The following versions of Kepler X hardware currently exist

  • The first board I made and exhibited at MI68 in October 2022, where I gave away the raw board and some of the kits to some people
  • The board has numerous bugs and must be patched. For the patched boards, I have assigned the following versions for your convenience

    • v1.0.1 The patched board that has been modified to work the function I supposed to at the time of board design
    • v1.1.0 with additional modifications to connect mt32-pi
    • v1.2.0 with additional modifications to use kmmcscsi function to connect MMC cards.
  • The details of the patch are described in "KeplerX-v1.0.0-Assembry-Manual"
• Machine No. 2 (v2.0.x)
  • This is a newly created board with the features of v1.2.0
  • The main differences between this board and the No.1 board are as follows
    • mt32-pi support
