BeeCard Reader/Writer project

Beecard reader

A work in progress, so far I’ve managed to build a BeeCard reader (writing doesn’t work) around an Arduino Mega (ATMega) and a BeeCard purchased from someone who sells old Atari parts (Atari Portfolio.)

I had tried to use the Portfolio BeeCard (32K SRAM) in my Korg Wavestation however it doesn’t provide the battery voltage on a certain pin therefor the keyboard always rejects it as a low battery.

My attempts to write data to the writable BeeCards I have has yet to work. I’m not sure where I’m going wrong, I’ve tinkered with the various control lines and can’t seem to get a write to happen.

My read ability might of been an accident? But it’s what I needed. A sloppy python script dumps the card to a file. Not sure if I will revisit writing the writable cards.

  1. Hi Ethan,

    I read this article with great interest as I am looking
    for a way to read (and ideally write too..) Atari Portfolio Beecards on a modern PC, so I’d really like to know more about your Arduino-based shield and sketch.

    Would you be willing to share the schematics, parts, and Arduino code ?

    Also, on one of the images there is a printout of one of your articles about “Korg Wawestation Multicard”. Zooming in on the picture I was able to see the URL however it seems it is restricted access:

    Would you also be Ok to share the info shown on this page?

    Looking forward to your reply,

    Kind regards,
