Old Centronics-type 50-pin SCSI terminator! (Unfair advantage though: I'm a Mac guy.)
I still have a couple of those in a drawer somewhere. In fact, I've still got one on the hard drive attached to my Mac Plus, and one on the last device in the SCSI chain attached to the Quadra.
When I look at the SCSI-2 terminator on the back of my SparcStation at work, I sigh and say "In my day, SCSI terminator were FAT and UGLY and the CLIPPED ONTO THE COMPUTER with these flimsy pieces of WIRE! We didn't have your fancy-schmancy QUICK-RELEASE BUTTONS, and WEEEEEEEEEE LIKED IT!"
I have tons of those. SCSI was a pain in the ass. But, sadly, these past couple of weeks I've been having more trouble with Firewire than I ever had with SCSI. It's compounded by the fact that I understood SCSI pretty well and had lots of tools to troubleshoot it. My Firewire devices just work or they don't, and there's nothing I can do to change it. Very frustrating.
OK, it's official. Most of my readers are geeks. :-)
I'm trying hard to cut back, but some memories are just too difficult to supress.
If it makes you feel any better, I don't know what the HELL you're talking about! :)
