Review remarks: User Guide 2nd edition, version 15 September about mega65-user-guide

Thanks very much for the detailed review!

Re: preferred mouse port: Starting with v0.96, the mouse (and paddles) will work in both ports.

Re: internal links, they're working for me in macOS Preview. It would be odd for them not to work because they are generated by LaTeX. If you can reproduce this, which PDF viewer and operating system are you using?

Re: COLOR: "COLOR ON/OFF" has been removed from the ROM and the manual. "COLOR number" is still an alias for FOREGROUND.

Re: adding ASCII to the PETSCII table: The FONT entry has the ASCII character table, including the codes. Several tables currently found around the BASIC reference ought to move to their own appendices (e.g. system palette is currently buried with BACKGROUND), and I can imagine moving the ASCII character table as well. I also want a screen code table. Right now I'm balancing further production work against hitting a print deadline, so it might not be in the 2nd edition, but it's on my mind.

Re: quick reference card: It appears in portrait orientation for the purposes of online use of the PDF. We'll make sure this gets printed landscape, just like last time.

All other feedback incorporated. Thanks again!
