Just sending a thanks for the replies from various folks on this list. I was able to recover a partial set of operating system files for my IMS/LF-Technologies S-100 machine from members who dug deep into their archives. It's booting now to a basic single-user TurboDOS 1.4 which proves that my hardware is sound. In order to get what I really want out of this machine, I still need to source a full set of TurboDOS 1.4 drivers (.REL files) from IMS L/F Tech distribution diskettes. I'll be around if they ever turn up.
Thank You!

I've got all the pieces except for the Operating System. I'm hoping that someone here may have a disk stashed away. From the literature I have read, I would need TurboDOS version 1.40a or 1.41c from IMS or L/F Technologies. I've seen TurboDOS 1.3 versions out in the wild from IMS, but the 1.4 version was greatly enhanced and offered better compatibility with my specific hardware. I'd be much obliged if anyone can help.
