Apple II

Hi everyone, I have this floppy disk drive card witha a shugart port.

I can't find any information about the manufacturer.

Does anyone know of any documents with information about this board? 

what are jumpers switch for?

What I mean is the brown connector located on the keyswitch PCB of the twin PCB keyboard assembly. The other PCB is the keyboard encoder which has a corresponding 25 pin long pin strip and this one plugs into the wanted connector.

I dare a guess it might be a MOLEX connector but this is suspect wetware memory recall from 45+ years ago when these connectors were popular (human brains = wetware do not have ECC ;-)

Anyone able to identify this connector and tell me manufacturer, part number, and where it's still in stock ?????

I noticed that the Apple III Fortran disk has a file named READ.ME.FIRST that is an ASCII file. I tried to view it by loading it into the Apple III Pascal Editor, but when I tried to use the Apple III Pascal Filer Get command to load the read.me file I get an message stating 'No File loaded'. How does one view an ASCII file in Apple III SOS?

Hi. I recently acquired from local aftermarket a Quadlink board. It uses unusual DISK II drive controller, which is very picky in relation to diferent 360K PC drives. Roughly 40% of my otherwise perfectly working PC drives are reading well diskettes writteln by  standard Apple2 computers. The rest fail when used to read Apple2 diskettes. The problem occurs with decent  error rate on external tracks usually from 0 to 9. The more the head moves to inner tracks the more the "non working with qudlink" PC drives read flawlessly inner tracks.
