mainly the keyboard traces cracking, and replacements are not cheap if you can still find any, I find that the 800xl Newel upgrade to 256k is by far a better machine than the XE , it seem better built for a start.

Just did a search for an 800xl part C061428 came back with Ic M74ls138p substitution 46-13782-3 $5.31 add to cart seems worthwhile checking some other Atari part numbers to see what they have in stock

130 XE Myler trace fault, may need keyboard striped and trace cleaned, or just re seated into Motherboard, if this fails you need a new myler trace for the key board ( I bought a 130XE this week with same fault, cleaned myler up and reseated it in to mother board all now working fine) 65XE Sounds like a ram chip has failed ( use google translate to view answer)

Looks like a standard 800xl key board, if you goto Atarimania and download the 800Xl manual that came with the 800XL you will see its the same keyboard ( UK version I think) Just checked the 600XL manual shows same key board, but the monitor jack is where the TV channels switch is normally shown ( US Version)

Not sure if its of any help, but I seem to remember that the 1010 even new was prone to errors due to the low grade resistors used and a fix was to change to better quality ones that were + or - 5%, I seem to remember the fix was listed in either Atari User UK or Page 6 mag in about 1986 or 1987 So after all these years the resistors could be iffy at best.

How much for the Donkey Kong with Postage to New Zealand please?

Seems to me , you have to be a multi millionaire to legally avoid paying taxes, perhaps if you increase sales you may be able to end up paying less taxes than a secretary. At least thats the way it seems to be reported about your presidential candidates and the US tax system down here.
