The data sheet specifically suggests these can be used for dual cache and for cycle-steal DMA. I haven't heard if anyone actually ever did this though. |

| Hmm, I think the pacemakers came much later, although I see what you mean about safety-critical designs. I'm not saying WDC were wrong to add the signals - for one thing, the idea that the 6502 makes unexpected memory accesses might ... |
