I don’t expect to make a living from RetroShield but this Sunday I had an unusual surge of orders. I didn’t know what happened. As I was printing the labels, I realized it must have been hackaday.com because I had submitted my project there. It’s an honor to be featured on hackaday.com.
Well, I got several emails and feedback (thanks for all). I had to work on my other projects, but will switch to RetroShield for a few weeks to look into these ideas.
Feedback so far:
- What would it take to emulate KIM-1?
- Investigate Arduino Due (fast processor but requires 3.3V <-> 5.0V level shifters)
- Optimize code to get more speed (currently 95~100kHz)
- Can uP use Arduino’s GPIOs?
- Finish write-up’s already mentioned on website (geda/gschem, Z80)
- how can we add floppy support?
- combine processors into one PCB (this was my first prototype actually but I didn’t like the way it turned out; i.e. wrong processor could be inserted into the wrong socket and switching processors would mean removing the IC’s back and forth. )
