Every time I thought about it, or even started, I gave up, because there 
aren't simply enough people who would buy such a thing. The prices for 
an old working Qbus SCSI controller are low enough, to just wait until 
you get one on ebay for a decent price.

So all of my machines have SCSI in the meantime, and the headache of 
making my own is gone ;-)
