Progress update -
I have got the machine running but to quickly proove the board I confess to cutting corners with lazy unsightly link wires. I can now choose to go back and do the thankless task of repairing the broken tracks and sealing the board - see you next year (possibly) with the results (if I can last that long without moving the machine on lol) 😂
The bit I really admire is the painstaking time and effort required to repair (properly) broken traces on PCB's - that takes skill, practice and serious patience ! I shall see how I go on with any of those three attributes!!!
Thanks to matty here on the Mecca for the new remade stealth game card and also loaning his MPU stealth board to prove the physical machine itself (prior to me trying my own board yesterday afternoon).the machine was, I am glad to say, all fine (just some usual bulbs out).
Regarding game play - its not a particularly polished machine (imo, sorry to any fans out there) and is quite different to my usual "go to" JPM's and Barcrest. I don't think I have ever played a Global clubber/stealth tech before but its not an instant attraction but I am being a tad unfair on just a few minutes play. I do like the beer holder coin tray and hopper tho (first hopper for me like I said in the OP).
Pic of the board in and running where you can see a nice bit of dodgy linking going on (the red and black is the fly wired battery off Matt's brand new gamecard), but it's working in every aspect. I had an initial glitch on first power up with the original MPU where reels 2 and 4 juddering (not spinning) but that was just me missing one tiny crucial link for a data line input to the bottom row of IC's (including the reels).
