MK I (SMS Cartdrige Reader)
Post Posted: Tue Jun 29, 1999 11:54 pm
I'm trying to make a modified version of MK I (SMS Cartdrige Reader).

The problem with MK I is that it requires a 8255 Based 24 line digital I/O card
and I think this card isn't on sale anymore.

I heard about another version of this cartdrige reader called MK II.
Anyone can confirm? Where can I get the schematic?

Well, if the MK II doesn't exist, We'll have to modify this schematic to use
the Parallel printer port instead of the 8255 Based 24 line digital I/O card.

Also, the program used to read the cartdriges with MK I, will probably not
work with the parallel port, so we need to build another program.

I know a little of how to code in C, but I have no idea how to read the
parallel port, neither the function of all the 25 pins.

All information is welcome :)

Sorry about the broken English, but "Me am Brazil" :P
