Hello, all:
I've posted the schematics and the beginnings of a kernel tonight. The c
ode is not to a point where I can simulate it yet, but I have the reset, NMI
, and IRQ routines done, as well as necessary modifications to Chris Ward's
ACIA and Dallas RTC code.
Please look at the schematics. There are 9 PDF files containing the 8 sc
hematics and a component mask. I appologize in advance for using PDFs for sc
hematics, but I've found that it's easier to print from EDWin to the PDF Wri
ter driver and then to the printer than directly to the printer itself.
See if there is anything glaring that I've missed. At this point, the My
6502 feature set is "frozen", but I'm open to circuit optimization ideas. I'
ve gotten the board down to 6.5" x 7.5". When you look at it, you'll see tha
t it's stuffed.
Enjoy it and let me know what you think.
