I picked up all four machines this morning. The two LCs and one of the 660s work. The other 660 seems to have no video. The two 660s have cracked cases as well as one of the LCs. I took the full 040 chip out of the dead 660 and put it in the best LC. It also got a 2gb hard drive out of my LC III and a 32mb ram simm. Both the LCs can with ethernet cards. With a new pram battery the upgraded LC booted right up. Maybe I'll take board out of the LC with the broken case and put it in my LC III. That machine whistles at times so it seems at least part of its board is going anyway.
