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)..

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. The TK85 can read TK50s? I didn't know that! If that's the case, it's likely that the TF85 (DSSI version) may as well, and I have one of those. That may be one more option to get my huge pile of TK50s read. -Dave -- Dave McGuire, AK4HZ New Kensington, PA

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. -Dave -- Dave McGuire, AK4HZ New Kensington, PA

There are copies of WordPerfect for Solaris currently available on ebay UK. I asked the question about WordPerfect for VMS on comp.os.vms - turns out there is a company still selling it. However, when I mentioned I was a hobbyist the communications went silent. Mark.

There was even a version for SunOS, with a fairly respectable WYSIWYG GUI. I used that quite a bit Back In The Day(tm). I think I still have it somewhere. Those binaries will likely run under current Solaris on UltraSPARC; I've been amazed at the degree of both architectural and ABI compatibility between BSD-based SunOS 4 and SysV-based Solaris. -Dave -- Dave McGuire, AK4HZ New Kensington, PA

Easy to fix if you are comfortable with a screw driver. I've had one or two TK50 go bad in other ways, but in my experience it's pretty uncommon for them to really break. It's almost always that pickup. Let me know if you need help understanding that. The "tongue"? Been fixing that problem for years. At one point I ordered a box of (I think) ten of those while DEC was still selling them as repair parts, but they're all gone now. Eventually the little grabber end breaks off due to plastic fatigue. The drives whose tongues are intact simply refuse to read and cause device timeouts. I have at least 7 or 8 in that condition, with no obvious mechanical flaws. I haven't dug into them very deeply.
