Someone gave me a SupraExpress 33.6 modem for Macintosh. Only the modem, no power brick, manuals or software. Does anyone have any information about this type of modem? A manual, product sheet, technical specs, anything I can use to identify how to power it?

Nevermind, I finally figured out that the modem is powered by the ADB port. Duh!

You mean Serial, of course...

No, it's ADB. The modem has two plugs. One is for the serial port. It took me a while to figure out that the second one is actually a dual male/female ADB connector. Male for the computer ADB port, female for plugging in the keyboard.

I have a radio that connects to the Mac (FM Radio, from Lacie) and it also draws its power from the adb port.

Yup ... It's ADB port powered.  I have a SupraExpress 288 powered the same waw.  Also a Wacom tablet powered that way.  When they are all installed on the same machine, it makes for a really strange looking ADB port.

Off topic ....  Anywhere, has anyone run into an ADB to USB adapter for keyboard and mouse.  I would think that it would be possible to do something such as you see on PC's. ADB is probably too slow for anything else but with a power source it seems to have the basics already for this type of application.

Why not just put a USB card in your Mac?  I'm assuming that you're using a Mac with PCI slots.

To answer your question, there is no ADB to USB adapter that I'm aware of.

There is an ADB to USB converter, but I don't know how well it works. It's called the iMate, and I think it is made by Griffin.

The Griffin iMate is a USB to ADB converter. They work with Mac OS 9 and later. The iMate is somewhat popular because it allows you to use older Apple ADB input devices (within limits) with new Macs.

I put a USB card in my one of my old world powermacs before.   It worked fine.  All he's wanting to use is mice and/or keyboards.  ie. typical devices that you would plug into an ADB port.

I guess you're right.   Apple's USB software says that it requires Mac OS 8.5 or higher.   And I don't have an old world PowerMac that will run 7.6 so that I can try it.

Yes, when they're running Mac OS 8 and 9.

USB, unlike FireWire, is entirely software controlled.  I would be amazed if even mice worked with System 7.

Back from Easter with my Kids.

The machine I am thinking of specifically is a 7100 - Nubus.

At some point in time, I will either have a keyboard or a mouse or both die.  simple replacement would be good.

The iMate from what I read allows old peripherals to link to a new mac.  I am looking to go the other way around - new peripherals to an old Mac.  

It is not a critical itme as I think one can get both keyboards and mice if one looks around.  Just looking for options.
