Re: TI-H: A Virtual Hub: Interlink



there are a few better ways to do this.  First off, the crash control is a nice idea, but very Ethernet-like.  Ehternet is fine, but these link portss hit around 5-6K/sec, not 10/100 Mbps.  Token Ring based systems work better under low-performance/low-bandwidth situations, because only one calc can send at a time.  Look at the MBus routines available for a good software only TI-calc networking protocol.  There's already a chat client out, but unless we get "TI-jacks" at every desk in every school, it won't really make much sense.  But I like it.  Very IRC-like, and can be used by over 200 people at once.
For a simple connection system, you want to make the three parts of each link port on every calculator the same point, electrically speaking.

For this, use a "T" or "L" based system.  Your physical layout isn't all that bad, but you may want to put in some sort of terminating circuitry (a resistor).  The pass-through approach is great.  But don't count on the "standard" link cable.  TI changed it.  I just saw a TI-86 being sold at Price/Costco with a new link cable design.  No more 90-degree offset, it's a straight cable now.
