  Re: mindstorms NXT and memory
 
(...) It depends on the application obviously...but thinking of consumer devices that cost around the same ballpark as the NXT and which are likely to be sold in similar quantities, we have PDA's, handheld games, MP3 players and digital cameras. * (...)

(...) It's also possible (likely?) that LEGO are using an already available ARM7 chip, such as (URL) or (URL) (18 years ago, 9-Jan-06, to lugnet.robotics)
 
  Re: mindstorms NXT and memory
 
(...) Just FYI, I programmed an ARM chip over 10 years ago (so it must have been a less powerful one than this). The assembly code was surprisingly clean, simple, and powerful. ARM is a great architecture. Something like BrickOS with a GNU C (...) (18 years ago, 9-Jan-06, to lugnet.robotics)
 
  Re: mindstorms NXT and memory
 
(...) Well, there's a significant cost above and beyond the electronics here. The NXT *might* be comparable to a PDA, but tossing in 500+ precision-molded little plastic parts probably drives the cost up considerably (heck, just from buying sets I (...)

  Re: mindstorms NXT and memory
 
(...) I keep hearing this (and reading in the official press releases) but having recently shopped for a cell phone, I can tell you that everyone available here (Ontario) that I can find has the bluetooth crippled to it will ONLY talk to bluetooth (...)

  Re: mindstorms NXT and memory
 
(...) I agree. When the RCX was found to have limitations in the enthusiast community I can't say I blamed LEGO that much. With the RCX they didn't know they were going to have a market with hobbyists anywhere near that size. Now we have the NXT. (...) (18 years ago, 9-Jan-06, to lugnet.robotics)
 
  Re: mindstorms NXT and memory
 
(...) Ouch, that's bad. Here in Sweden I can confirm that bluetooth phones with other features are around - for instance, my own phone can sync, and others can be used to remote control toys. Apart from the Ericsson car, I found TV output and (...) (18 years ago, 9-Jan-06, to lugnet.robotics)
 
  Re: mindstorms NXT and memory
 
(...) Well, *any* machine is harder to program at machine code level. If you mean assembly, I diagree. I spent the first 18 years of my career on IBM mainframes, and the last 5 on SPARC machines. They each have their advantages and disadvantage from (...) (18 years ago, 9-Jan-06, to lugnet.robotics)
 
  Re: mindstorms NXT and memory
 
(...) One (Verizon) of the 2 top carrier's in the US tried to cripple the bluetooth in at least one model, and it created a large PR storm. I"m not sure whether they changed their position on that model or on future models but I havne't heard as (...) (18 years ago, 9-Jan-06, to lugnet.robotics)
 
  Re: mindstorms NXT and memory
 
(...) That could have something to do with the fact that the x86 architecture is extremely low on registers, pretty much all of which have special functions (CX for counting, BX for addressing, AX:DX for multiplications, SI+DI for memory copying). (...) (18 years ago, 9-Jan-06, to lugnet.robotics)
 
  Re: mindstorms NXT and memory
 
(...) off the shelf makes a lot of sense. Think of the development costs of using ARM IP on a custom chip. Suddenly LEGO would become a hardware development group, and the costs would be really high. Even if they used PLAs, they would still have a (...) (18 years ago, 9-Jan-06, to lugnet.robotics)
 
  Re: mindstorms NXT and memory
 
Another possibility for the grinder bunch is seeing if the onboard flash chip can be SMT desoldered and replaced with a larger capacity model with the same pinout. I'm assuming there will be various third-party OSes to run on NXT pretty quickly, so (...) (18 years ago, 9-Jan-06, to lugnet.robotics)
 
  Re: mindstorms NXT and memory
 
(...) Kevin, does that have to be true though? I'm wondering if a better strategy would have been to sell the NXT Core kit at a slight loss but try to make it up on expansion sets? (sort of like the game console market) Give the NXT more (...) (18 years ago, 9-Jan-06, to lugnet.robotics)
 
  Re: mindstorms NXT and memory
 
(...) I doubt it -- for game consoles, the computer is useless without the 'expansion sets'. For Mindstorms, most consumers will be happy with the basic product; expansion sets are add-ons, not required purchases. I don't see a way to transform (...) (18 years ago, 9-Jan-06, to lugnet.robotics)
 
  Re: mindstorms NXT and memory
 
(...) That's a really good point. I suspect LEGO feels that the basic, core set should cover all the bases to make access to Mindstorms/NXT easier for kids and their parents. Though there still maybe avenues in the future to offer a more advanced (...) (18 years ago, 9-Jan-06, to lugnet.robotics)

Well, not NIL - but less likely than perhaps you might like. However, it's gonna be (...) (18 years ago, 9-Jan-06, to lugnet.robotics)

  Re: mindstorms NXT and memory
 
(...) You forget LEGO already did that with the Scout in the Robotics Discovery Set. But perhaps it was too limited for people to want to buy it. If the NXT has a memory expansion slot inside it that would satisfy quite a few people I think. (18 years ago, 10-Jan-06, to lugnet.robotics, FTX)

I think about 15 games support it currently. Anyway, my GBA is one thing I'll (...) (18 years ago, 10-Jan-06, to lugnet.robotics)
