Flight Force Plus....to interface with PC??

[hankey01]

Hi,

I have been happily using my MAME machine for a couple years now...but I know one of these days my terrible hack-job of my keyboard (to interface my controls with the PC) will fall apart...and I am already thinking of a backup plan.

I came across this last night and bought one (haven't had time to try it out).  It is meant for flight sims...but has 9 programmable buttons..and hammerhead connectors...so it can be plugged into the same ps/2 port as the keyboard.

I'm just wondering if anyone has tried this out and had any success hacking it to use as their arcade controls interface?  Would it be possible to piggyback 2 of them to get 18 programmable buttons?
