Anyone got spare MMJ-MMJ console cables?

But my point is that the tools and plugs are findable I have a Paladin crimper with interchangeable dies for many different types of connectors and I cannot see how you "turn around" the MMJ die. Same goes for my Tyco/AMP crimper...ain't no turnin' those dies around. BTW this place has MMJ connectors in stock, at $14 per box of 100: http://www.computercablestore.com//Modular_Connectors_RJ1112_PID2061.aspx I just got some from them about a week ago; haven't used any of them yet but they look ok at first glance. -Dave -- Dave McGuire, AK4HZ New Kensington, PA

DECnet/DOS, was Re: [HECnet] DECnet and Windows NT?

I believe (but am not certain, can anyone clarify?) that it is what grew into Pathworks. We used it extensively in our network back at the early 90's. IIRC the name evolution was DECnet/DOS => PCSA => PATHWORKS. The main problem with the DOS version was it ate a lot of "real" memory (about 300KB if my memory does not betray me). That left a very small space for applications... On the nice side, it came with an EDT compatible editor (SEDT... I miss it :)) and a XServer for DOS which worked nicely with DECWindows. That was the reason the puck mouse interface was in the LAN card. We had a DEC-centric office system back in those days. ALL-IN-1 running in the VAXen and WPS-DOS running in the peecees for word processing (BTW, does anyone have a WPS-DOS disk set arount? ;)). 20/20 for spreadsheet at both sides. And TEAMDATA to allow the end users to browse the databases. We bought 3300s for the remote offices. 3 of them I think. We linked those to our main site using 1200bps point-to-point lines with DECRouters at each side (1 port models at the remote end, a 4 port one at our central office). One of those 3300s ended at my home, and is now called BITXO2 :). Nice! The DECnet/DOS I ran didn't have an editor or an X server; the one you're talking about must've been a bit later than mine. Neat stuff. If I can find my DEPCA board, and the software, I will bring it up in an AT-style box of some sort, just for the heck of it. :) -Dave -- Dave McGuire, AK4HZ New Kensington, PA

I thought I've seen straight-through version also, which you can make by ha= ving one of the two connectors "upside down". You might have seen that but it wouldn't work with the myriad MMJ to 25pin and 9pin connectors that DEC had floating about. I believe, if you took a look, that this is all detailed in the OpenVMS FAQ. Stephen Hoffman keeps one of the most up-to-date OpenVMS FAQs (probably because he compiled most of it while he was still in OpenVMS Eng.) on his web site. http://labs.hoffmanlabs.com/vmsfaq/vmsfaq.html MMJ specifics: http://labs.hoffmanlabs.com/vmsfaq/vmsfaq_025.html#index_x_1818 -- VAXman- A Bored Certified VMS Kernel Mode Hacker VAXman(at)TMESIS(dot)ORG Well I speak to machines with the voice of humanity.

I can do other terminations such as RJ45 and DB9 but they are more expensive, especially if they require cross-wiring. I don't think that's unreasonable given the investment I made to in equipment and parts and the time it takes me to make and test each cable. You'll be a millyonaire by christmas I tell ya... Yes, I will, but which Christmas is anyone's guess. Current estimates are around 2347... if the Yeti's don't get me first. ;) -- Mark Benson http://DECtec.info Twitter: @DECtecInfo HECnet: STAR69::MARK Online Resource & Mailing List for DEC Enthusiasts.
