    Well, I found another problem with my OEM kit. It seems that I order the wrong EEPROM from mouser. When I looked up the part today its telling me its a 16K EEPROM ( link ). So I guess the BASIC Stamp 2 Interpreter can not recognize the 16k EEPROM and that is why it never shows up in the stamp editor. So it looks like I am ordering some 4K EEPROM from parallax some time this week.

    That would do it.· Glad you got it figured out.· Let us know the results after you get your new chips.

    Chris-

    I don't know if it was posted here or not but is it possible to have any size EEPROM connected to a BASIC Stamp 2 Interpreter? I am going to say no from what I know but I could be wrong. What about connecting it to a basic stamp module? Thanks.

    Matt,

    ·· No, the interpreter only understands 2K addressing.· That originally was a limitation of the architecture of the chip used in the Interpreter, however more recent Stamp Modules allow you to switch in/out extra 2K banks, but the interpreter will still require the approriate size chip that it's designed to support.

    Do you have any more information on this 2k addressing or know where I can look? Also what do you mean about extra 2k banks? Thanks.

    All the other BASIC Stamps have 8 or more 2K slots of memory available on them.· This memory cannot be accessed directly so that you can have a larger program, but rather it is broken up into these 8 slots which you can chain programs from or access (read/write) data in them from the current slot.
