| aaaa | anyone familiar with the | 07:52 |
|---|---|---|
| aaaa | xc2064 project? | 07:52 |
| aaaa | I'm looking into various retro chips and wondering if the xc2064 is documented enough that it would be possible to replicate / simulate it? | 07:52 |
| aaaa | specifically - i'm wondering if there's enough tooling / documentation that i could trivially build a simulator and have some way to place simple designs (even hand-routed is fine) onto it | 08:15 |
| mangelis | out of curiosity: what computers/consoles/etc use xc2064 ? so far i only found some cd-rom drive for amiga | 08:18 |
| aaaa | afaik an early apple machine used it for FPU? | 08:24 |
| aaaa | i'm mostly interested in messing around with the 2064 for the sake of itself, but it would be nice to have some baseline to go off of | 08:24 |

| mithro | aaaa: We have always planned to bring up the xc2064 project as a simple "my first FPGA" demo but haven't ever quite had the time to do so | 20:55 |
| aaaa | ah | 21:33 |
| aaaa | so for now, the bitstream stuff + reverse-engineering stuff + datasheets is all there is? | 21:33 |
| mithro | The bitstream documentation still needs some work around the IO tiles IIRC | 21:39 |
| mithro | The cells and routing is all there | 21:39 |
| mithro | aaaa: There was some recent discussion around this on twitter | 21:39 |

| aaaa | hmm okay | 22:02 |
| aaaa | but there's no actual model/emulator of the whole chip available? | 22:02 |
