I have a Northgate Omnikey 101 that I bought on ebay. I have the 101's default cable plugged into a DIN5->PS/2 adapter (http://www.amazon.com/gp/product/B000067RBR/ref=oh_aui_detailpage_o01_s00?ie=UTF8&psc=1) which is plugged into a blue cube (http://www.amazon.com/SANOXY-PS2-Keyboard-USB-Adapter/dp/B000BSJFJS/ref=sr_1_1?s=electronics&ie=UTF8&qid=1430277443&sr=1-1&keywords=blue+cube) which is plugged into a USB cable which is in turn plugged in to a USB port on my motherboard.
All of the jumpers on the 101 are set to the down position, which should correspond to AT or PS/2 according to this (see page 5): http://deskthority.net/w/images/3/38/Northgate_OmniKey_Users_Guide_Apr92.pdf
When I plug everything in, nothing happens. None of the lights on the keyboard come on, and none of the keys produce any response. My Model M works just fine when I follow this procedure (minus the jumper switches and DIN5->PS2 adapter).
Is there something I'm missing here, or did I get a defective board?

Sometimes a reboot helps, and try cold- and hot-plugging the final USB.
And perhaps minimize the number of connections and/or try a powered USB hub.

I had a similar situation with my Omnikey keyboard.
In my case... it was the faulty ps/2 cable that came with the keyboard as you refer as 'default ps/2' cable. I ordered a new ps/2 male to ps/2 male cable from ebay. then I used the AT(Din5) to ps/2 adapter you mentioned above. and it was plugged into the ps/2 port of my PC.
It has been working perfectly ever since.
If I were you I would suspect the cable or connector(clean or replace the PS/2 connector in keyboard)
BTW, my jumper setting is same as yours(all down). so it's not jumper setting that causes that.

The default cable for the Northgate Ominkey 101 is PS/2 (din6m) male on the keyboard end and DIN5 male on the PC end. If you bought a PS/2 male to PS/2 male cable and a PS/2 to din5 adapter, how did you then connect the din5 end to your PC's PS/2 port? It seems like you would have needed another adapter.
Do I really need to buy PS2 (din6M)->PS2 (din6M) + din6F->din5M + din5F->din6M to use this with my blue cube and a USB cable?

That cable stuff is weird.
If you have a spare cable (I used a beige IBM rubber dome cable with ground wire) you can bypass the original stuff and make an attached PS/2 cable. I cut 2 pieces of plastic to make an escutcheon for the hole that used to be the female mini-DIN6 socket, and attached it with M2x8 screws and nuts from a Model M bolt mod.

Based on the above, you were able to get it working using a straight PS/2 male->male cable plus a PS/2 to USB adapter. I have read other people on GH insist that the Northgate Omnikey 101 will absolutely not work with a straight PS/2 cable, even though the port on the keyboard looks like PS/2.
You are using a Northgate Omnikey 101, correct?
Also :confused: at those cable prices.

I have tried it with more than one keyboard and more than one cable, but perhaps I simply had bad gear.
If off-the-shelf cables work properly, that is great news.

I am sorry to confuse you. my memory failed me LOL. I got confused myself because I use Focus 2001 sometimes. so there was no need for a Din5 to Din6 adapter for Omnikey. It was only for Focus keyboard.
I am typing this comment with my OmniKey 101 using just PS2 M/M Keyboard Cable(din6 and male on both end. a plain straight cable).
I ordered it from ebay (I think I paid about $5 for 10ft cable).
I have no idea why some people say that straight ps/2 cable doesn't work... because I use it everyday :) so... there is nothing but a male ps/2 cable between my Omnikey 101 keyboard and PC(ps/2 port).
I think that it should work with a 'Good' ps/2 to USB adapter(they are not all equal quality).

Good to know, thanks. I'll just pick up a cheap PS/2 cable on Monoprice.

I received my Monoprice PS/2 cable today and can confirm that the following works fine:
Northgate Omnikey 101 -> PS/2 Male:Male cable -> blue cube -> USB cable -> PC USB port

I'm late to respond and the ship has long since sailed, but overdriver has already confirmed that straight ps2 cables work with Omnikeys. I don't actually have an Omnikey 101 -- I've got one Ultra T and two Ultras (I prefer the big iron) -- but I don't know any reason to think that different Omnikeys require different cables. I figure it's best to minimize the number of cables and connections.
