I wasn't entirely clear. The 8/L's and 8/i's have very accessible
interconnects as compared to the cluster of five OMNIBUS cards in
the 8/e CPU.

Yes. It's not the replaceability issue (not that I can burn bipolar PROMs)
It's the getting inside the CPU issue.

I didn't mean modern like IDE disks, though that's an idea. I meant
modern for the PDP-8 in general (RL8A/RL01, RK8E/RK05 vs DF32 and RF08).
Sorry I wasn't clearer; I was in a hurry this afternoon.
