I worked with them at college.
My first Internet exposure was on my Tandy 1000 TL in 1989, via BBS’ and PC-Link, in full 16 color graphics.
Then 1990 I was at the VT320 terminals. There were both green and amber ones. The amber might have been a Hercules mono emulation on a PC – I don’t remember.
I even got an ancient VT220 at a garage sale once. TINY LITTLE THING it was.
So, sorta yes I also had a Hercules card in an old AT I cobbled together once in the early 1990s, along with a VGA card. Two monitors at once: I was in heaven
