Hey~ Wanna see some tech gore? 
Here's the final result of installing my tape drive into the server. For something that looks cobbled together from an enterprise e-waste bin, I think it turned out great!
Yes, I made a custom blanking plate that allows the fiber cables to run outside of the case. I know this looks incredibly sketchy, but I used a file so there's no burrs or sharp edges at least.
I also finally got the RS422 dongle tonight, which I wired up using part of the control harness from the tape library sled. Using moserial and the instructions provided from the github I found, I was able to configure the correct baud rate and parameters to send and receive hex code from the tape drive.
If everything works as expected, you should get "IBM" as the reply for sending hex 00, which I finally did after doing enough tweaking. Then I sent the magic hex string to tell the drive to switch to standalone mode.
Initially I thought it didn't work, but within seconds the drive rebooted itself and successful initialized! I was even getting green status lights and das blinkenlights from the HBA now! Yaaaay!
Then I grabbed one of my tapes and inserted it, which the drive was more than happy to load and spool up. I'd say it's working now, hehe~
Now comes the next step of this endeavor. Getting the server to send and receive data from the drive, hehe~
