After a long look I have bad news . There never was an editor for the SPLIT 8 for a PC . Only Mac and Atari . The Split 8 was made from late 84 to mid 85 and was a dismal failure for SCI . It just didn't make it long enough to get a PC editor . Back in 1984 and 85 there wasn't much available for PCs . It was all Mac and Atari with a little C-64 . Sorry , but I looked everywhere . Get a Mac , you need to anyway so why wait .
