Resurrecting the USB to ADB adapter discussion

Hello all,

A while back (a couple of years?), I asked around about any project related to a USB to ADB adapter. I seem to remember someone suggesting that bbraun was attempting something like this, but I can't be certain.

In any case, I'd like to resurrect the discussion. Any thoughts on if/how/what steps are being made to develop a USB to ADB adapter. I don't mean the other way around (i.e. iMate ADB to USB). I'd like to be able to plug in a USB keyboard (for instance) into an ADB-based Mac. Why? Because AEKII keyboards are expensive and the non-mechanical keyboards (silicon/rubber actuators) are getting gummier and less responsive.

Any thoughts or developments in this area? Thanks!

Hmmm. So Steve is working on one. Wonder if he's made any progress since April. I shall...investigate.

I think there's a thread documenting another adapter development project in hacks over at the barracks.

Yeah, I think it's called ADB Busboy.

ADB Busboy: Adapter for USB peripherals over ADB rates positioning at the top of the pinned list in hacks. I've been meaning to read past the mission statement and working prototype announcement, but I've been much too busy. hmm

Ah very good. Seems this project is definitely well underway. Looking forward to supporting it with some of my cold hard cash (in digital form)!

Re: Resurrecting the USB to ADB adapter discussion

Wow, this is amazing!  I'm so sick and tired of most of my ADB keyboards and mice.  It's nice to finally have options, particularly where I need compact keyboards.  Doing away with the need for mechanical mice is going to be quite a joy!  If second-button and scroll can be translated properly, all the better.  I will absolutely buy more than one of these adapters once they go into production.

Re: Resurrecting the USB to ADB adapter discussion

I'm close to finished with the USB-to-ADB adapter that I started developing a year ago, but then procrastinated endlessly. I'm calling it Retro USB. Just got the first PCB prototype assembled today! Some of my blog posts about it are here: http://bigmessowires.com/category/retro-usb/

The current prototype also does ADB-to-USB, like the Griffin iMate.

I hope to have something ready for sale soon-ish. :-)

and... ta-dah! Retro USB is available for sale now. USB keyboards/mice on your classic Macintosh, or ADB keyboards/mice on a modern PC. http://bigmessowires.com/retro-usb/

Re: Resurrecting the USB to ADB adapter discussion

Cloning iMate at the same time was a stroke of genius, much impressed. Have you got support for modern joysticks or digitizing tablets worked out?

Any plans for treating USB storage as SCSI at some point? It'd be a bit slow over ADB, but anything at all is way better than nothing now that you've got hardware to mess with. wink

Re: Resurrecting the USB to ADB adapter discussion

Thanks! I'm focusing on standard keyboards and mice for now. Storage is really out the question - it would require custom driver software on your Mac, and would be at least 10x slower than a floppy disk. Joysticks and things are possible in a future update, but are pretty far down on the list of priorities. My next big priorities are to finish a revision 1.1 board to fix some goofs in the 1.0, and transition to a commercial assembler instead of hand-assembly. Then sleep. Then maybe remappable keys for foreign keyboards, or USB composite devices. And design a case.

Re: Resurrecting the USB to ADB adapter discussion

But just how cool would it be to measure your storage speed in WPM? lol

That'd be called a ResEdit/KCHR resource hack, it's in there for the Mac side anyway. wink

Yes! If I could easily remap the F-Keys on my Saratoga keyboard to control brightness and volume in OS X, I'd be replacing my iMate.

Re: Resurrecting the USB to ADB adapter discussion

The firmware doesn't currently support "media keys" like brightness and volume, but with a little more work it could. But then you would lose the ability to actually type the F-keys, for any software that requires them.

Re: Resurrecting the USB to ADB adapter discussion

Yeah, I've been using Karabiner so I can type on my AEK via iMate at work.

Re: Resurrecting the USB to ADB adapter discussion

Interesting, I wasn't aware of Karabiner. Does it not already do what you're asking for? I see volume and brightness keys defined in their key mappings file, so it seems like it would be possible.
