AS6C6416 4Mx16. Someone even uses it raw on 5V bus with no level translation, just tiny Lattice LC4064V cpld for address decoding. https://www.amigalove.com/viewtopic.php?f=6&t=1689 https://www.amigalove.com/viewtopic.php?f=6&t=1689 https://hackaday.com/2021/01/08/the-amiga-1000-still-receiving-new-peripherals-35-years-later/#comment-6309849 https://hackaday.com/2021/01/08/the-amiga-1000-still-receivi...
- Androda 3y agoYeah, I noticed that chip and didn't give it a second look. It's more than 3x the cost of the PSRAM solution, and that would have driven up the price of the RAM card higher than planned. So sure, it exists. And that's about all I have to say about it.
