I like the JCX concept. When/If I had $500 to spend on it, I would.
I think of JCX as a RCX 4.0 or even 5.0
Before jumping to a 4.0 or a 5.0, I would like to have/see a RCX 3.0
So... if in TLC shoes I would do this:
RCX 3.0 = RCX 2.5 - battery compartment + Power Input port(1) + Memory(2) +
High Speed Data Comms Ports(3) + new firmware to support
"daisychain-network" commands
(1) accepting external batt compartment, rechargeable "pack" or mains
adapter like RCX 1.0
(2) double ? triple ?
(3) 1 input + 1 output wired data port. Be it mini-usb, be it ethernet, be
it LEGO proprietary 2wire data wires, whatever... if a standard 2x2 2wire is
used, then one could tell kids: use the BLACK wires for power ports, YELLOW
wires for sensor ports and RED/BLUE wires for RED(in)/BLUE(out) *comm*
ports.
The IR could be built-in like all RCX *or* could be the 1st of the
comm-modules connected to this daisy-chainable comm-port. Then, more
comm-modules could be issued, like cybermaster-compatible RF-module, or
anything more standard, like hard-wired RS-232, USB, proper IrDA, Bluetooth,
whatever comm-modules.
Yes, that's what I think we lack on a RCX 3.0. We have power output ports,
sensor input ports, but no proper way to expand it. We lack comms *ports* !
...there's no simple way to daisychain various RCX with strong and fast
comms. The IR's ok for slow, simple, in-sight comms, nothing more.
bottom line: 1st priority, we need a LEGO data bus.
mc.
PS: I know, I know all these are beaten to death ideas here :)

| (...) For those for whom one RCX does the job, there's no reason to switch. The original context of this thread was people frustrated by lack of more processing power and wanting a lot more inputs and outputs. What about those who are using three - (...)
