Yes, I had a 3270 AT/GX with the 5379 color display and simply loved it 
as it gave me lots of 80 column, 50 row 3270 sessions (4 on the 3270 
adapter, 4 on the Token-Ring adapter) and the screen refreshes were FAST 
- a System Programmer's dream.  The powers that be dropped a 8580-A31 
with 8514 display and 8514/A adapter running OS/2 EE and told me to use 
it instead of my old "clunker".  I tried it, found it slow, and kept 
running my 3270 AT/GX until OS/2 Warp 3 came out and I finally put the 
3270 AT/GX to bed.  By then we were up to 9590-DLG units with XGA 
graphics, which was "good enough", even though the 3270 AT/GX still had 
the edge on 3270 screen updates.
