The pal chip that I need is a 20 pin with the number CO61618. I can't make out from the photo if it has that number on the 800XL. It's right below the cart slot.

 

I took another look and snapped another picture of the 800XL motherboard on my lap (which was a mistake; my black pants turned dirty-brown).

 

 

Here's a picture of the chip.  Who knows if it works...?

Here's a photo of the EPROM burner I made that plugs into the joystick ports and uses a modified version of the EPROG assembly program I had to rewrite to work with it from ANTIC DEC 1985.

 

For reference, the four-page article is called "Build Your Own EPROM Burner: Chip Programming for $30," by Larry Woodgeard and Charles Cherry is on pages 69-74 of that issue and can be read here:

I love homebrew hardware!

THAT'S THE CHIP!

Time will tell if it is a good one.

Here are some photos of my homemade modem I built

 

Seeing this modem makes me really want to access the PLATO service on a real Atari through IRATA.ONLINE.
