Forgot this bit earlier...yes. The bits are shifted into place and latched
until the next value is available. There are 89 lights IIRC, and 96 bits
of shift register. The 26 switches are embedded in a 32 bit input shift
register. Since the shift registers move quite fast, it completely
swamps the lamps' ability to change brightness. Unlike the VGA display,
I haven't observed any "beat frequency" artifacts.

I've got
the code running FOCAL and other stuff in John's configuration,
and the 8/i front panel is pretty much working in that configuration.
How is it
attached? Shift registers?
