Hi there Poly fans,
Check out my web site which has some more details on the progress of
my disassembly project.
The more time I spend on this the more I think portamento is very,
very doable.
And also, I am finding that the disassembler I'm using, along with a
few hours here and there, is quite enough for me to think I'm making
some real progress which is all I need to keep my optimism up.
Sticking with this is nothing more than a labor of love.
Some early successes here is that the MIDI part of the machine code is
so compact that it is going to be quite easy to remap the UART into a
different address location. That will give the needed 8K of space for
an additional ROM. Also, the space inside the 8K boundary above the 2K
6116 RAM is completely unused so replacing it with an 8K 6264 is going
to be relatively easy.
