anyone have extra external floppy cable by chance?
« on: February 19, 2017, 11:00:15 am »
Hi! I'm out to buy a floppy for the x68k compact, but the external floppy drive doesn't come with required cable it seems. does anyone here by chance have an extra lying around?
or does someone know what kind of connector this is?

I found this old thread which can help me create a cable! yay :D
http://nfggames.com/forum2/index.php?topic=5099.5

as I understand it, the connector in the external FDD is 40 pin micro-d
I found this: http://www.ebay.com/itm/172196251201?_trksid=p2055119.m1438.l2649&ssPageName=STRK%3AMEBIDX%3AIT
and the internal FDDconnector is 34 pin micro-D or is 36 but last two pins are unused?!.. am I understanding this correctly?

anyone have the pinout for the external FDD? it doesn't seem to say in the thread.

The CompactXVI external FDD connector is a 40 pin D-Sub Micro-D :

http://www.mouser.it/Search/ProductDetail.aspx?R=10140-3000PEvirtualkey51750000virtualkey517-10140-3000PE

Some years ago I used it to assemble the adapter you can see in the attached picture, I needed it to interface my CompactXVI to external FDDs with 34 pin IDC connector.

Its pinout is essentially the same of the 37 pin Sub-D connector of other X68000 model, the pins from 38 to 40 are just tied to GND, pin 37 is unconnected.

I made a cable, but the motors inside the drives don't seem to start? I see the disk inside spinning... It becomes red, but I don't hear it actually start reading. Not sure if the cable is wrong or if the caps need replacements. The caps inside are blue/gray-ish ones, not sure if they were changed or not.

I used old IDE-cable.
I simply put 1-40 -> 1-40. Not sure if that was what I was supposed to do.

Double check connections, especially the soldering.Be sure also to tie all ground signals together.Don't forget that these sub D-Sub Micro-D connectors have special pin arrangement from solder side.

yeah I did a signal check that both sides have connection on the inner side. so I'm starting to think the floppy drives need recapping or something

great news... seems I was noob and had forgot to flip the switch on the backside of the external floppy.. now it magically works!

however as now the floppy drive works perfectly, I have noticed that my audio out from the x68000 red zone doesn't work. connecting a cable makes some noise, but there's really no audio coming out.
