Hydra location of SD?

Guys,

I'm working on a revision of BASIC as defined by Andre in "Potatohead's Plan" thread.

I'm curious if the typical Hydra owner is using an SD card yet, and where this card is being
hooked up? P16-P19?

Thanks
OBC

    I don't have the manual in front of me of where·I mapped the IO lines on the expansion port, but I would just make it programmable, so it can use any of the IO..7 lines.

    I am laying out the SD card right now...

    I'm using an SD card on what appear to be the most common pins:

    DO- 16
    Clk- 17
    DI- 18
    CS- 19

    Yes, that's good, that's what I am planning to use the first 4 pins of the interface IO0-3.

    16,17,18,19 work perfectly for the SpinStudio setup as well, since the SD card
    simply plugs into the head intended for VGA. (Could we be seeing some standards arise? Nah... [noparse]:)[/noparse]

    I have a working FemtoBASIC that does what Andre specified in message two of this thread..

    (Potatohead's plan thread) But I sacrificed the EEPROM routines for more memory space.
    I figured if there was an SD card in the works, it would see less use.

    My code isn't the same, but the functionality is there...
    I have a simple drawing program working with the NES controller. (Among other things)

    I like the idea of an approachable language that a beginner can get started with.
    (One that really does something...)
