Hi all,
I have an Advantest network analyser that uses a Teac FD-235GF 3156-U
floppy
drive. Teac cannot/willnot provide any information on the drive or a
suitable teac replacement. They tell me it's a proprietary drive and
to contact Advantest. Advantest won't help either, the analyser is
past service support life.

Anyone have a collection of NOS or even used FD-235GF 3156-U drives I
can buy ( want around 3-5)

Or - anyone have any info on the teac 235-gf apart from the teac.jp
website glossy and any knowledge of a suitable replacement?

If I can determine what the jumper settings mean perhaps I can find
another drive that would suit. Anyone have a copy of the service
manual for the drive that identifies the jumper settings?

The jumper configuration for the drive as installed in the 3762ah is
per the following list.
A1-B1,B4-C4,B3-C3,D4-E4, F1-G1
D1-D2, E2-E3, G3-G4

Any help appreciated

Thanks
Greg

That could just be a standard PC floppy drive. Teac FD-235's are/used to
be used in IBM compatible PC's. I'm sure I have some kicking around.
I'll have a look on Monday when I get into work.

Hi Baron,
the PC drives are FD-235 HF not GF as far as I've been able to identify
and
the jumper set is different.

For the most part I reckon all I need is to know the jumper matrix
settings,
from there I should be able to sort out modifying any current drive to
suit.

However, if you do find some GF drives I would be most interested.

Thanks for the help
Greg

Hi Larry,
thanks for the links - unfortunately not much use I'm afraid. I hadn't seen
that pdf on the teac site but as it was about HG to HF differences no
mention of the GF drive.

I'm particularly looking for the GF drive not the HF drive. The jumper pad
on this drive allows for all sorts of non standard pinout configurations
such as density select on pin 6 rather than 2 etc. The problem is some of
these interfaces have changed over time, for example the density select can
be either an input or an output or both depending on the drive and the
controller and without the jumper data I'm not sure how the drive is
actually configured to operate.

The controller on the drive is a T4A34F, again no luck in finding any info
on this chip to allow me to identify what pin goes to what jumper. If anyone
has a datasheet on that teac IC that would also be of some use.

Thanks
Greg
