Also I did not mention earlier my PDP-8 diagnostic page:
http://www.ak6dn.com/PDP-8/MAINDEC/
has more or less what you asked for. It has all the base PDP-8e series CPU core
diagnostics as listings
in PDF, binary tape images in BIN and RIM, and disassembled sources in PAL and
assembled LST.
BTW my PDP-8 implementation in Verilog (not VHDL) passes all these diagnostics,
as well as running
chess, focal, and other such images.

Hi,
1) DEC documentation which more fully describes all the instruction set (in
more detail than the PDP-8 handbook)
Not DEC documentation but a good resource:
http://homepage.cs.uiowa.edu/~jones/pdp8/man/
I've written an emulator purely from these pages and it passes the
MAINDEC-8E-D0AB-PB instruction tests.
Here is IAC described:

2) Some more instruction tests in assembler
source code format. I have
found lots of binary files but I would prefer assembler source code format.
I am using a pal compatible cross assembler.
I don't have any of those. But
I've used Krten's d8tape to dissasemble
BIN files with good result:

That and the source code listings on bitsavers.
