Do you have an external, powered SCSI hard drive or drive case?

The first thing I would try (as it's the least destructive) is to see if the IIci+Rocket will boot from an external drive. Either clone the startup disk / system folder to the external, or remove the internal HD altogether and put it in the external case. Then, unplug the power leads to the floppy and internal HD (if it's still there), power up the external drive, and boot.

If that works, then it shows that the IIci PS has enough grunt to run the logic board + Rocket, so you can then hook up the LC supply to run the floppy + HD and be done :)

I may have access to NuBus connectors at my local surplus store (I'm going to go check today.)
Oooh }:) How many, and at what price?

What about soldering a molex connector directly to the voltage pins
AND at least one ground/earth.

on the card, disabling the pins underneath
How?

so they don't connect to the motherboard, then just plug it directly into the LC power supply?
Where does the added Nubus connector come in here? Does it sit between the Rocket and the motherboard Nubus socket? If so, will you still be able to close the case with the added height on the Rocket?

I do like the idea of a self-powering Rocket mind you :)
