Not quite, you still need bus interface and buffering. I havent looked at
PDP-8 memory interface to see how and what. I have one or two
PDP11 proto/ww cards that with careful cuts for power and ground will
work fine for omnibus.

The trick is doing battery backup so it also behaves something like
core. ;)
