After some days of use some add i would like very much:
1) HD cliker with spinup spindown sound (a little speaker a transistor on free i/o sould be sufficient)
2) header to access led signal
I receive and installed XTA card on my ps/2 model 30 , and work like charm.
Only preparing SD card is not well explained (only a text file), and different hd emulation is not clear for me.
I have a ps/2 model 30 width failed HDD,
I will say "Shut up and thake my money!!" if this project will work for this PC and you will sell a board (and eventually publish 3D print adapter) to put in HDD slot of this PC.
HDD led emulating would be a plus.
