SCSI 80pin is very hard to come by these days I think.
You may have to buy an adapter to convert it to 68 pin or 50 pin then try that with a USB to SCSI adapter (which would like require external housing and power for the drive as well) or with a modern internal SCSI controller card which seem to sell for 100 to 200 bucks.
I see an 80 to 50 pin adapter here: http://item.express.ebay.com/Computers-Networking_Computer-Components_Drives-Storage_New-SCA-SCA2-80-Pin-to-50-Pin-ACTIVE-TERMINATOR-Adapter_W0QQitemZ110004444239QQihZ001QQptdnZDrivesQ20Q26Q20StorageQQddnZComputersQ20Q26Q20NetworkingQQadnZComputerQ20ComponentsQQcmdZExpressItem
I am only theorizing and have no idea if that would actually work but unless you can find an old 80 pin scsi controller card, cables, and terminator...
