Quick KIM Clone Update

LEDs are working…

There is one obvious problem that I’ll think about this week, but all of the major stuff needed to run KIM-1 programs are in place and working.  No cuts or jumpers yet, but might be required to fix the one known problem.  Only a few of the buttons for the keypad have been installed but any key can be “pressed” with a jumper.

Once the current problem is fixed, the other 6532 and SD card connector installed.  If all of that works, then I might add a header to get to the 6502 signals.  Personally, I don’t see a need to add expansion capabilities, but several people have asked for it.  I also need to consider whether to have a bit of a gap between the 4th and 5th LEDs to make it clear the left four digits are the address and the right two are the data.

This looks close to a real system now.
