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

I've made a note about that difference ! I have some weird HP kit
kicking about with 3.5" floppies in them ! Without looking I'm sure
that they are Teac drives. I'll find out tomorrow.

Hi Greg,

I'm very sorry about that ! I felt sure that I could help. :-(

Hi Baron,
no problems. Thanks for looking though.
I've had some success using a standard pc drive. Had to use DS0 rather than
DS1 (expected) and needed to ensure the drive was using disk change on pin
34. The only thing that is still a little peculiar is the density select and
whether it's an input/output or both. Using a standard PC drive I need to
use a HD disk but cover over the HD hole and that seems to work reliably. On
the original drive I would use HD without covering up the hole. The only
issues I end up with is that the drive light is always 1/2 on when not in
use.

I'll keep looking for FD-235GF data and playing around. i'ts almost sorted
now

Thanks

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

FWIW, this document refers to FD55-GFR 5.25" drives:
http://www.teac.com/DSPD/pdf/5fd0050a.pdf

There is an LG strap and an I strap that define how the drive behaves
in lo-den and hi-den modes.

You might want to pose this question to the floppy hardware gurus at
"Individual Computers."

They make a product called the "Catweasel" which reads all floppy formats
known to man. as such, they proabably have some experience with drives.

Or Tim Mann is also a floppy guru.
