Hi Joseph, # cp hptmconf myconfnf # echo 4dc >> myconf looks like a typo. If you actually typed this, all that would be in myconf would be 4dc. You need the contents of hptmconf plus 4dc. Otherwise you'd be missing some important devices.

FWI: You'll probably have better luck with the KL/DL interface. And it's already in the system, since the console is on the first one. # cp hptmconf myconfnf # echo 3kl >> myconf If you are really adventurous with simh, then configure the DH11 and it's associated DM11 interface, which from a performance standpoint work a lot better and have all the RS-232 signals supported [which is something one of the PiDP folks was recently trying to get going]. # echo 2dh >> myconf # echo dhdm >> myconf ᐧ On Wed, Oct 20, 2021 at 6:51 PM joseph turco &lt;italian.pepe.32(a)gmail.com&gt; wrote:
