[Simh] Problem with UC15 simulator

[Ray Jewhurst]

I am running the current version of Simh on a Dual Core, Quad Pipeline Core
i5 (3rd gen) laptop with Linux Mint.  Every time I go to run the sim this
is what I get:

ray at ray-Inspiron-5537 ~/Emulation/UC-15 $ pdp15

PDP-15 simulator V4.0-0 Current        git commit id: 15fd71b9
sim> set dr enabled
sim> set cpu api
sim>

Ok everything's fine with the PDP-15 and now I go to start the UC15 I get:

ray at ray-Inspiron-5537 ~/Emulation/UC-15 $ uc15
Fatal simulator initialization error
File open error
Hit Return to exit:

Any ideas?

Thanks

Ray

ps I am running them in separate Term windows per instructions.
