/// PARALLEL PORT -> I2C BUS CONVERTER - DESIGNED BY KOCHISE /////////////////

Hi world, here is the coolest //2I2C (Parallel 2 I2C) card I designed.

--- INFORMATIONS -------------------------------------------------------------

Picture files       : PARAI2CT.[GIF/IMG] -> Top layer of the card
                      PARAI2CU.[GIF/IMG] -> Under layer of the card

Pictures resolution : 600 dpi (if printed in 600 dpi,
                               you'll get the exact size)
Picture mirroring   : Valid (when printed, put the ink face against the
                             copper to avoid UV diffraction)

Bill of Material    : 1 * DB 25 male connector
                      1 * capacitor 10uF
                      2 * resistor 1k OHM
                      4 * resistor 10k OHM
                      1 * IC 74xx05
                      2 * connector pins for power
                      1 * 5*2 male connector for I2C bus report

--- COMMENTS -----------------------------------------------------------------

PS One : One of the revision I made doesn't work at all. I don't remember which
         one, and it might be this one !!!

PS2 : I don't think I coded the I2CBUS.CPP using this card. There is a large
      variety of I2C cards, depending on the bit configuration on the parallel
      data port.

Dreamcast : Well, you can also use ONLY the Under layer, since there is no
            circuitry on the Top layer !
