 In short, I focus on chips that are of interest to me.  I do lots of chips for others, but I give priority to people that are able to provide funds. In short, I focus on chips that are of interest to me.  I do lots of chips for others, but I give priority to people that are able to provide funds.
  
-In terms of consumables, equipment wear etc, each simple chip costs me about $20 to decap/image (not counting huge equipment NRE).  As of 2014, a professional shop charges around $100 for a simple, low resolution top metal dceap/image.  People give me upwards of $150 per simple chip if they are feeling generous and want to support other projects.  Simple => not implant ROM and preferably does not require delayering.  Not sure what a shop would charge for delayering, but lets say upwards of $100 donation for delayering.  Chips from the 80's should be simple.+In terms of consumables, equipment wear etc, each simple chip costs me about $25 to decap/image (not counting huge equipment NRE).  As of 2014, a professional shop charges around $100 for a simple, low resolution top metal dceap/image.  People give me upwards of $200 per simple chip if they are feeling generous and want to support other projects.  Simple => not implant ROM and preferably does not require delayering.  Not sure what a shop would charge for delayering, but lets say generally 3x the cost of top metal imaging.  Chips from the 80's should be simple.
  
 Delayering is typically more risky to the chip and myself (toxic chemicals like hydrofluoric acid).  Similar issues with staining and lapping.  Lapping is currently extremely labor intensive and not very well refined (although I can get a small area easily). Delayering is typically more risky to the chip and myself (toxic chemicals like hydrofluoric acid).  Similar issues with staining and lapping.  Lapping is currently extremely labor intensive and not very well refined (although I can get a small area easily).
