OK, I want to know how to do four things from BASIC on the Plus 4...
1. First, how do you move the top of memory? (On the 64 you poke location 56) 2. How do you BLOAD something off disk into memory at a certain spot. (Know how to do this on 64, but not on PLUS 4) 3. Which location do you poke to change where the video chip is looking for its font information. (54272 I think on 64... But what about PLUS 4?) 4. Which location do you poke for multi color character mode?
So what I want to do is to move the top of basic up to make room for a custom font, then bload the font in, switch to that font, then turn on multi color character mode.

I haven't done any Plus/4 programming yet, but MagerValp has, so I asked him what docs he used. He gave me some, and I threw them up on my website: www.psw.ca/docs/plus4/Almost certainly the answers to your questions will be in there. Did the REU information help?

Yes, the REU info did help, thanks.
