<div class="moz-cite-prefix">I've seen this same problem when
running the 780 simulator on other platforms. If you wait about a
minutes after the boot has finished the console usually starts
responding again and is fine thereafter. Does the console recover
on the Raspberry Pi? I've not looked into what causes this so far.<br>

<title>Not Responding to Console on Raspberry Pi</title>
<!-- Converted from text/rtf format -->
<p dir="LTR"><span lang="en-gb"><font face="Calibri">I built SIMH
on the Raspberry Pi (Debian) and have been running it fairly
successfully. Recently though it has stopped responding to
the console, for no reason I can determine. After it has
booted VMS (this is the VAX 780 emulation) I press enter to
get the login prompt and nothing happens. If I press CTRL-E
it halts the emulation, but fails to respond to any further
key presses at the sim> prompt. If I change the console
to be telnet then I can use telnet to log in to the machine
etc, perfectly normally. This is really puzzling, has anyone
ever seen something like this?</font></span><span
