- A couple of Questions for anybody who's put
- a 720 K floppy on their 3B1/7300/unixpc:
-
- I'm attempting to attach a 720K floppy drive
- to one of the 3B1's I've got here. This has been
- done before, and documented in comp.sys.3b1.
-
- Now, I'm wondering, what kind of cable do I buy?
- The cable I've got goes from two rows of pins to
- an edge connector, but the connector on my 720K
- floppy drive is also two rows of pins, like the
- connector on the motherboard.
-
- I'm assuming that it's a pretty standard part,
- but I don't know if there are any special cable
- twists needed, or what.
-
- Meanwhile, there didn't seem to be anything in
- the literature sheet I got from Panasonic about
- how to make the floppy drive operate only in 720K mode,
- is there anything special I should do, and if so,
- what am I looking for on the options sheet?
-
- Are there particular options I'm trying to set besides that?
- If anybody is REALLY knowledgable, this is a Panasonic JU-257,
- has an "AT&T" label on it too. The option sheet lists options for
- Display LED light up
- DISK CHANGE signal reset
- I/F connector pin2 option
- I/F connector pin34 option
- although it's not quite clear from the sheet exactly
- how one would go about changing these -- no jumper positions
- cooresponding to most of the names are shown.
- ( it shows DC, R61, R66, R67, R68, R69, R70, R76, R77, R110, and RY.
- DC and RY are particular jumper positions shown previously,
- what are the rest? )
-
- Thanks 400K's worth (in advance),
