Yep. That's it. Thanks for remembering. We were still using one when I
left my previous position in 1995 with a 3090 400E processor.

I have watched that nice video, bringing back memories of those 3800,
3380, 3090, 3420 and such animals.
But what the <four letter word> is a 'GRS Control Unit'?
Searches on IBM webpages (and history webpages) gave me just all
[useless] info about GRS or CONTROL or UNIT, but not specific details
about that device.
Anyone having a clue what device is it? Is it the grandfather of the
XCF and such things?
TIA!
