  Re: How much memory finally?
 
Thank for the answer, Dave, this is the kind of info I'm looking for. BUT! I don't think it is correct: 0x8000 is 32k: the firmware would start at the end of memory!?! 0xbfff is 48k: unless the 16k of the rom are counted of course... Then this mean (...)

  Re: How much memory finally?
 
(...) I believe it has a 16K ROM and 32K SRAM. Within the 32K, 16K is occupied by the 'firmware' downloaded to the RCX. About 6K is reserved for bytecode program space and the datalog. Presumably the rest is working memory for the firmware (stack, (...) (26 years ago, 10-Feb-00, to lugnet.robotics.rcx)
 
  Re: How much memory finally?
 
(...) If I remember correctly the RCX has a 16kROM for the basic routines. It has 32k RAM for firmware and programs. The scout has 32K ROM and only 1K RAM (400bytes for your program) Dean (26 years ago, 9-Feb-00, to lugnet.robotics.rcx)

(...) The 'official' adapter, is 10VAC, 0.7A. I have seen one person who blew the rectification bridge, and he simply replaced this himself ((it was an old unit).

  How much memory finally?
 
I'm trying to figure out how much memory the RCX has. Many sources claims that it has - 16k rom - 16k ram for the firmware - 6k reserved for our own programs Does this mean the RCX has 22k of RAM memory? What an odd number... Also, when I perform (...)

  Re: Radio Shack CDS cells in parallel
 
(...) ----- True, but the RS CDS cells are cheap and using them in parallel or series also changes the response range, since all the resistances change with light levels. This would be most dramatic in the series connected case at the low resistance (...) (26 years ago, 9-Feb-00, to lugnet.robotics.rcx)
 
  Re: Radio Shack CDS cells in parallel
 
(...) I built a sensor out of one of those and it works fine, so yours is probably defective. I superglued mine to the top of a 2x2 brick with the studs removed. You can see my high tech design at (URL)I tried this idea and it worked. You can put (...) (26 years ago, 8-Feb-00, to lugnet.robotics.rcx)
 
  Re: rcx 1.0 and an ac adaptor
 
(...) According to Knudsen's book, AC or DC in either polarity is fine (which is great!). That's the only place I've seen the input characteristics mentioned, is there an "official" spec anywhere? One thing you might want to be careful of: I read (...) (26 years ago, 8-Feb-00, to lugnet.robotics.rcx)
