- | Delayering is typically more risky to the chip and myself (toxic chemicals like hydrofluoric acid). | + | In short, I focus on chips that are of interest |

- | In general I want to focus on R&D / labwork | + | Delayering is typically more risky to the chip and myself (toxic chemicals like hydrofluoric acid). Similar issues with staining and lapping. |
- | Most of this is targeted towards small chips up to the mid 90' | + | I prefer |
- | Other: most of the work is in decapping, | + | In general I want to focus on R&D / labwork and not hand digitization. I do have some limited semi-automatic digitization capabilities for planarized chips though that I'd like to develop (ex: works on PS1 chipset). |
- | Please provide the following information for each chip: | + | Most of this is targeted towards small chips up to the mid 90' |
- | * Required: markings on the chip | + | |
- | * Do not just send me the chip code name and expect me to know which one it corresponds to | + | Other: most of the work is in decapping, |
- | * Ex: specify " | + | |
- | * Optional: alternate names | + | |
- | * Ex: SWIM, Pentium 1 etc | + | |
- | * These are helpful | + | |
- | * Required: what you want | + | |
- | * Full images of every layer so you can digitize it? | + | |
- | * Do you need the whole die or just a part of it? | + | |
- | * Top metal image for aesthetic purposes? | + | |
- | * Are you hoping for high resolution that can see every wire or just an overview shot? | + | |
- | * ROM dump? | + | |
- | * Suggested method? | + | |
- | * Image mask ROM only? | + | |
- | * Erase fuses / laser magic? | + | |
- | * Optional: datasheet | + | |

- | * Required: replaceability/ | + | |
- | * Sometimes I can do something more aggressive (faster, sometimes much faster) that might have higher chance of damage | + | |
- | * If they are readily available you should send me several just in case | + | |

- | * TODO: come up with a scale, but here are some rough figures | + | |
- | * Very common: < $5 or can easily | + | |
- | * Ex: XC2C32A | + | |
- | * Common: can get more if you shell out mild cash | + | |
- | * Ex: playstation | + | |
- | * Rare: You can probably get more but it might take a while or cost >$100 | + | |
- | * Ex: playstation | + | |
- | * Very rare: $1000 or un-replaceable | + | |
- | * Ex: CSG 4510 R3 (the C65 CPU) | + | |
- | * Any other relevant information | + | |
- | * Can you provide any funding for the work? | + | |
- | * Commercial or personal interest? | + | |
- | * I' | + | |
- | * Funded projects are given priority | + | |
- | * I am willing to do a lot of stuff for free, but it does involve harsh chemicals, costs me money, and time so anything is appreciated | + | |
- | * Any legal issues associated | + | |
- | * Does release need to get restricted? | + | |
- | * DRM? Crypto? | + | |
- | * Ex: a sound chip is no issue | + | |
- | * Do you have a particular timeline in mind? | + | |
- | * Between | + | |
- | * Coordinate with me for best results | + | |
- | * I usually have the most time late Dec / early Jan | + | |
- | * By default I retain copyright and publish work CC BY on sipr0n | + | |
- | * If you need exclusive copyright, want to be included | + | |
- | Still reading and interested? | + | Chips are non-returnable. If you need something back, please make an explicit agreement before sending. |
