Aiming for the Atari

After wining the Atari XEGS on eBay, it finally came in.  Got the console, the keyboard and some game carts.  Cool beans.  I hooked it up to a 13" color TV and it came right up.  So it worked.  Now to tear it open and see what was inside.

A few turns of the screws later, I had the cover off and was looking at the motherboard.  I could see I had my work cut out for me.  The first thing I had to do was desolder the 6502C CPU, also known as the Sally chip.  So I fired up the soldering iron and solder sucker, then went to work.  About 30 minutes later, I carefully pried up the CPU, then I installed a 40 pin machine socket and seated the Sally back in.  I hooked everything up and turned the computer on.  It came up.


Now to desolder the 32K ROM chip.  Same song, different dance.  After carefully removing the solder from the pads, I gently pulled the ROM chip out, put in a 28 pin machine socket, soldered that, and put the chip in.  Fired up and it worked.

With those two chips socketed, I could now turn my attention to the truly awesome brain transplant: 6809, here we come.
