[rescue] Various machines for sale

[Lionel Peterson]

SCSI scanners were all the rage in early Mac era as I recall - they used big "centronics" style printer cables.

Weren't early sun laser printers SCSI?

NVMe has a much, much greater speed than anything you can hang off a SAS/SCSI connector - PCIe Gen 5, 4 channel devices are on sale at Microcenter today...
