Wow! You are fast! Fantastic.
I also had the idea of ram at the bottom and rom at the top,
however I think $2000 is a bit low for rom and suggest rom
from top of space working downward as needed except for
having 8k or so of rom area at $cooo just like the cts of a
coco, thus allowing coco cart software debugging on a real
coco.
Since you are so quick maybe I'll let you design "mini-coco"
with me providing suggestions instead of the other way
around.?
I can easily draw up a TTL memory mapping circuit but to do
so in hardware would take quite a bit of board space which I
was hoping to avoid(physical space). If I desing the memory
map as if it were TTL could you then convert that into a
PAL/PLD Jedec equation?? you see I have been in electronics
for some time (30 yrs) but am new to these devices?
