Well, THE SYSTEM is in the eternal 99.999% done phase, so its time for me to try and sell off some parts I didn't use and make some of that money back.  I have the following items for sale.  First come, first served, pay pal preferred payment.  Shipping will be an additional 4 bucks per order (flat rate, feel free to combine items, everything ships for 4 dollars).  PM me if you are interested in the following:
 All of these items were purchased from Divemaster a little over a year ago.  
IPAC4 Keyboard Interface - $40   [SOLD]
I used it for about 2 weeks before replacing it with a GPWiz40 to get Frontline rotary support.  Works perfect!  Comes with a USB cable.  
Ultimarc Rotary Interface - $21  [SOLD]
Same story as the IPAC.  Again, this has been tested and it works perfectly.  Played quite a few games of Ikari Warriors with it before switching to the GPWiz.  Comes with a USB cable
Happ Top Fire Super Joystick - $20
This was going to be part of my control panel before I realized I needed 2 joystick buttons to play discs of TRON.  I did have it wired up at one point though and it works perfectly.  
Yellow Happ Pushbuttons with cherry microswitches (6 convex competition[SOLD], 2 concave)
50 cents each
