This is hex 380 bytes long so needs address lines A0 to A9 wired up.
A0 comes for free.

This is a big endian CPU, so the odd prom is the low order D0-D7.

The first bute of the program is 0x7A and this goes in the high/even prom.

Instructions for reprogramming the mixflash loader using mixbug. Aug-11-2003.


You will need three files:

        recuse-clearer.hex

  Step 1 - Solder up the eproms and get mixbug working with the flash at 0x20000


  Step 2 - Download the rescue-clearer into onchip ram and run it
               This requires two stop bits on the serial port to be enabled. Then 
               cat rescue-clearer.hex into the serial port.
	       
	       This loads at FFF400 and can be inspected with the mixbug D command
	       The mixbug command 'Gfff400' will run it and it should echo ABC and exit.

  Step 3 - Similarly, download recovery-oddette and run it.
                It should echo the a promt and then await the main download
                which can be done with the normal squirt program.
