Hm, interesting point of view... The 11/20 is the simplest 11 as far as
I know. No microcode that can go bad.
The core memory systems are quite reliable. And if there's a problem,
they're not that difficult to fix.
For me it's important that the computer has core memory: It's a big part
of the fun!
The sc memory systems are too close to modern hardware. Without
blinkenlight panels or at least LEDs instead of incandescent bulbs.
Not to forget: More vintage -> More cool ( -> higher value)
A pdp11/34, /44 or any QBUS machine can ever be as cool as a 11/20,
11/40, 11/45/, /70 and so on.
I somewhere have an 11/45 with full core memory (something over 200k).
But the CPU has issues... :-(

I have the impression that 11's with core in are harder to fix, so the pool
of buyers are smaller... 11-20-

Haha, those low-brain comments!
