Nope.. active components not only didn't have them, can't even *order* them! DB37 looks like a serial cable (plain ol' pins and holes) except it has 37 pins. The usual parallel cable is a DB25, serial is DB9. So not, SCSI, not printer, not parallel.
Honestly, I don't know WHAT the **** a DB37 was used for. I can get it online, but I preferred to, uh, get it for free.
