Title: Marconi AT02
Post by: nubbinator on Mon, 17 November 2014, 22:19:00
No clue what switches it has since I don't think I've ever seen someone with one of these, but other Marconi boards have been Magnetic Valve switches.  Fun if you're into vintage military stuff, but kind of pricey at $140.

Correction: it is not pricey. It is drop dead cheap.

Location is in Poland

Shipping is free

Weight of this thing is probably in line with other military metal keyboards aka heavily armored

When you think about it, seller is probably getting no more than $40.

Not to burst your bubble but here is a cheaper one with a bit of research:

$44+49 shipping so around 40-50 dollars cheaper if someone has to buy one of these. I am curious on what switch it is though.

Are you sure you're not confusing it with the gilbarco marconi which used either keytronic reed switches or ITW magnetic valve?

I think this has a "bad-to-type-on" kind of switch and certainly neither of the above.

Those connectors like they have internally though are like $100+

Like I said, I have no clue what this has switch wise.  I just know some of the more modern Marconi boards have the ITW Magnetic Valve switches so I included that segment.  For all I know, this uses the bastard step-child of MY and rubber popper toys for switches.

Trust the full power of geekdom to find these obscure things. But what surprises me most, is that the weight is only 2.5kg as given by the seller that Minh found. Barely heavier than an SSK? Sounds like this thing is made of aluminium.

Or magnesium. Lots of military things were. Then there is the possability that they just wrote the weight down wrong.

12.5kg, I believe. That casing looks like a huge chunk of steel.

you mean this guy?
(http://i.ebayimg.com/00/s/NzEzWDk1MA==/z/E7sAAOxygPtSvFI8/$_57.JPG)

It's a circular mil-spec connector.
http://www.mouser.com/Connectors/MIL-Spec-MIL-Type/Circular-MIL-Spec-Connectors/Circular-MIL-Spec-Connector/_/N-cigvb/

On the alphameric keyboard i have it outputs two PS/2 connections. Shell size 20 maybe? hard to say for sure without a better picture or part number.

Somea re quite cheap (only $30 or $40) but ones that connect to mine are $90 - $120 :(
