I have a little problem with my A1-WSX.
A long time ago I changed it's original FDD by a PC one. The problem is that the FDD waits for me to put a disk if i want the computer to go on to the basic mode. It happens the same as with the amiga computers. I read it could be solved by keeping pressed or solding the conections of the "disk inside" sensor. I will try this stuff but i'm not sure it will work properly or if it will make the computer act atrange when there's no disk at all, for instance.

If anyone has had the same problem it would be good to know about it.

I had the same with my Turbo-R. I think the hardware design of the Turbo-R and de WSX should'nt differ too much, so you may try the following... (Naturally this may lead to a smoking heap of MSX, ofcourse...)

Pin 6 of the Turbo-R drive connector holds the ready signal. Ground this when a disk is inserted. Most drives have a suitable sensor. Make sure you check it goes to ground, not 5V when a disk is inserted. If so, connect the ready pin to this sensor. My drive had an optical sensor which went high on disk insert, so I had to place a small switch instead. It has worked fine for some time now. Check to see if pin 6 also holds the ready signal on your WSX. My guess is that it does...

I really don't know if the WSX also has the 'disk changed' function the Turbo-R has. If it does it is most likely on pin 24 as well. If the WSX has it too, try either grounding it for a quick'n'dirty fix or ground it whenever there is NO disk inserted. If you need to place a switch like I did, make sure it has a dual throw (?) so you can connect the 'disk changed' pin to the opposite side of the switch.

I think you're not supposed to leave the pins 'open' at any time and are supposed to hook them up to a resistor and 5V+ or something, but I really don't know the exact science behind it. I just left them hanging anyways; not how it's supposed to be, but hey... Anyways, that's how I solved the problem. Seemed to have worked just fine. The drive doesn't work as neatly as the real Turbo-R drive did, but it does the trick and all software seems to work okay. Anyways, good luck..
