Ok, folks... Here's part 2: http://jonsharp.net/retrocomputing/bare-metal-macintosh-programming-part-2/ I'm still playing catch-up, documenting the things I'd done a while back now.  As I mentioned above, I managed to get some of the newlib stuff working.  But this write-up covers the font...

Bunsen, Man, you're right there with me.  I've been wanting to do a simple FreeRTOS example for this once I have the newlib stuff working properly.  I had seen MBOW's uclinux work for his homebrew machine and had in fact taken some of my inspiration from that project.  It at least demonstrated...

Hey all, Thanks for the feedback!   Bunsen:  a vt100 terminal is precisely one of the ideas I had.  It's non-trivial, but not terribly sophisticated, either.  I've got a few other ideas, too. ;)  And I like the idea of loading more code over the serial port. MidnightCommando:  Yes, I've...

techknight: you are probably right about the hacks/development section... Maybe I'll start a new thread there detailing more of the font routines, etc., and the linker issues I'm experiencing now...

Thanks everyone, I appreciate the feedback. Elfen: Yes, I'm not sure exactly what bootstrapping of the framebuffer the ROM startup code is doing.  It was an open question for me.  And it's partly why I said "with any *real* help from the ROM/System..."  My end goal would actually be to create a...
