I had a feeling the later TKs read TK50. I read it on on of HP's DLT
compatibility docs but couldn't remember if it was TK50 or TK70 that
was the oldest compatible format. I have a SCSI-II DLT4000 drive (TK88
or 89??) and I know that doesn't read any old TK tapes, only DLT1,2
etc.
Yes, it should.

The upside of this solution is that it's relatively portable though - I'd love to have a DECNET stack on my OS X boxes, for example (in fact as mentioned before latd DOES work on OS X as it's kinda implemented in a similar way)..
Which reminds me that I should work on/write a replacement lat suite, since the version out there today have some bugs. I've tried looking at it, but I'm just not into C++, or able to penetrate the code enough.
Anyway, using the lat client program supplied, connecting to RSX, it seems like it breaks the lat protocol sometimes. And unfortunately, the RSX LAT server have a bug triggered by the free lat implementation, in which the session gets lost, and as a result some memory is lost in RSX. This eventually cause the system to crash because no more free memory is available in DECnet.

I take it TK50 tapes won't read in a later drive?
They will. TK70 and TK85 (if I remember right) can both read TK50.
You also have the TZ30 (I think the name is), which is a TK50
compatible, but smaller drive, with SCSI.

There is a DECnet stack for DOS and Windows in the Pathworks V5 or V6

Windows NT4. Then the Pathworks32 kit was released and that could be

sure.
Is this the same as DECnet-DOS? I ran that a long time ago. Does
anyone have a copy? It included drivers for that weird DEC ISA Ethernet
card, the DEPCA, which was a full-length 8-bit board that also included
(strangely) a mouse interface.
If not exactly the same, but a newer (and possibly enhanced) version. I
didn't deal with the PCSA versions (< V4.1) so I don't know about them.
Unfortunately I don't have the V4.1 either. Just the V5 and V6, which
were distributed on CD's.
Anyhow, the V5 or V6 DECnet stack should work on MS-DOS V5 and newer. I
don't remember if it was possible to install on older DOS versions. The
client medium has the supported adapter drivers (like DEPCA) included.
Neat!
Yes, indeed, I also have one or two DEPCA's somewhere. I think the mouse
port was meant for the DEC workstation mouse ("hockey puck") as PC mice
were serial port attached.
Yes, there were drivers in some packages that recognized those puck
mice with the DEPCA's controller. I ran Ventura Publisher (the GEM
version, pre-Windows port, under DOS 3.3) that way for a long time. It
worked well.

TK70 drives can read, but not write, TK50 tapes. I have several TK70
drives as well...that is my backup plan. (no pun intended! ;))
