<p>What issues had you encountered talking to Tops-20??</p>
<p>If you are using the SIMH emulator for a KS processor, then the
latest version of Tops-20 you can run is 4.2, which I believe will
do Phase III. Since there was never any Ethernet adapter for the
KS (it was a massbus device), I believe you must speak DDCMP,
which we used with KMC's, which would do 56Kbs. There was a
slower adaptor for 9.6Kbs, but the name escapes me at the moment.</p>
<p>I've had little trouble with Tops-20 V7 DECnet; that is, once I
got it to working. When I was modifying FAL/DAP to accept
anonymous transfers, I and and others beat on it quite a lot to
wring the bugs out. These regression tests were against another
20, RSX 11M+ (or whatever MIM:: is running) and a couple of
Vaxen. The operating system level code was robust; no crashes.</p>
<p>We found some interesting bugs; I think my favorite was RSX
wanting all capital letters for months and Tops-20 sending
capitalized months, so file dates got messed up. There were
others, but they took some effort to remediate; so, not so
favorite...<br>

has been built to be portable (it is in C). I have it
running on Windows, Debian and FreeBSD. I have not tried on
VMS, but I did do a partial port to VAXELN. I don’t foresee
great difficulties getting it to run on VMS. It looks like I
may have done some partial VMS work, but it has been a while
since I looked. I could look into reviving/continuing that
if there is interest.<o:p></o:p></span></p>

won’t talk to TOPS10/20, yet. I started something on that
too if I remember correctly, I did build a DDCMP

foundered on just getting DECnet running on TOPS20 on SIMH,
I did some work with Mark Pizzolato and Timothe Litt to
build a KDP emulation, but I struggled to keep up with them
and gave up in the end. I am not sure where that went.<o:p></o:p></span></p>
