My 1040STe has some modifications;
Quadtos (1.06-.1.62-2.06-SuperTOS)
And
boot floopy selector (by wiring 2 of yamaha chip pins)
I did that because wanted to boot from my gotek (which has HxC fw)
now i don't need to boot from gotek anymore.
All i want is copy from st to real disk.
but i tried every combination but no way my ste see the contents of a and b drive same time. so i cannot copy disks. What do i do wrong?
Whatever i do, I cannot access both drives. Only one works.
My friend made this mod.
Let's see if my mod is faulty.
Pin 19 Chip --> Red --> SW 3
Pin 20 Chip --> Green --> SW 6
Pin 19 MB --> White --> SW 2
Pin 20 MB --> White --> SW 5
Switch numbering (Solder Side)
1-2-3
4-5-6
There is also 2 blue wires soldered;
Blue Wire 1 --> SW 1 to SW 6
Blue Wire 2 --> SW 4 to SW 3
Conclusion;
SW Left (External Boot)
1(which connected to 6) to 2 --> 19 MB to 20 Chip
4(Which connected to 3) to 5 --> 20 MB to 19 Chip
SW Right (Internal Boot)
2-3 --> 19 MB to 19 Chip
5-6 --> 20 MB to 20 Chip
