VGASpeed v1.0, VIZ v4.12d, Zeno v1.3 and TheFast v1.06 are old programs,
and they all have a cursor bug (the bug in TheFast is quite different).
In some operations there are programs faster than Zeno v1.73, but this
speed derives from buggy routines (that are faster because they don't
update cursor position) and/or from the fact that they don't handle
multi-pages (and so they execute less operations than Zeno). But multi-
page is required by some programs, that otherwise will crash; Zeno v1.73
supports multi-pages even in 80x43 & 80x50 modes, while other accelerators
(except VIZ v4.12d) mess-up video output and often hang the machine if you
use a page different from 0. Zeno v1.73 is fully compatible with any
text-based program.
