Who needs a new car when you could buy a floppy drive?

D.Finni:
I'd like to try connecting a Twiggy to the IWM in a Macintosh because I think the IWM can control them. What I don't know is to what extent, if any, the Twiggy drives in the Macintosh differed from Twiggy in the Lisa. Anyone here have any insight?

For a brief time I had a Macintosh Twiggy drive on my bench for repair...

IIRC:

* The Mac motherboard was the same as a 128K Mac (so yes, your IWM will work)

* The Digital Board for the Mac variant of the Twiggy drive is different from the Lisa variant. I think I have a picture... :-\

* The only difference in behaviour compared to the Sony seemed the polarity of one (or more?) of the sense signals was inverted, but I may be imagining it.
If I can find notes/pics I'll upload to the file section (... and I did)

That's what I was getting at with my question. Also I see that the Lisa Twiggy had a 26-pin connector whereas the Mac ended up with a 20-pin connector.
