Floppy controller chip?

[vavido]

Hi Emulator guys!

I have a really nice emulator II+ HD, with only problem, it will not boot. I have installed the Hxc drive but the result is the same with the "insert diskette" massage. (First time I installed the Hxc I got the "file format error" message instead , but after updating the firmware to latest version 1.8.xxx the "insert diskette" massage is the only thing I have.

I have checked the cable and power and everything seems fine, so now I suspect that the floppy controller chip could be corrupt.

Anyone have an idea where to find this chip on the main board? 

Kind Regards

Found out via this excellent forum that the Z80A SIO/2 chip could be corrupt. Ordered it from UK, and now the floppy disk is working, and my emulator II+ boots up !

My sampler is originally an HD version, but the ROM chip and the scanner has been changed to support  the non-HD version. Extremly happy now! :-)

The Lotharek disk emulator is not working yet, but I guess it must be the cable or the jumpers.

There's also a chip, 24 pin, WD1711, if I remember well (that's 30 years ago, mate !) Take it off and put it back
