My question: I have two old macs and I would like to use my adb keyboard for both computers. I thought to buy an adb adapter (female/female), connect the keyboard (male) to one extreme, connect the switch cable to the other extreme and connect two adb cables (port A, port C) to the switch, one for each computer. Is this OK or are there some electrical considerations that I sould be aware of?
I really appreciate your help,

Re: 2 cpu's one keyboard (adb)
Yes and no. The good thing is this will work the bad thing is the possible droping of the driver connection which rarely happens, but it is a possibility. Also if the cables use mechanical switching there are galvanic issues that may occur (and opto-isolated switch is better). However this will work. This the basic functionality of the KVM switch.

That Mac has a hdmi port and a mini display port. The monitor has a saga port. So ether a hdmi-svga. Or miniDisplay port-svga.
Any usb keyboard will work. So any Mac keyboard newer than 12 years should be good, and newer pic keyboards will work. Beware of older keyboards that have round plugs. On macs these were ADB ports. On PC's, they used PS2 (ADB, ps2, usb are all different, you want the flat rectangle USB)
U.S. pc keyboards also have two modifier keys wired different than the U.S. Mac keyboards, but this can be adjusted in the system preferences. Can't say for non U.S. KBs. They are the windows/alt keys. Vs Opt/Command keys. That is, if you are soused to using a Mac, the key that is closest to the spacebar (command key) is applied by the second key over rather than the first. Again, this can be modified in the Sys Prefs.
The Macs that you can install windows on need to have an Intel processor. Usually old old macs as you said are using PowerPC CPU.
To check the list of Mac computers that support installing windows (BootCamp) , you can check this list: http://support.apple.com/kb/ht5634
As for the part where the Mac won't start up. This depends on it's a hardware or software issue.
The solution is not a download as it all has to do with the type of mac you have. Newer macs have an intel chip on them, yours must have a powerpc chip.The only way to get an intel mac is unfortunately to buy a newer mac.
I'm thinking this is a Mac-only tablet. The ArtZ II for Windows came with an rs232 (old mouse) port at the end of the cable, in addition to a built-in spot where the power plug attaches.You didn't mention the power plug on yours, so the Mac version of the tablet must have the power routed in through the cable.
Short answer, the reason the light isn't coming on is because the tablet isn't receiving power. If you go get a cross-platform adapter card for plugging in Mac hardware on your HP, it *might* work.
This unit does not have USB ports only discontinued ports called ADB, they look exactly like S-video ports, that is where the keyboard or mouse goes, PC keyboards do not work in these ports only specific ADB keyboards and Mice will work here. If you need any more info on the connectors feel free to ask me
