Also I did not mention earlier my PDP-8 diagnostic page: 
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.
