<p>I have heard of three 'standard' (I.E., DEC supported) front ends
for the 20, <br>
</p>
<ol>
<li>RSX-20F for the terminals and KL management,<br>
</li>
<li>MCB for DECnet and <br>
</li>
<li>DN60 for IBM RJE workstations (which I maintained at Columbia.</li>
</ol>
I do know of some hacked front ends:
<ol>
<li>Case Western had a second front end running terminals (that's
right two front ends with DH11's). How they got that many users
signed on without the system melting into a puddle of bits is
beyond me.</li>
<li>MIT Chaos on a KL uses a DN20 for the Ethernet communications
(an NI not being available at the time)</li>
</ol>
I never heard of COPOS/11, either but I don't get out much...
Anybody else?<br>

And what the heck is COPOS/11?? I see that is says TOPS-20 front end, but
I thought TOPS20 used the same RSX20F as TOPS10.
And DTF/MVS? Is that the IBM OS MVS?
