I have a sound digitizer that I built for the std bus standard, and
lately I've been toying with the idea of jumping it to the expansion
slot. There are a couple of signals required like IOREQ*, RD*, WR*,
on the z-80 std bus that I'm not sure what the equivalents are (if any).
Are there lines that come close to these?
Since this is only for me, I'm not concerened about being compatible
with the ACME box/board/drive/software standard. I'm leaning towards
fixing its address somewhere in the unused zone; any one have suggestions
on whats a good address for this? (this is an idea that I picked
up from the JFORTH booth at the SF commodore show, where they had
hard coded an LED display in a similar manner, if memory serves, I recall
they used 0x70000) Any problems with this address? Whats the lowest
address I can use? (I kinda get the feeling 512k is the noninclusive
lower bound)
Your thoughts and ideas, heck, even flames are welcomed!
