91 9k Turbo needs help

I recently purchased a 91 9000 Turbo. The engine runs great but is very sluggish. I have installed a boost gauge and found that I have absolutely no boost (gauge never goes above 0 psi).
While I was replacing a bad Hooter Valve (Blown Diaphragm)I noticed that the wastegate rod was disconnected from the flapper lever. The lever is rotated 180 degrees from the orientation shown on related web sites.
I tried to rotate the lever by hand, but it would not budge. I took a look at the compressor blades and tried to rotate the impeller by hand, but it would not budge. I did not apply much force, but I would expect it to move even without oil pressure.
I suspect my turbo is toast. It probably seized up and somebody opened up the wastegate so that the turbo would be disabled and the car could be driven (and sold).
Does this diagnosis sound correct?
Is the wastegate wide open in the position described?
How should I procede?
Any suggestions would be greatly appreciated.
