Has anyone seen this game before?

just wondering if anyone has seen this game before?

Chieftain

aristocrat branded.

esprit set up, have some manuals which help as a guideline. but cannot find exact manual for the year it is. not stamped on metal tag thing.

5 reel

if you don't have reel glass and reel mech you might be in for a big hunt , lots of those went to scrap yards

[clarkman42]

i have all that..


have taken alot of stuff out because i am writing my own wiring diagram for this machine to make it easier to fault find and future reference

[Op-Bell]

It looks like an Esprit. You'll find links to the manuals I just posted in another thread.

[clarkman42]

cheers, i already got hold of those manuals, just not much info on the circuit diagrams. .eg components.

[Op-Bell]

Oh, can't help you much with circuit diagrams for the boards.

Are any of the ROM files for these machines available?

I have one with 4 x 2716 ROM's. One of which is corrupted.

The ROMS are labeled:
"7Y187
MAGIC TOUCH"

Thanks,

I have a memory dump from a 3 EPROM version - unfortunately that probably isn't much good for you.

When you say "corrupted", what do you mean and how do you know? If it reads all FF it's probably toast, although there is a chance it was always blank and just put there as a filler. If not, it may be possible to read it at a lower VCC - try putting a diode in series with pin 24 to drop the voltage by 0.6V. Then try it with 2 diodes.

<edit> just to expand on that ....
EPROMs work by trapping some electrons in an insulating layer deep inside the chip - this is called the stored charge. The detect threshold, ie how much charge you need, is proportional to the supply voltage. So if (for example) it's 50%, then at 5V the stored charge in the gate must be more than 2.5V. When EPROMs are programmed, the VCC is often raised to 6V - this is not related to programming, but to verifying. If a cell verifies at 6V, then it has a safety margin at 5V. The trapped charge leaks away over time (time measured in decades) until eventually it falls below the threshold for VCC = 5V. So often, when an EPROM is old and losing its charge, if you lower the VCC below 5V, the charge is higher than the threshold again and it can be read.
