For those not wanting to chase the link, it says:
Filer: G, S, N, L, R, C, T, D, Q [1.1]
Don't you remember? This was the security mechanism.
Must have been the apple {likely ti99 too} version without
the 80col card. On a S100 Z80 crage using an H19 it
was far better. I had the chance to compare the two and
UCSD was marginal with 40 char, somewhat better at 64
and seemed like a different animal with 80 (or more) col.
