I'm not sure that all the smearing and blur is historically accurate for vt220. I still have Wyse WY-150 (IIRC) on my desk and while it has somewhat poor contrast (which seems to be mainly caused by worn out contrast pot, I gotta fix that someday), it has exceptionally crisp display. I remember the same "crispness" feeling from various amber phosphor MDA monitors.
good point - I actually do have a 320 and the topics discussed in the article seem to jive with my experience with it..
but yes, it is very crisp - i think the point of the 'fuzzing' details discussed here is that they actually help the overall clarity (e.g. a 'dithering' sort of effect)
I'm a regular user of the glasstty font + the 'tritty'[1] utility which emulates serial line I/O to create the 'true unix terminal' experience.
Looking forward to the next post!
ps: improved smeary-220 font would be great :b
