A better way would be to look at what this prof in
Japan did -he's written a
complete working
pdp11/40 on a smallish altera fpga- - it even runs UNIX V6! and had an IDE
hd interface.

OK, this is seriously cool, and it's the first time that I've heard
about this project. I'll have to take a good look at this and update
my Emulation website to contain information about this (I've got an
FPGA section that covers all FPGA implementations of DEC CPU's that
I'm aware of).

here is the paper

Get the files here:
http://shimizu-lab.dt.u-tokai.ac.jp/ and note the VAX
780 project announcement.
They show here that they are nearly complete on their VAX 780 on a chip
project.
Both the 780&11/40 are written in SFL - a nice but unpopular C-like HDL.
This PDP is not microcoded.
The tools are freely downloadable as well as the PDP11/40 source - so you
can play
on winblows and linux. I got both versions of the 11/40 to run but alas..
they don't boot V6.
I'm wondering if they don't have a modified Unix V6 to handle the HD,
or are they emulating a known DEC Drive? Any idea what it would take
to boot something like RSTS/E, or RSX-11M+ on this?
Sad, as I wanted to use this as a front end to my PDP10
project written in
SFL;) As far
Your what project?
