. I have a switch on the extra address line (these are 8Kx8 instead of the stock 2732 4Kx8), and I can put two chip images and select one to run on. I did this both to avoid the uv step and because I was tired of standing on my head to change chips - now this board sits on the transmission tunnel and I can reach it from the drivers seat with no problems. Eventually I'll box it up and put it in the glove box. For now I have about a 2' cable on it, but I am going to try a longer one just to see if it still works. John Spina lists a chip switcher on his website but when I tried to buy one he said that he had reliability problems (noise issues) and didn't want to sell them. It's not a full emulator; I still have to physically move the chip back and forth, but it's better and faster than the old way. I got 3 boards made (that was their minimum) but I used my only spare socket to populate the first board. Are the carrier-style sockets still available or have they gone the way of the carrier?
