In the mid 80s there was a rather good FN in Hereford railway station cafe and considering it was in a railway station which have a notorious reputation for being set to low percentages, played a really good game. Once I got that random first square on the board, lights flashed and went straight to jackpot and held 5 times meaning £18 in tokens. Of course, there were the times when you had to manually nudge and end up with 10p. Ij don't think I played NBN in the wild. I remember that clockpot streak on STC. But didn't rival the mpu3 streaks but I did enjoy the game. I think I did play the early S&G rom machines but didn't really understand the siginficance of it sadly. My favorite sys80 was bouncer. We had one in our local put and was a great machine. On one occasion, a player got the feature hold after feature hold on the nudges and lit all the fruits and kept holding. It emptied of tokens after it had payed out £24 pound of £3 jackpots. Never saw a cickback. I didn't like Nudge Steppa much, found that rather tight and felt cheated when you got the second nudge feature only to get a 1 and no advance. Clickerty Click was certainly an innovation in those days but you were in big trouble should you encounter any sticky buttons. Are they your YouTube videos? The series of ones Stele L played such as cash blitz, tumble etc?

Hi Andrew and Midibob Many thanks for the info ... that a great help ... regarding the 5v Yes i can see now you mention it .. that there is a 7805 reg and caps just under the switches (marked on photo below ) that's great so i will add the 5v regulator to my circuit On the Aux Board.pdf ... the transistors are Drawn as NPN transistors ... can anyone confirm if these are NPN please .. if that is the case then i will use 2 ULN2803 Darlington arrays to keep the board size down whilst looking through the downloads today i came across a document uploaded by Riche100 showing the circuit of the Alpha and some test rig info unfortunately it was all jumbled up in wrong page order and blueprint pages .. had an OCD moment and decided to re-organise it and tidy it up here is the updated document .. i have joined the diagrams and put them in A3 format hope this helps someone ... all the best Dicky barcrest mpu4 test rig instructions and drawings for alpha display etc testrig update.pdf

Sounds like it's a 3D printer for Birthday/Xmas.

what is the wiring / circuit for the port interface module for MPU4? I only have MPU3 circuit!

Nice!! like the reels in the top too! I want small reels like that for my MPS reel set!

...and quick too! My rig took about a year to design, build and test.

Very impressive, a great piece of design and build..
