Hopefully someone can help me out on this one. A chip on the I/O board burned out in our 1996 VF2. The chip name is PAL4.4 and has some Haas firmware. Haas will only replace the entire board $$$$, and will not sell a replacement chip or give us the firmware to burn on a replacement chip, which you can buy for a couple of dollars.
Does anyone know what firmware is on this chip or have a copy of the firmware on this chip?
