Appealing to NZ and Aussie IGT Imperial people CAPX chips

[Igtpoker]

Hi Fellow New Zealand and Aussie slot owners I’m trying to get hold of 4 Capx chips for 4 different IGT Imperial games.

Games I have and chips required as follows:
Blue Moon : CAP275 chip
Sheer Magic : CAP278 chip
Castaway: CAP280 chip
Cashline aka Double Bucks: CAP291 chip

I have all the other game chips for each set MXO, MBO, MRO, MGO etc but am missing the smaller CAPX GFX chips

Currently using  a players edge US chip but the colours are completely wrong for the game.

Just to give you an idea of the type of machine I have a picture below of What the game should look like with the correct CAP chip  this picture was found on trade me a while ago Blue moon with CAP275

Any help will be much appreciated.

Am I correct that you had at least one of the CAP chips and broke a leg off of it?

If so, you may be able to perform some surgery to make it work well enough to read it in your EPROM burner and duplicate the chip.

With a sharp precision knife like a scalpel, try scraping away a little bit of the brown/black chip material right where the broken leg was connected to the chip. You should be able to expose a little bit of the metal that led to the broken leg.

Now, solder a short bit of flexible wire with an exposed/stripped end to that metal. Once you have that jumper wire attached, carefully insert the chip into your EPROM programmer, and carefully insert the jumper wire into the pin slot where the broken leg would have been. Now try to read the EPROM into your computer. If you're successful, you'll now be able to burn that code to a new blank EPROM. Good luck.

Alternately, you could try just soldering a more rigid metal wire to the exposed metal to make a temporary replacement leg, as seen here:

You are absolutely correct! Unfortunately I tried soldering the leg back and tried putting it back into the board the whole pin broke off the chip so now I’m left with a broken chip and No CAP left I wished I’d have tried to back it up with my programmer as I have blank chips ready to use. Very frustrating!!

Well, a hard lesson learned, and hopefully you've taken the time to backup your other chips to multiple places for any future catastrophe.

Is there any chance of ANY of the metal still being visible on the edge of the chip, in the "sandwich" between the brown or black material, as seen circled in the attached image? That's where I was saying you could use a scalpel to remove some of the material to expose a little bit of the metal and then solder there. You don't have much to lose at this point...

Not that I can see it’s completely sheered off not even a fraction of metal left . Almost thought I had a glimmer of hope then.

Again since you have nothing to lose, consider trying to cut into the plastic (or whatever the material is) of the chip to see if you can expose any metal for that leg. Obviously you can't cut the whole chip open, but if you can chip away a fraction of an inch/fraction of a centimeter off and expose some metal, you might be able to rescue the data.

This video might give you some ideas on how to attempt it:

A couple of commenters on the video said they used a dremel tool to expose some of the missing metal.

Hi again Knagl just another update still no good was able to cut a piece off and exposed a small fraction of metal and try and solder some metal on but the chip reader still can’t read it. some of the other pins on the chip are starting to go bad as well just have to hope I can get another Cap chip from someone, It was worth a try.
