    Default How do Lisas connect to a Widget drive?

    More mass storage research. I'm looking at how the Widget drive worked and how it connected to the Lisa.
    The major problem I have come across so far is I have a round peg, square hole situation where the power cable and the power connector on the widget are different and for both the widget and the 400K floppy drive there appears to only be a single ribbon cable. My assumption is that there's a board that goes in between the Widget requires more hardware than just the logic on the drive but I have never seen one. Most people who own a Widget do not remove them from their Lisa or the camera angles are too poor to see what's going on behind the drive. The best I can find are photos of the drive itself.

    One thing worth noting is that my Lisa was one of the original units that got upgraded and probably originally used a ProFile.

    There is a Widget drive on ebay with photos: http://www.ebay.com/itm/261107352729
    The connectors on the X-Profile might give some hints too: http://www.ebay.com/itm/200752885647

    The Lisa 2/5 used with a Profile drive and the Lisa 2/10 (Mac XL) for use with the widget look much the same but actually there are differences. Sounds like you have the Lisa designed for the Profile. There will be no internal connector on that machine for a widget. I'm in a rush right now so can't dig out the info but if you google around you'll find websites that explain these differences.

    Bummer. So no instant option.
    I do notice that the Widget needs a 25 pin ribbon cable. What's the chances that the Widget can be plugged into the parallel port like a Profile?

    Not sure. The widget does use an internal parallel connector, but it's more than just the connector that's different between the two models. The I/O card is different is well. Some of these differences are explained here.

    Mind you this ebay item would suggest perhaps you could connect a widget to the external parallel port. I mean, if you can go one way, maybe you can go the other?

    Not a Lisa user or owner myself, but have researched them a lot, in hopes I will someday find one at the right price. Anyways, in my researching I stumbled across this site, they sell a Widget/Profile drive emulator/replacement it uses CF cards, much like the XT-IDE project here does for PCs. Seeing that they have built a device that emulates the Widget/Profile, I would assume they would have all kinds of information on how the connection works, however since their board seems commercial in nature, who knows if they would be willing to share that information, but worth a shot.

    EDIT: I just found this site doing a quick google search, it has a lot of information on the Profile specifically, and its interface, doesn't dig much into Widget though, looks like a much more open project for emulating the Profile drive.
