If it weren't for Commodore, the machine would have become the Atari ST and it would not have had a multi-tasking OS and it would be relegated to game system status..
Rumor has it that the
1850XLD was intended to have a "Unix-like GUI kernel." This could have been either Unix itself or possibly be CAOS-based. However, this was all pre-Tramiel, so they probably would have done something different. It's a moot point, though, because Jay had no intention of working with Jack and the boys, which is why the back-room, last-minute deal with Commodore occurred in the first place.
