Here's a tough one.
Has anyone managed to adapt USB to their 68K macs?
I am running several LC-475's as well as color classics and a couple of Lc 111's.

Thanx Folks

The short answer; it's impossible.

Yeah, about the only thing you can do is ethernet/appletalk your way to a Mac that does have USB, and share the device (assuming it's a printer or something that can be shared)

A little knowledge is a dangerous thing, but it sure beats a blank stare for starting a conversation.

I wouldn't say it's impossible, just highly unlikely. If someone wanted to actually make a NuBus USB card, a 68k mac with 8.1 could take slight advantage of it with Apple's drivers they had for the first iMac. And more drivers could be written I'm sure, but that requires work, and no one likes to do that when they can be doing other things, so I guess it is kind of impossible....

USB bridges are getting more flexible, more powerful, more intelligent and less expensive all the time. I'm certain there will be USB on 68k Macs at some point, it's just that the 68k Mac won't have any idea that it's dealing with USB, it'll look to the system like some other kind of I/O like ADB or serial thet it already knows how to deal with and use existing system drivers, but I'm sure you'll be able to use a USB KBD/Mouse/KVM switch to run a 68k Mac eventually.

There's a thread from about a year ago over on fritter on the subject, references to it and a sister thread over here too if you search!

I wonder why... Is the bus on the 68ks not fast enough?

If Apple wanted USB on 68k, they'd put the routines into an OS patch to deal with it. They wanted to sell iCrap and BlueBoxes to make money, not waste development resources to extend the useful life of BeigeMacs with bronze age CPUs.

It's funny -- they certainly were part of the bronze age compared to iMacs and all, but the original iMac did only ship w/ 8.1. Certainly, it was an 8.1 with some nice enhancements (like USB!) but the same system overall. There was a lot fo 68k code left in it!!

This is a guess based on my study of "Designing Cards and Drivers" (NuBus): I think the more important break between generations was probably between the NuBus and PCI based slot manager architectures, not the CPU generation directly in this instance, at least when it comes to i/o implementations.

I regularly used my iMac CD to successfully install OS 8.1 onto my Quadra and Performa....


isn't there USB pcmcia cards?
doesnt the 190C have PCMCIA?

isn't this exactly the same to what happened with 802.11 for 68ks? it worked?

Nope, 80211b uses the same drivers/I/O ports as wired ethernet NICs, there's no similar provision for USB. A bi-directional USB<->SCSI adapter might allow for hacking something. Maybe a Hurdler serial card could be hacked to make a single device work like a serial port device, dunno, keep thinking about it, maybe you'll come up with something. When I looked into it in cinemo's fritter thread, the USB->i2c bridges looked good, there might be a way to feed USB stright into the ADB controller via i2c, but that's a long shot.
