According to at least the KA650 manual, it uses the
CD interconnect for address and the ribbon cable for the

like the PDP-11 PMI with the data along a sideband.
I'd be interested in cooking something up at some point.
I'd guess the KA630 would be similar.
The KA630 tops out at 16MB, while the KA650 can handle 64MB.

It occurs to me that a dual-width 16M PMI board is
something that would
border on trivial to make today and probably would have a small but
happy market. I know I'd definitely want to hear more if I heard of
such a thing. Is enough known about the PMI for that to be a
reasonable thing to contemplate?
Well the schematics for the KA630 are out there, and the documentation
seems pretty complete. I think it wouldn't be too tough, but that's a
guess, as I've not looked at the PMI area in any detail.
