I don't think it would be a terrible idea to understand just a
little bit more to know what start up files to edit, but I
certainly do understand not wanting to be bothered with
something. If I remember any more, I'll let you know.

<p>Just temporarily - see the problem is if I don't "CHANGE" it
comes up as 24.172 and I don't want to accidentally introduce a
rogue node, so expect will be a workaround for now. This also
means 24.172 is persistently pulled from somewhere, I'll dig
deeper into the pointers received in this thread to find the right
place to change it at.<br>

<p>The new SIMH port appears to allow for a slaved PDP-6, which
I remember seeing on the 9th floor (It was connected to the
MIT AI KA-10). I think they only shared one moby. The last I
heard was that the KL sources to ITS (MC) were lost. Anyway,
if the SIMH KL simulator allows multiple CPU's, then you could
run Tops-10 SMP, which really was a tour de force. Extremely
cool.<br>

<p>Wow. Yes - have to try it, definitely. Also I love the way it
names its interface "ETH-0" :)<br>

I think you're right, but it has been <u>decades</u> since
I last used Tops-10. At WPI, we had a KA-10 running a much
modified 6.03 series monitor that we were quite proud of.
At Marlboro, the project that I was working on (FILE-FINDER,
a database for DUMPER tapes) was quite Tops-20 centric; we
depended on files with holes in them.</p>
<p>I'm unaware of any systems level structured data store in
either Tops-10 or Tops-20 with the exception of the Quasar
failsoft file (QSRFSS, holds queue, print, batch requests
across crashes). I don't find this surprising; if you crash
and corrupt a file with confuration information in it, a
flat ASCII file is whaaay easier to recover than an
specially engineered database. The binary accounting and
error files are sequential and don't count, IMHO.<br>

<div class="moz-cite-prefix">Under Tops-20, we used the
following 'trick' for start-up speed and persisted
configuration. The configuration file was 'compiled' into
binary and directly mapped into memory on start-up.</div>

<li>This was necessary for LPTSPL as it is started up for
jobs, but shut down and put into a quiescent state when
there is nothing left to print. When you have a lot of

noticeable.<br>

<li>I had been thinking about doing this for the Extended

instrumented the start up time and it's in the
milliseconds. Probably would be necessary for a couple
hundred simultaneous small requests.</li>

Tops-10 so I can validate execution.<br>

I've never used Tops-10 as an operator, so I can't answer
most of this, but one question I think I can... <br>
<br>
My understanding is that neither Tops-10, nor TOPS-20 have a
persistent database. Instead you need to have a script that
does all the definitions, and you need to run it at every
boot. But I could be confused about that one. <br>

KLH-10 TOPS-10 noob questions: <br>
<br>
1) At the TOPS-10 boot startup option prompt, I can type
in CHANGE and then set the DECnet address. How do I make
it persist across reboots and not have to do this every
time? <br>
