MAGIK

Ghost train by empire mabye? very early 90s?

Reflow solder on the plugs for red and green also, they easily crack. And look in the plugs both sides make sure youve not got a broken pin the leads are getting on for 40 years old!

Check the resistor pack thats connected across the reel opto inputs on the board. You will get reel A fault with no reels connected ! with nothing plugged in all reels will appear to be jammed. If all the reels are spinning normally and your getting reel A fault, look in the back of the machine and see if you can see the reel opto lamps ( early cabs actually had incandescant bulbs for the light source in the opto sensors) lighting up. Sometimes they can die. If a reel is shuddering or not moving its more likely to be a drive transistor or one of the ICs buffering the reels (74LS0

It does exactly what it says on the tin. Its an old fashioned 2708 /2716 eprom emulator. You use the emulator box to plug into a board where the real PROM should sit and you program the box with your code, so that you can see what it would do in whatever board /piece of equipment your testing. Quite an old, and rare find!

If you dont get that blue battery off that board, and get all the corrosion cleaned up , all the carbon tracing removed, and the traces repaired and reinforced itll just go boom again.

ah ! looks like an appolo9 rebuild.

Bellfruit scorpion 4 , especially the later smiley 2 stuff is handy for the operators because theres a ton of spares around. They are everywhere! But from a collectors point of view the golden age is the late 80s early 90s, lots of absolutely iconic system 85 and scorpion machines still knocking around to this day.

someone needs to get a hold of the tech docs out the office while they clear out! Sad news to hear BFM closing but not surprising, the internet is destroying all other walks of life so this is no different.

Now that will be a bit of rareness - they must have made a 2p kit for the seafronts! I wonder how it plays when compared to the 10p ROM.

thats a lovely machine, bloddy tall cabinet tho I had one a few years back tricky to get into the living room!

funny you should mention that.... maygaytest.BIN

Thats a nice crystal MPU4 that one. wouldnt mind seeing a gameplay video!

key to maygay is test the RAM pins with a logic probe while there is no card in. They should all be floating (not HI or LO) . If any are showing a signal theres a shorted IC on the databus. Second key is a magic number - 20C0. In nearly al M1 games the very first instruction in ROM ( at 2800h) loads a register with 1. The next instruction after that writes the value in the register to location 20C0. That happens to be pin 4 of U11 on 1A and 1B which sets IOenable to HI , ie turns it off. That in turn sets RAM enable at the PAL chip ON. If you cant do that, you cant peform a RAM tes

Your possibly a little off on your MPU release dates crest , stop the clock was released in 1984 was it not?

nice to see this thread revived!
