- I worked out a rudimentary design a few months back, but haven't had the time
- to test/implement it, so it's still on paper at this point.
-
- DMA and Autoconfig kind of fall into your lap if you're only planning on
- hooking up one slot. It's for multiple cards that you need things like
- Buster and bidirectional bus buffers.
-
- I have a text file of my design that I posted a few months ago to see if
- anyone here could confirm my design, but I only got one reply. I was going
- to send a copy to Dave for comment, but I haven't seen much of him here
- lately, so I assume he's busy. If you want to see it, mail me. Maybe you
- can finish development. I don't really care who takes the credit for it
- just as long as it's done and the instructions are freely available.
-
- As far as I can see, it's pretty much just some wiring, a few flip-flops,
- and some combinational logic for the DSACK/DTACK conversions & such.
- I may work on it over the summer if I get the time.

- ...Sean.
