I need both a cable AND on the other end I also need a detachable 25-pin Digital adapter that connects to the DEC un-centered plug pin. See 2-11 in MicoVAX 3100 and VAXserver 3100 Owner's manual.
Yes I could make a cable, but I'd prefer the DEC cable or clone commercially mass produced if possible.

Just for VCF?

DEC MMJ connector. Great idea, PITA years later. :)

I can look and see if I have MMJ parts I could loan. That said, does anyone have an MMJ crimper they could bring to VCF? And I good source for the connectors themselves? I have a 1000' spool of "silver satin" 6-wire cable to share, and places where the authentic DEC parts aren't important to me. -- Jameel Akari

I am looking to buy and have shipped to my home, I need to have another cable to help me set up the cluster machines for VCF E. I will take some at VCF E, but before I that I need at least one. Will pay $$. -- @ BillDeg: Web: vintagecomputer.net Twitter: @billdeg <https://twitter.com/billdeg> Youtube: @billdeg <https://www.youtube.com/user/billdeg> Unauthorized Bio <http://www.vintagecomputer.net/readme.cfm>

Yes and yes. I brought mine last year (have dies for MMJ and standard 8p8c as well as standard 6p6c and various wire terminal crimpers), and will bring again. I have pretty full bags of MMJ and both solid and stranded 8p8c plugs. For the connectors, they're actually surprisingly easy to come across. For example: http://www.pacificcable.com/Picture_Page.asp?DataName=MMJ or http://www.neobits.com/pan_pacific_pt_066dec_rj_11_mmj_dec_plugs_qty_100_p39... (I've used Pacific, but the other one is probably just as good for $10 less). If you have a Paladin Crimp-All 8000 frame (and you should, because it's a great tool), the Paladin die for MMJ is 2067. - Dave

I've purchased them from L-com, they're more expensive there (wish I'd known about these other two vendors, but my last buy was a year ago). http://search.l-com.com/search?keywords=mmj Just another option in case the others run out. Interestingly, they also carry new DE9<->MMJ adapters. -Dave -- Dave McGuire, AK4HZ New Kensington, PA
Thanks for the info http://www.pacificcable.com/Picture_Page.asp?DataName=H8571-J plus they have a MMJ-To-MMJ-Cable $14 plus ship Bill -- @ BillDeg: Web: vintagecomputer.net Twitter: @billdeg <https://twitter.com/billdeg> Youtube: @billdeg <https://www.youtube.com/user/billdeg> Unauthorized Bio <http://www.vintagecomputer.net/readme.cfm>

Excellent. I only need to make up a few cables, and having found the Pacific Cable source earlier, don't really want to buy 100 of them. 30-585 is the Ideal Crimpmaster MMJ/DECconnect die, of which there seems to be exactly one on eBay, bundled with three other dies I already have. I'll skip that. I should figure/find out mappings from MMJ RS-232 to Cisco/Sun and maybe Xyplex RJ-45 serial. If I don't need to switch back and forth between D-sub and modular and back again, I'd rather not, even if it means I'm making a one-off special unicorn cable. -- Jameel Akari

If this would be helpful...buy the 100, use whatever you need, and I will purchase your excess. Let me know.

That's the one I have. Works a treat. -Dave -- Dave McGuire, AK4HZ New Kensington, PA

If you Google "DEC MMJ plugs", the shopping links contain some places where you can get onesie-twosies for .50 each, if that's what you want.

Maybe. The Paladin tool is an excellent one, though, and their MMJ die is still made and available through Amazon for like $25.

That's what I do; I use a Cyclades pinout DB25-8p8c adaptor and just make an 8p8c->MMJ cable with 6-conductor silver satin. The Cyclades pinout works very well for MMJ; all the conductors are in order, and you only have to snip/bend down one of them. And if, like me, you have a 48-port Cyclades terminal server, that's a really useful cable to have a lot of. - Dave

A very useful device in making less-than-8-wire custom * -> RJ45 is the Platinum Tools EZ-RJ45 -- the little tunnels for the conductors go all the way through the end of the RJ45 housing, so you can strip your cable back really far and poke each individual wire through one at a time. Much less fiddly than trying to hold it just right! The special Platinum Tools crimper shears the excess wire off when it crimps, but I imagine you could use a standard crimper and just clip the wires yourself. I've made a bunch of RJ11/RJ12 -> RJ45 cables this way. Gets around those not-quite-standard APC console cables! Thanks, Jonathan
