New project. G4 6500. :)

PPCMLA OS 9 8 posts Feb 1, 2010 to Feb 2, 2010

I picked up G4 7200 upgrade from Sonnet on clearance before they were all gone. My goal is to be able to fool it into working in my 6500. It sits in a PCI slot and has it's own RAM slots which means I can upgrade it beyond the 128mb limitiation built into the 6500 if it works. It only supports Mac OS 9.1 but OS X doesn't work well on these things anyway.

So, will it work and where should I start in trying to fool the installer into thinking my Mac is a 7200 instead of a 6500?

So I found an Apple Lisa in GA!!! It arrived today... Needs a good cleaning and some cap repairs and stuff... Widget is dead for sure.. I can hear a piece of metal just loose inside rolling around.. Anyway.. what is odd is the serial number off the keyboard is scratched off and the serial number off the unit is removed.. I can see the residue left over from the serial number on the unit...

I remember at one time reading a post or someone told me that someone at one time broke into their house and stole a Lisa and some other stuff.. this would be strange but perhaps this is the one??? I have no idea why one would scratch off the serial number on the keyboard and take the sticker off the unit...

Does anyone recall that post or that person??

Good question! That would be interesting if it works, though the L2 cache slot upgrades for 6360/6400/6500 are pretty damn speedy and would be my first choice...

You might need to use something like "Wish I Were" to change your Mac's gestalt ID to get the software to install. You could also try using GestLab is Wish I Were isn't modern enough.

Peace,

I have never heard of serials being removed in such a manner, even when upgraded to an XL. So that is a bit odd. But being a Lisa no upgrades would have been done in such a way in the first place.

There's an old thread on that other forum where I detailed my attempts to use a 7200 card in a 7500. I believe it worked OK.

I think my 7200 card is faulty though. It would freeze up every 10-15 minutes running in the 7200.

Congrats on the Lisa!

What you believe to be a piece of metal rolling around inside the widget drive is actually a piece of glass. It is a piece that calibrates the head to tell it where it is, basically. Since the drive is toast without it, you might open it up and see if you can glue it back in place. I had one that broke off but I have heard that others had just fallen off with age because of the glue they used. For the record, I couldn't get the piece glued in properly. If you are able to glue it in, you might have to low level format the drive to "recalibrate it".

See what damage the glass has in the drive first and take it from there. Normally you wouldn't open a hard drive but it's "toast" anyway so why not try to McGyver it back to life... even if it is probably futile?

Thanks for the advice.. I may give it a shot..

I've opened hd's before and got em to work... Forgot about the glass thing.. Wish me luck!!

Hmm. Actually, I don't recall ever seeing a G4 L2 upgrade... I have a G3/400 and a G3/500. One is in a 6500 and the other is in my TAM. Both are really fast. They feel much faster than they should, and they (subjectively) smoke my G3 upgraded PCI Macs. I haven't done any benchmarks to figure out if my perception is accurate.

Peace,
Drew

I bought it more for the possibility of being able to upgrade to more than 128mb. than for Altivec. There were ebayers selling the G3/500 model for the same price as Sonnet was selling the G4/500 models for at their site so I decided to grab a G4 instead.
