Either use messages over the appletalk of what to display... or treat each
computer 'up' the chain like a dumb mechanical counter....
call the boxes H1, H2, M1, M2, S1, S2.... S2 tells the time... when it
rolls over to
zero it sends a 'tick' to S1... S1 knows its 'position', so when it
rolls over from 5
to 0, it sends a tick to M2.... and up the 'ticking' goes.
Either way would be 'fun' :-)

Thanks for the vote of support :). I think most of the code should be
dead simple but I'm not sure how the time-sync networking portion's
going to go. I also need to pick up some serial Appletalk cabling;
the SEs and the SE/30s have ethernet cards, but the Classics are
unexpandable and thus do not. Maybe I can just find some more SEs to
use :). Hi all --
I'm looking to do a bit of (simple) development targeting a 68k Mac (or
two, or three, or six...) and since I've never done any programming
on a
Mac before I'm curious if anyone out there has any recommendations
for a
development environment to use or to avoid. I'd prefer C/C++, but I'm
flexible :). I'd like to be able to run my code on a Mac Classic/SE
(so
I need to be able to compile to 68000 code) but I'll be doing the
development itself on a IIfx.
In case you're interested, I'm writing the software to build a clock of
sorts out of a set of six "classic" form factor Macs I have lying
around
(two Classics, two SEs and two SE/30s). Each computer will display one
digit of the time, and will be synchronized over an Appletalk
network to
keep the system times in sync. Or so goes the theory. Figure it'll be
a fun display to have set up, and a somewhat interesting use for some
otherwise-idle Macintosh hardware :).
That is a really cool idea, which I like a lot.
I am sure you're aware of it, but it instantly brought to mind the
story of Jamie Zawinski's Dali clock and getting it running on various
elderly Macs...

I hope to get most of the work done this weekend, assuming nothing
interrupts me... ha ha ha.
And I have a copy of the original Mac Dali clock on one of my macs...
somewhere :).
