Hey Dean, wow-wee must have both overlooked the piggy back board that was missing
Had i taken a decent look, I would have just referred you to Mike in the first place.
Hi Beaky, it was I who was going to send you some boards. I hadn't done so as I found a good, honest repairman to do a couple of immediate repairs. However as there are plenty more faulty sys80B boards, I will send you a couple and give you an email to confirm, along with the display if you still require it
