Was chatting with Ira Baxter, who wrote SDOS... and early OS for the 6800 and 6809 machines. He said that his sources were all on a hard drive that crashed and he hasn't gotten around to trying to restore the hard drive.

The manuals for SDOS is on bitsavers... but no disks..
He did say he donated a full Jupiter system way back to the SF Vintage Computer club.

Anyways, trying to locate the disks.

Thanks
