[comp.sys.atari.8bit] Hardware modifications to the XL

ken@hpclkms.HP.COM (Ken Sumrall) (09/27/89)

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.
