Is there an online resource that has a definitive list
of DEC modules and
their descriptions?

The Field Guide is my primary source of info. I've printed it out at about
6pt,and then stappled and cut off the excess paper, folded up it's about a
3" square, perfect for putting in ones pocket.
I'd like to configure a Heathkit H11 as a *small*
PDP-11 with just CPU
(M7270 LSI-11/02), terminal, and paper tape. I have no cards for it now,
but I've got the M7270 on order.
Which cards do I need for RAM, serial, and parallel I/O? I know nothing
about DEC buses. Do I need a bus terminator or anything else? Also, I
recall that something about the H11 wasn't DEC compatible, but I don't
remember what it was....
For what you're wanting it doesn't matter that the H11 wasn't DEC
compatible, you won't be running a H11 you'll be running a LSI-11 in a H11
chassis. I'm not familiar with the H11, but on any Q-Bus backplane I've
used the terminator seems to be built in (at least I've never had to worry
about it).
You'll need a RAM card, a SLU (serial), and whatever a paper tape
reader/punch interfaces with (SLU also I assume). A copy of the
"Microcomputer Processor Handbook 1979-80" or equivalent would be a major
help for you also. It includes a section on memories. Not sure what else
you might need for a setup like you want.
