MKULTRA, I'm pretty sure the winkeyless kit is what you are looking for.
That'll work with Poker etc?
Please someone correct me if I am wrong, but this is what I have learned from this wonderful forum:
I'm pretty sure that the Poker uses standard ANSI key layout (1.25 mods, 6.25 spacebar) on the bottom row. I don't think you need a tsangan for it. So it would look like this:
Bottom row: 1.25 - 1.25 - 1.25 - 6.25 spacebar - 1.25 - 1.25 - 1.25 - 1.25
The Winkeyless Mods that come with the Toxic Base set should serve the same purpose that a tsangan add on would:
Bottom row: 1.5 - 1 - 1.5 - 7x space bar - 1.5 - 1 - 1.5
stepped off-center stemmed caps lock
The latter is usually only needed for some Cherry keyboards and Korean custom boards. Some people will also build the Phantom and GH60 to use the tsangan-style bottom row (myself included)
Bottom line is that all of the above keys look to be included in the Toxic Base Set, so you don't need anything extra unless you want the TOX color mods. The ones included with the base set look to be GX only
