Doing a test pattern is easy - as long as you scan at the right line rate (couple of oscillators, bit of blanking) you get a de-facto valid video signal - that's why they were so popular for test cards etc. - no screen burn, no focus issues, no warm-up time (to speak of), low technical risk etc. What we are talking about here is selecting glyphs from the grid of a NON-TESTCARD monoscope, i.e. an alphanumeric one. This is a much more complex problem. Nick -- You received this message because you are subscribed to the Google Groups "neonixie-l" group. To post to this group, send an email to [email protected].
