Today, I got my first ever Atari 8-bit computer, and Atari 800. This one is a pretty late production run (late '83) and has a Mitsumi mylar keyboard. About 80% of the keys on the keyboard work, and I really like the feel of it, I just wish it worked better. I have heard of silver paint being used to repair the traces on the mylar, but I'm unsure of how safe it would be for me to do this, as I have just started messing around with these things. Another problem is that I can't seem to find the correct silver paint. When I look on ebay, there are either large vials of silver paint for a very high price, or syringes from China with tiny amounts that I don't exactly trust. If somebody has a really good guide on how to do this repair, knows somebody who could do this repair for me, or knows where I can find an appropriate amount of good silver paint that doesn't cost too much, I would really appreciate it. Thank you.
