Hello,

I have just picked an old Apple II EUROPLUS. Inside, I have discovered the usual cards except one which I don't recognize. Does someone know which card it is?

Thank you

Re: Help to identify a card

Hello olivierb,
first welxome to the platform.
Answer to the given question:
The card is one of the versions of the FDC4.
The original card was made and distributed by Ehring.
It´s a floppy controller card that offers the chance to connect
either 2 Apple II DISK II drives or
2 drives with shugart bus ( 34 pin floppy cable ).
At this card the logo from Ehring is missing and the layout changed a slight bit
so it´s a clone.
Information about the original Ehring FDC4 card is availiable at my site at:
http://www.appleii-box.de/003_appleboxdownload.htm
at the lower part of the page and at:

Hello SpeedyG,

So I can use that CTRL with any low density 5.25 floppy drives? Does it also support 3.5 drive?

Thanks for the answer.

Re: Help to identify a card

Hello olivierb,

in general that controller also can use lowdensity 5,25 drives
with eiter 40 or 80 tracks and single-sided or doublesided.

But in fact that controller does not work very well with "normal" drives.
In former days in Germany that controller was used with the TEAC 55-F
drives and that drive was slightly modified for better cooperation with
that controller.

I have the description of that kind of modification somewhere within the dungeons
of my archive. But at the moment i haven´t discovered it again and therfor that
description is still missing in my site.

If i have luck that document will be found within this summer and added to the site.
In that case i will update my reply here with a link to that page.

sincerely
speedyG
