Re: Vice: Commodore Superpet & OS/9 Multi disk units

Yes, OS/9 expects unit 8 and unit 9 …. i finally managed to perform a directory listing on disk10 (8250) using the waterloo microEditor (took several attempts) but as the os/9 files are contained in a ‘rel’ file, I don’t know how to decode it..

I have a few os/9 programs in a large ‘rel’ file that it seems can only be read on an 8250 (confirmed in Vice) … I only have an 8050 so was hoping could use VICE to transfer across to that format. A ram disk was another thought and then switch drive types etc.

Thank you for replying….
