SCSI indeed. Attached to an old G4 tower. And a monitor, Barco, dating back to 1998, which is probably as heavy as the Screen itself!
I have made a newby scan with the Epson 4490 and Screen, but the latter scan may be too large to be acceptable to Snapixel, or in any case it refuses to be uploaded. Which is a shame because the difference is mind blowing. The Screen is SOOOO much better, not just in sharpness, but foremost in detail and tonality.
But I'm still relearning, having been out of it all for almost 15 years due to circumstances. (I'm seeing some pictures for the first time, having shot them 10-18 years ago without ever printing them. I wish I knew how I shot some of those.)
Edit: here is a screen shot, with the dirty scans (note: dust removal and PP not applied). The left is the Screen Cezanne, the right is the Epson at maximum dpi. The result speaks for itself. It is a crop of about 125-150%.
