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.
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.

The 8/e is all TTL as well (or at least mine is)... and the only 'custom'
parts are a couple of programmed ROMs on the EAE cards. But the
maintenance manual gives enough info to re-create those ROMs if you have to.
Yes. It's not the replaceability issue (not that I can burn bipolar PROMs)
It's the getting inside the CPU issue.
The appeal of
the OMNIBUS machines is that it's easier to
hang modern devices off of them.
I've never tried that. My 8/e has a PC04 (converted PC05, actually), TU56
and RX01 on it. The RX01 is a little too late for the period of the rest
of the machine, but it's useful...
