Why the heck are there two Part numbers? I've found in my boxes an old Chipset resqued from an old PC adapter, it contains a Am7992. I'll solder in a socket and will try... Could please someone look at the PCB and find out which chip is soldered in? They are at least pin comatible.. Regards, Holm -- Technik Service u.

I owuld gues a lot of people could solder the other end of the cable to a DE9, DB25, or whatever, it's getting and crimping the MMJ that is the problem. So a long-issh cable (3m or so) with an MMJ on one end only would be useful. The purchaser cuts it to length and solders the right conenctor on the other end. My cheap-ish Multicomp (Farnell own-brand) crimp tool claims to do 'DEC plugs'. I've never tried it, and have no idea which make of MMJ it likes. It has woreked fine on every 4p4c, 6p4c, 6p6c aed 8p8c I've thrown at it though. -tony

As far as interchangeable die crimp tools go, I think these are probably the best out there. It will also accept dies from a number of different manufacturers including Ideal and Greenlee. Another really nice tool is the GMP modular plug presser. These use a single die instead of the more common two-part die sets. The tool itself is one of the more expensive ones, but they can be had for cheap if you watch the surplus market. It does carry a lifetime warranty though. http://gmptools.com/nf/index_MPP.htm Those prices are pretty good. At the time I bought 6P6C to DE-9 adapters, rewirable MMJ to DE-9 adapters were expensive and had become very hard to find. 'DE-9', not 'DB-9'...

[If you are one of the handful of people who already know, don't give it away.] Those NOS H8571-J rev B adapters are actually available FS/FT [absolutely no resellers!], but they aren't cheap (I used to sell them for $30 in my eBay store). I literally spent a small fortune on them to keep them away For the MicroVAX II end of the cable, for a MMJ cable you would want a DEC H8571-B. http://strudel (dot) ignorelist (dot) com/~tothwolf/classiccmp/H8571-B.jpg http://strudel (dot) ignorelist (dot) com/~tothwolf/classiccmp/H8571-B_naked.jpg [That 'naked' H8571-B was already sans it's outer plastic shell when I obtained it mixed in with some other random DEC parts.

I made this as a one-off cable long before I was ever able to obtain proper H8571-B and H8571-J MMJ adapters. It worked great, but less than 6 months later I got my hands on my first H8571-B and then maybe a year or so later my first H8571-J.

On Sun, 12 Aug 2012, Tony Duell wrote: That's why I first began making those MMJ (6P6C offset) to 6P6C standard plug cables. People asked me if I could make cables that could be used with 6P6C to DE-9 or DB-25 rewirable adapters. I later had enough demand for them that I began pre-wiring 6P6C DE-9 adapters as H8751-J work-alike adapters and pairing them up with a cable. These were moderately cheap for me to make when buying the materials in bulk and they sold for $15-20 in my eBay store (which covered my costs, including the stuff people often overlook such as the eBay listing fees and shipping supplies...that is until eBay raised their fees through the roof). I actually had a hard time keeping up with initial demand for those cables and shipped them all over the world. Note that those DE-9 connectors used crimped pins (AMP) and not soldered/spliced wires. They are a pain to assemble (even with AMP's own d-sub pin tooling), but I had zero complaints or returns for defects or bad connections. http://strudel (dot) ignorelist (dot) com/~tothwolf/classiccmp/H8571-J_BC16E_work_alike.jpg http://strudel (dot) ignorelist (dot) com/~tothwolf/classiccmp/H8571-J_BC16E_work_alike_unfinished_1.jpg http://strudel (dot) ignorelist (dot) com/~tothwolf/classiccmp/H8571-J_BC16E_work_alike_unfinished_2.jpg Even without seeing it, I would say with 99% certainty that your crimp tool handles the WE/SS variety and not the AMP/Tyco type plugs. Most all the "generic" plugs on the market use the WE/SS die nest form, so unless someone is making these kinds of cables regularly, they may never even run across the AMP type plugs. That said, AMP plugs have some benefits (such as the double strain reliefs on the 8P8C plugs) and there are tons of their connectors on the surplus market. You can also be certain that when they say they have 50 microns of gold plating over nickel, over phosphor bronze, that that's what you are really getting. Some of the really cheap Chinese-made plugs on the other hand are just gold flash over brass, and you can pick these out pretty easily when you unplug a cable and find that the contacts have corroded green right through the gold plating. This is why I'm so picky when it comes to using decent quality modular plugs and contacts, even though to some people it might seem as though I'm being a little _too_ picky ;)

On Mon, 13 Aug 2012, Tony Duell wrote: 99% of the people who wanted a DE-9 adapter wanted a way to use a PC as a terminal/console for a system that had a MMJ connector. A lot of people were using laptops. Soldered adapters wouldn't have been of any benefit to those types of end-users since they needed adapters for that one specific application. Even with crimped pins, it isn't hard to change an adapter if you need to later, so long as you have an insertion-extraction tool for the pins. Using solder-type DE-9 connectors would have been more expensive and far more time consuming to assemble, especially in any sort of volume. I didn't have any complains with the cables I made but if someone had asked I could have made up a modular cable with only one end terminated.
