since everyone has a computer later than the towers of the 1990's how about adding a IEEE {firewire 800} to usb/usb-c connector box to the accessory lineup, so we can use these older camera backs, or at least have the ability to download the images of the cards and convert from 3F/3Fr files to TIFF or DNG so photoshop can touch it.
