Anyone have a idea as to how the IBM keyboard would interface on the Apple
IIgs? Seems that one would just have to figure out how the ADB works, then
'wire' up the connectors, no?

ADB is more then a couple of wires; it is a *VERY* local area network. There is a whole protocol involved that has the host query devices attached to it. There are several commands involved that use several registers. In effect ADB devices can also be programmed into modes. To handle all of this, we designed and put ADB controller chips into our keyboards and mice. So it sounds like this is more than just a weekend task. However, it is not beyond the reach of possibility that some hardware developer can or already has done this. ------------------------------------------------------------------------------ Keith Rollin --- Apple Computer, Inc. --- Developer Technical Support INTERNET: keith@apple.com UUCP: {decwrl, hoptoad, nsc, sun, amdahl}!apple!keith "Argue for your Apple, and sure enough, it's yours" - Keith Rollin, Contusions
