Question Adding a hard drive to Hoei Precision Microboards Disc Duplicator ?

I bought a Microboards disc duplicator, circa 2007, with 11 IDE DVD/RW drives. There was an option to add a 500 gig hard drive. The HOEI PRECISION OMNI Rev 1.03 board in it has an unused 50 pin dual row connector I'm pretty certain is SCSI.

There's a row of 4 DIP switches, nothing is marked on the board with any useful information. Microboards did send me the final firmware update for it, based on its serial number. Unfortunately they have no technical info available on what has to be done to add the hard drive, which was the difference between the CopyWriter and CopyWriter Pro models. I found nothing useful on old versions of their website on the web archive.

From some googling it looks like most of these disc duplicators sold by various companies used boards made by Hoei Precision, with firmware customized to display different names on startup and in the version check.

If someone has a duplicator with this same board and a hard drive, I'd love to see how it's set up. Even if it's not the same board but is made by Hoei and the drive is SCSI, and it has the 4 switches, I suspect the settings are applicable.

What could be an issue is if there's a firmware difference and there's just no HDD support in mine.

One of the burners doesn't want to write, though it did do a full erase of a CD/RW. I'm tempted to try connecting an IDE hard drive in its place and see what it does.

I only paid $10 for it at a thrift store.

That would be my guess too. Ultra SCSI 50-way, not Ultra Wide SCSI (or LVD) 68-way. I still have a few SCSI drives but have no idea if they're still working.

It's vaguely possible the connectors designed for use with optical drives are ATAPI and might not handle an IDE hard disk.

I've not used a customised disc duplicator rig and it's been so long since I built IDE-only systems or SCSI RAID systems, I'm starting to forget all the subtle nuances.
