Jeff, there is a fully commented OS65D3.2 listing on the net. Have you got that?

Dave, I found more info and have updated Upload3. I have created a bunch of .LOD files of OS65D from my image files and successfully re created a boot disk from these using winOSI. Will upload these soon and detail the process I used. I hope to serial these to my Superboard and using the same proces...

Uploaded C1P_OS65D338_1.65U an 8" image for winOSI or dump to your OSI. This is the same as the OS65D338_1.65U image for the C2/C4 but with the appropriate changes for the C1P (standard video) ie inverted keyboard, screen format and ACIA locations.
