Hi guys; I've got a Teac FD-235HF 5291 from a coworker, since I was mentioning that I was looking for old Teac drives to adapt one on the Amiga.
Do you know if there is a walkthrough, about how to adapt this floppy to work on the amiga? From what I understand, some floppy works out of the box, while others require some sort of mod, to be able to function with the amiga (I need just a 880K floppy, no HD).
This floppy drive has only the DS0-DS1 jumper, so I am not sure if that is enough...I am not that hardware savvy about drives, and the various posts that I found, where quite technical :(
Thanks!

Yes there is a walk thru on the web about switching the disk change line, just Google "Amiga Teac FD-235"
-
If there is no jumper for disk change you will have to do some soldering or get a conversion floppy cable.

Thanks for the reply; tried to look for teac mods for amiga, but there is a model that pops up all the time (the one with the many jumpers in the back), while my model has only the jumper for DS0-DS1, so I can't follow the instructions.
I heard that you can swap wires to adapt them, but I can't find a specific guide that tells me which ones are the pin to swap.
I was not aware that there were so many variant of the same drive model (235HF); but the drive is free so can't complain :)
Checked aminet, and found a LHA file (floppyinterfac.lha), but the content is not visible on my mac, neither the doc, pcx or iff file open with any of the apps that I tried, so I have no clue what kind of info it contains.

Thanks, altho I have questions:
- the picture show the external connector...is the internal connector the same pin?
- the floppy is a sony...same as teac?
- I have no electronic background, other than the basic one; and this diagram looks like an adapter right? So I can't just swap wires on the flat cable...I need to actually hook up components?
Thanks!

Found something maybe.... is this true?
1- swap 2 and 34
2- move 10 to 14 and 11 to 13
3- move 12 to 16 and 13 to 15
4- move 14 to 12 an 15 to 11
5- move 16 to 10

this list may help. there are some illustrations. match your board layout to one of the teac's here and the changes will likely work.

also excellent thread on EAb here:
http://eab.abime.net/showthread.php?t=30944&highlight=teac+fd-235hf
if the drive needs mods, its easier to solder them on the drive board than mod a cable, this way you can always use a regular cable.

Thanks Mechi, but the first link was of no help...found that already and they only have few models of the 235HF.....the 5291 seems to not be there, nor referenced anywhere.
Read the second link thread, and sadly even there, I see mixed info about how to make a drive work....the amount of info fragmentation is quite scary; since some says that is enough change the wire, others says that without the RDY signal you can't use ndos disks; others says that you must avoid the cable fix since it damage the drive... I am more confused than before honestly :(
BTW I've plugged in today, and it turns on but it won't click nor read when I put a disk in...at least this is enough to say that the drive at least is not broken.
IF only Amigakit would not ask 30 dollars to ship oversea; I would just buy one from them >_<

I do not know if this will help but it does include the jumpers for ds0 & ds1.

I have done a ton of these in the past,and even if you cant find the exact floppy #(teac made a ton of different ones,with simular boards),match the board with the same chips, the mod will then usually work. diskchange will work on them. unfortunately i couldn't find the exact links with the initial quick search but im pretty sure its out there.
edit: think this is it.. its in german but has pix...

If you just cant get this done, let me know, and i will dig a pc floppy out and mod it and ship it to you pretty cheap.. it may not be pretty but it will work(assuming you are in the usa, it doesn't show on your profile).

Thanks Mechy; indeed I see a ton of models; and there is one that looks remotely like mine (has 1 jumper like mine; can't tell much from the photos since they don't show the PCB)
I am in the USA (CA); if it has a mask which is in good shape (I gotta paint it white anyway so if it is dirty I don't care), that may work...I can send you the one that I have, as partial contribute...I have no use for it since I don't have a PC.
I just need one to work as internal drive for my case conversion :)
Thanks for the offer! sending you a PM
