Hello Friends! I just "repared" a B-Drive sold by "iGTH&H inkoopbureau" in 1996, Model: SONY MP-F17W-12. This drive didn�t work with a Sony HB-D700, but had been "tested=OK / MSX only". But what I saw when I opened the case declared everything to me: Pin 34 of the connector normaly has DiscChange signal in this Drive. So a Diode to DriveSelect had been mounted to simulate ReadySignal (It�s OK). BUT THE DISKCHANGE SIGNAL WAS NOT REMOVED!!!! So the two signals disturbed each other. Terrible mistake! And those drives were sold in Tilburg e.g.! My "Repair": I removed that Diode. And near Pin 34 there are some soldered jumpers (SL2). I recognized that the jumper places A and B are connected to Pin 34 and only jumper B was in place. This jumper connected Pin 34 to DiscChange. I removed it and sold it to place A. Now a true ReadySignal is connected to Pin 34 and the drive works well with the Sony. Is it possible that there are more drives that doesn�t work???? Bye Martin **** MSX Mailinglist.
