SBJC lives once more, with many thanks to Player, with the help of sorting a replacement mpu4 board, and testing of the game cart

Now the problems really begin....

Everything works, apart from the fact I have no lamps what so ever, No 8-seg's, but main alpha works fine, so something makes me think I have made a booboo plugging in the wrong cable to the MPU.

Anyone spot any issues so far, or able to give me an idea what could be the issue (Possible fuse fault maybe?).

Just a side note, found out who made the PSU for this, and it surprised me that it was a company that used to operate from just down the road from me in Beeston, Aerial Components.

Dead link stan....

Links now fixed (Sorry, have started on my Southern Comfort, and now feel nicely oiled )

Update, have now re-fitted the plugs on the mpu, according to the following: MPU4 service manual - TheFnet

8-seg's now work, and given the 34v fuse the torch test to see if it had blown (It works fine).

Lamps still dead.

Any ideas?

Think I've found the problem after having a chat with Magik....

34v fuse holder on the PSU, has gone all brittle and cracked, thus not making proper contact with the fuse. Also connector side looks like it has overheated at one point, melting the protective plastic spade cap.

Also noticed most of the spade connectors are barley biting into the fuse holders, so questionable contact between the fuse and the respective holder.

Now, question remains.... what would be the correct fuse holder to get? (Think I may as well change all of them, as the others are starting to get like the 34v)
