A83: Re: Need help with rom page
That page in the last message was found by accident, and so funny I had to
post it :)
Anyway, I'm not for certain where this is documented, but setting the ROM
page for area $4000 requires writing to ports 0 and 2. Bit 4 of port 0
controls bit 3 of the page number, and bits 0-2 of port 2 control bits 0-2
of the page number. Credit for this info goes to Rusty Wagner (VTI source
code). Note that port 0 also controls the link port, so I'm guessing that
the proper way to change the page bit is to read the port first and only
change bit 4.
