EDIT: Mistake in the topic and can't edit, it's 128 KB / 1 Mbit.
In my absurd quest for a 20 MHz overclocked XT clone, my 70 ns RAM is holding me back and I'm stuck at 15 MHz! Going to 16 MHz makes goofy things happen, and beyond that it won't POST. I have a 16 MHZ rated V20 already so it's not the CPU. I had the same issues when I was using a 10 MHz V20, the only difference is it got hot when it was doing it.
Does anyone know if a 50 ns or faster DRAM chip is available that's compatible with this? https://www.datasheets360.com/pdf/6019545828535065751
I've been unable to find anything so far. Hopefully I won't need to make some kind of custom adapter to use a more modern component.
