My eBay "best offer" on the hose came through so it's effectively all tooled up. I still may want to replace the 'bojack' tools with correct ones at some point.
In trying to find information about this thing, I came across photos of a Discovery Advantage (see URL below) that has a trapezoidal adapter that goes between the cord and where the power plug-in is on mine to provide a second plug-in for a SideKick. It looks like it could be a plug-n-play adapter. If so, it might be cool to find one and retrofit mine but I don't know whether I'm really into re-wiring the machine if it isn't.
I went ahead and took a few photos for your enjoyment, with and without the accessories onboard.
