old 85 jb starion 2l ecu 40 pin eprom

[throwed]

hi all , does anyone know what 40 pin (20 each side) eprom they used in the 1985 jb starion australia release .. the standard says MH6356-2218 and under that E-122 i know they do exist as i have a another chipped ecu and that runs the car like a rocket but they have rubbed the eprom part number of it ... so if someone could let me know what type it is i could use my eprom reader writer and rip this one i have in to a bin file and make multiple copies

cheers all
christian
