If you need to replace it you would start by getting the old fan out and looking for data about it, then seeing if you can find something comparable. Be careful though as not all manufacturers use the same methodology to come up with their numbers.
I seem to recall those machines using a size...
Okay, 128K disk cache this time.
Power Mac 6500 225MHz, 256KB L2, 136MB RAM (64MB + 64MB + 8MB added onboard), CSII NIC, onboard GPU, no PCI cards. Running a fairly recent install of Mac OS 9.2.2 on the BlueSCSI for some consistency between runs. Virtual Memory and AppleTalk were off.
SD adapter...
Just did a quick run with the CF card and 128K disk cache, sequential numbers all stayed the same but the random read and write dropped to equal or slightly best the included PowerMac G4 500 result. I will try to retest everything tomorrow.
At this point most of my cards are Verbatim and were from Amazon. The painful part these days is the price for anything more than 16GB and that is unfortunate.
Perhaps someday I will retest everything with a different program for a bit more detailed info.
If I recall I was having some weird...
Yeah, I have been testing some things in my 6500. For all the excitement people have about SD and SATA adapters in old Macs, I still would rather use CF cards if I can get my hands on them.
This is pretty normal even with original logic boards, I don't recall the details but I do seem to recall that older Macs were notorious for not retaining their serial numbers. Someone else certainly knows more.
Don't sweat it.
I went through this issue not too long ago and have a stack of non-bootable discs to show for it. Eventually someone pointed me to some images posted to help out BlueSCSI users and those worked.
Another thing I have noticed over the years is that with my particular PCs and drives, burning at...
Typically these days I use Verbatim CF cards, but I recently have played with a generic SD to CF adapter in a search for more cost-effective storage. It is currently the boot device used with my 631CD board. I have Mac OS 7.6.1 installed and had to use the APS PowerTools driver for it to be...
I have never met a 630 or 580 board where that pin was actually connected to anything, and over the years I have regularly used them with 6500 chassis harnesses and PSUs.
On my 630 that pin is not connected to anything I can find. The top and bottom are not even connected to each other. I used to run 580/630 in a 6500 chassis with no mods and never had any issues as well.
I gave this a shot on a 6500, and then removed all ATI-named extensions and ran the Oct 2002 installer.
However I am not getting very far into the first demo. I tested Quake RAVE first and it froze before the console slid up, OpenGL was no better.
As for the games bundled with the 6500...
It would be neat if some of the firmware gurus around were able to figure out the whats whys and hows related to the extra RAM.
Beyond that, if you are curious to try it then by all means add the RAM to your board!
I would imagine there are not too many 6500/5500 boards in this world with 136MB...
To say that you have done it, and cause future headaches down the road when the chips you added start failing. Also to do it on the slowest board in the lineup you have access to, so that you further waste the effort on something that can barely run the software it was bundled with in the first...
