floppy drive jumpers ??
kevin dermott
either in general or for specific models. this is not for any of my beloved
Ataris but for musical keyboards that use them
Thanks

I have built many a PC and fiddled inside a few ST's and NEVER seen
jumpers on a floppy drive... Hard Drives yes but a floppy...
or are these jumpers on the keyboard?

often tucked in near where the power supply goes, or tiny dip switches in
holes on the bottom circuit board usually to control RY DC and other
functions but they are not often labelled what does what

Well, you didn't look hard enough. All Atari drives have these jumpers, and
so did PC ones until a couple of years ago.
Depending on the model of drive, various things they allow changing are:
Drive ID 0 or 1
Media change detect
HD Detect
Most of these have either been replaced by solder pads on the drive PCB, or
just disappeared, as these settings are no longer needed on PCs. They are
needed to use a PC floppy on an ST though.
There will be no complete guide on jumper settings as all drives are
different. The only possible source is the drive manufacturer.

thanks this has been my problem I have been trying to get info on some Epson
and their site seems to be aimed at downloading printer drivers and sales
pitch for other stuff, I can't find a single reference to the floppy's the
produced probably in their millions

Some floppies have jumpers and others not. I think an Atari A drive
wants a drive 0 and the pc wants a drive 1. (I'm sure someone will
correct me if I'm wrong :-))

well if you fiddle inside an ST again and LOOK you will see some and if you
LOOK on the bottom of many Panasonic's you will see five switches some of
them with four positions !! SO THERE

All of them have some means of selecting drive 0 (a) or drive 1 (b). The
newer ones have zero-ohm jumpers that need to be unsoldered and moved
over. Look carefully, and with good light. There will be a "0" and a "1"
in small white print near the middle of the back edge of the bottom of the
drive. What needs to be done is obvious once you have found that.

look at Hallvards site Kev.
He and I and others did some research on this question, and the results
can be found in an ascii file there.

In old PC's ie. those with twin floppies jumpers weren't used. Rather than
have to set jumpers to select drive 0 or 1, the second drive cable had the
wires crossed over. Thus although each drive was set as drive 0 when drive
1 was selected the signal was presented at the drive 1's drive 0 pin &
drive 0's 1 pin as drive 1 so correctly selecting the drive. that may be
why you don't see jumpers on the drive. Drive 0 & 1 selection lines are
readily available on ST's, just make sure the the signal goes to the drive
0 contact on the edge connector.

Thanks for the Info and table for the floppy jumpers, it still hasn't solved
my problem which isn't exactly Atari, I have got this upgrade for a keyboard
that retrofits a hard drive interface via the floppy, the problem is that it
only works with the floppy it was sent with which concerns me in case I need
to ever replace it, the floppy is not modified in any way but has a lot of
dip switches on the circuit board, I have an almost identical one but with
no switches on, I am trying to find out what the sometimes eight pins are
for ,one drive I have even has two of the jumpers plugged into a small cable
going back to the power connector!!
All the best

ISTR a problem with some floppy drives not working on some Atari's due to a
pull up resistor on a select pin of some sort being of an incorect value
for that environment. Buffering of the signals or experimenting with the
resistor value cured this prob. You may have a similar scenario..

after further messing about with jumpers I have got the thingy to work with
a selection of old floppy drives, the only thing I can't get it to go with
is a brand new one that seem jumperless, there has been mention of
disconnecting a small resistor somewhere on the board but to be honest the
components look to small for a human to solder the only other thing I can
see are several solder pads that maybe could be joined to act as jumpers but
just which ones , no help from the Panasonic site like most it's all sell
and no info
