The Sinclair QL Forum

I have a Samsung QL with miracle trump card 1 768 and a Gotek drive. The system worked fine but now while any proccecing is executing the mdv1 is spinning.
The ql load and save on Gotek as flp1_ but the mdv1 is spinning.

Does the Mdv spins when the TrumpCard is unplugged too?

Hi,

Clean the pins of 8302, 8049, check bent pins on expansion port.

You could check the Microdrive data cable is located in the socket on the board.

I had a similar problem with a microdrive. Have you tried swapping mdv1 and mdv2 to see if it's a drive fault, or a motherboard fault.

In my case it was the actual microdrive unit that was at fault. I'm pretty sure the ULA is the problem on mine. Something to do with the drive select and enable signals from the ZX8302 not passing through.

I did not replace it as they are hard to get hold of, and I ended up using the drive unit as spares to fix another microdrive unit that had a faulty tape head.

Thanks for your advice's. I ll check it next week.
The next thought is to remove mdv1 and use the gotek as boot drive flp1_
