I'm pretty sure that's a Link MC5 terminal, which emulates DEC VT220 by default, but that font doesn't seem very VT220ish. https://vt100.net/dec/vt220/glyphs
emulating DEC VT's generally meant the full featureset of DEC ANSI escape sequences for cursor positioning, saving, colors, bold, etc. It would not include emulating fonts.
i googled and found this picture of a Link MC5 screen, though it's monochrome, don't know if they would have changed that.
I think it's just called AT&T PC6300. There are a bunch of variants but I'm somewhat confident it's in that family. The very high x-height and tiny, 45º slash are characteristic.
