- And CC are really going to tell all-and-sundry the internals of their
- dongles to anyone who wished to produce a dongle for their product
- arn't they? Oh Yes of course they will, and what's that pig doing over
- there?
-
- The fact that Impression and Artworks dongles work together isn't
- really surprising. But notice, as you said yourself, they have to be
- in the right order. Now imagine if many companies used dongles, each
- one would have to be tested with every single possible permutation of
- all available dongles in the entire Arc world. Get above 4 and you're
- stuffed. Add to this the total length of dongle tree involved and
- you'd need an extra desk just for dongles (with or without
- dongle-dangles).

- Nope! And yes I've heard of dongle dangles. Just think the connection
- from computer to printer would then have to go through (if 2 dongles
- and a dongle dangle) 5 connections, whoopeee do (I don't think). Just
- think what that does to the signal, given the added bonus of a bit of
- ribbon cable (yuck!). Now add the dongles you're going to get with
- every other RiscOs application who's creator thinks dongles are a good
- idea, what fun.

-
- The reason I said that a group of manufacturers got together was that
- they could share the developement costs. Plus you assume that I meant
- some software method, well I didn't. I was actually refering to a
- hardware method, but which did not involve scrambling the entire
- output of every conceivable output on the back of your computer, or
- having massive trees of badly made dongles.
-
- But it won't happen because it's a lot easier to produce some half
- heated non-solution (like dongles or mixed up cables) than it is to
- come up with a real solution.
