Dragon Buster

[jammajup]

Hi guys
I have a Dragon Buster on the repair bench at the mo,after replacing several 74 series and the 6809E ii still have a screen of garbage.The reset line on the 6809 is pulsing H/L this signal appears to be coming from pin17 of a 28pin ic @ 5A (J501X custom ic?) any idea where i can obtain a data sheet for this `J501X`?.
