Not that I need one for my TT, just sharing this find.
While Googling, found this that may be of use, especially TT users looking to get a SCSI SSD device. Looks like they do replacement of old SCSI devices including 50 pins SCSI. http://redrocktech.com/products/scsi-drives
They do not have prices on their site, so I suspect it not to be cheap.
