 | | 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 (...)

(...) ----- 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)

I have an rcx 1.0 and a universal adaptor (the kind with the different plug sizes and voltage settings). Two questions: (1) Do i have to worry about polarity?

| | Radio Shack CDS cells in parallel
|
|
When I first checked out the Radio Shack CDS cell five packs, the cells were all alike, about 1/4 inch and flat on two sides. But when I went back, I found some packs that had different cells. They had three of the usual small ones and a 1/2 inch (...) (26 years ago, 8-Feb-00, to lugnet.robotics.rcx)
