Language Lab Lines: 18 I have made several modifications to my 600XL and 800XL, and I was contemplating posting instructions on how to do the mods to USENET. The mods that I have done are: 1. COLD-RESET button on the XL (and presumably the XE, though I haven't tried it.) 2. Video monitor jack on the 600XL (includes composite video, composite luminance, and audio, but no composite chrominance. However, on my monitor, I have seperate chrominance and luminance inputs, and I run the composite video output into the composite chrominance input with out any problems.) 3. Simple 64K upgrade for 600XL. (Requires 2 RAM chips, and 3 wires.) If anyone is interested in these mods, send me mail, and if there is sufficient interest, I will post instructions to the net.
