Hi folks,
This is a little sideways from on topic, but no too far. Is there a good open source
implementation of a pdp11 for fpga in verilog/vhdl that works well for Unix v6+? Google
turns up a number, but I’m hoping some of y’all have actual experience with one that you
could recommend over others. I’m financially challenged so it’s a requirement that it run
on cheap fpga’s not some Tesla prototype :)
Regards,
Will

I know of two:
https://opencores.org/projects/w11
and
http://pdp2011.sytse.net/wordpress/pdp-11/
Both projects are so old, they should run on FPGA boards you probably
could get for free ...
Have fun!

I need to find those free boards :). Those are the best sites, I’ve seen, too. I’m not
entirely sure why I’m wanting to do the fpga thing when simh seems to work just fine for
everything I’ve ever wanted to use it for, but having a switch controlled machine that can
be put on a shelf and taken off and plugged in and run is appealing. Not quite as
appealing as having a PiDP-11, but for those of us on a budget, it seems right somehow!
