Re:The Apple ][GS battery:
I was wondering why the GS would have the control panel settings backed u p
by a battery and not an EEPROM which I assume wold hold the data longer and
wouldn't need to be replaced...

I'm not sure, but I think that it is cheaper to use a battery.

If they did that, they couldn't charge you an arm and a leg to replace the battery, now, could they? # include <std.disclaimer> ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ ___ ____ ____ ____ _ | \ | \ /\ / \ / \ |\ | GreyMan ----> and the <---- | \ |___/ / \ | ___ | | | \ | / \ | / | \ /====\ | | | | | \ | |___/ | \ / \ \____/| \____/ | \| Kurt Miles ..... remember, sometimes the DRAGON wins!

Well, for one thing, EEPROMs take a *long* time to write to - upwards of 100 milliseconds or so. Compare that to the 150 nanoseconds it takes to write to RAM. The computer would have to come to a complete halt (well, almost) just to change the control panel. The BIG loss with EEPROMs is they can only write a hundred or so times. Then they go on the fritz. If you're the type who sets his machine and that's it, then EEPROMs wouldn't be a bad idea. But it would be costly for those who like to change things all the time as they'd have to change the chips every now and then.

You'd probably have to replace a EEPROM before you'd have to replace the current //gs battery. -- Matthew Lee Stier | Sun Microsystems --- RTP, NC 27709-3447 | "Wisconsin Escapee" uucp: { sun, mcnc!rti }!sunpix!matthew | phone: (919) 469-8300 fax: (919) 460-8355 |
