Does anyone have a list of Barcrest MPU4 Error codes they would share with me please?
Trying out some old program cards i acquired. On 2 of them all i am getting on the 7Seg display is 5.1 (Cant remember if this is Eprom error or checksum)
On another one i am getting "Bad Jackpot Key" on the display, two others are just sitting there not doing anything at all.
The two others seem to boot ok, but (bear in mind i am trying these with a psu,reel unit, 7seg and lcd display connected up only) just showing 0.00 0.00 on the lcd and no attract text flowing along the disply?
Thank you.
