Lost Forth Rom

[Don Latham]

Help! my Isopod Forth interpreter has Alzheimers! Many words have disappeared, including WORDS and SCRUB. I haven't used any vanish words to my knowledge. How do I reinstall or find out if the EEPROM is NG? In addition, does my isopod really have only 8k of eeprom?

If the IsoMax kernel is not corrupted you can simply jumper or short out SCK/PE4 to GND on J5 pin 2 & 4 respectively then reset or recycle the power to get the IsoMax prompt back and enter SCRUB to erase the application program and you can reload the new program again.

If the kernel is crashed you need a JTAG-10P-Cable to reflash the fresh IsoMax kernel.
