I hope this is enough information for someone on here to identify the fault. Perhaps it's a simple repair I could do myself. Can anyone recommend an Atari repair service, preferably not far from London, instead of halfway round the World? I never owned an Atari until 2 months ago. I was encouraged to buy a retro computer by features in the TV series BBC Click, about how computers today are being used just as communications devices, not for computing, as well as the fact that an Atari 8 bit was nearly my first computer, but I ended up with a shitty Commodore 64 instead, complete with its 1977 PET style BASIC with no commands for colour, graphics, or sound!
AFAIK, I last used my Atari 65XE yesterday, when I was running the ALPA Assembler which I typed in from the book "Atari 130XE Machine Language for the Absolute Beginner". I typed in, ran and debugged this program, then typed in and tried to assemble the first example from the book, which prints the letter A in the top left hand corner of the screen. It wouldn't assemble the program, though. I doubt if any data from any of my programs would have damaged any chips or been held in RAM while the power was off, or after a reset.
