From the ANS Hardware developer Note
From the ANS Hardware Developer Note:
So interleaving is not disabled, but the ANS runs the memory bus at a lower speed. It also sounds like the ANS will accept 128MB DIMMs. But only four of them. Sorry about the mislead about 64MB being the maximum.
I posted all the documents I have in my archive regarding the ANS. They're here:
https://www.prismnet.com/~trag/ANS/
I don't know if there's anything there you guys don't already have.
Interesting (to me anyway) I have the PDF instructions on how to install 4.1.5, but don't seem to have the update anywhere.
It occurs to me that we should check with Cameron Kaiser. If anyone has the 4.1.5 update it would almost certainly be him. He was crazy for the ANS for years.

I put a watch on it. When I get a 10% off offer I'll buy it. Thank you. I appreciate. I guess I need to get the magic ROM code too. I don't suppose that you have a chip programmer with which you can read the contents of that magic chip?
A modified New World ROM at a minimum.
The interrupt signals in the ANS are wired differently than how they are in the PowerMac 9500. I don't know, but I'm pretty sure the ROM contains information that maps the various interrupts directly to specific PCI slots and devices. On the ANS, that mapping is scrambled. So if one installs a PM9500 ROM in teh ANS at some point the ANS is going to grab the wrong interrupt handler.
Apparently at boot time according to reports of folks who have tried it.
The 2nd paragraph is informed speculation. The third paragraph is what I remember folks reporting.
Sorry, no. I can see if someone I know does. Would be a good thing to have. If you have any suggestions, please let me know.
I have a c hip programmer but I'm always uneasy trusting rare/unique content chips to the various delivery services.
We have a member in the UK who persuaded a US outfit to loan him a PEx ROM and PLCC chips, and then UPS lost them in transit. Happily, there was a UPS employees forum where he was able to ask for help and a very kind employee hunted down the missing package. But sheesh. All hair standing up at attention.
Anyway, I'd be happy to make copies, but again, risk. I'm in Austin, TX, BTW.
I compared my RAID card to the one in the eBay listing and it appears to be almost the same. While the card in the listing has the two ROM sockets populated, the Apple card only uses the one. Would removing both on the new card and only putting one in on the new card be a problem? Don't know... If I were really wanting a RAID card these seems like a cheap bet assuming we can get the Apple chip duplicated.
So just to circle back... I have inherited another 500/132 and a 700/200... Very excited.. The other 500 has the SCSI raid card and all the drives are in it. That machine had a DAT drive in it. It is an HP 1533 DDS2 Apple blessed with the sticker. I'll take a pic at some point for you all. Anyways it took me days and hours to get this drive back up and running. First when I disassembled it I discovered 3 10uf 16v caps so I replaced those. Next by searching the internet I found there is a little foam cylinder that will occasionally clean the heads.. Well after touching the foam it just disintegrated. On line it was recommended that it be removed. So I removed it! It's not really needed. From there it took me about 2 tries to gently clean the head going in a circular motion very lightly with 99% rubbing alcohol. It was dirty.. probably from that stupid decaying foam cleaning wheel. So I ran a DDS cleaning tape and then put in a brand new DDS tape and whala! It's running perfectly!!!! I'm shocked I was able to get it up and running! In my opinion I've always hated tape backup drives!!! But I wanted to have a working one on the ANS. Here is a photo with the hidden caps under the main board. They are those angled one's that appear to be tantalum but are not. They are encased in a plastic little thing. I'll update y'all on the actual photo of the drive where the label is.. I'm running a full backup right now.

Ok so I know you all have been talking about the SCSI raid card. Here is mine. I removed the daughter board with the battery on it.. that’s all I need is for it to leak. Question: does the scsi raid card require this daughter board? Can I peel off the battery and put it back? I realize it’s just so it saves the read/write cache.. but I’m not sure if it is required.. I expect no..

I don't have any way of knowing if depopulating one socket and replacing the other with the Apple chip would create issues. I think it is worth a try.
If anyone wants to risk (misdelivery risk, fairly low, but non-zero) sending me their Apple chip I will make copies for everyone. Actually, a good first step would probably be to read the markings under the sticker on the Apple chip. Doesn't do any good to try to make copies if one can't find blanks.
Although it is entirely possible that any same-sized flash/eeprom will work.
Here’s what’s underneath the sticker. This is the IBM chip I replaced with the Apple chip

Hey gang.. a little help. Can I remove the battery from the SCSI Raid card? I will keep the daughterboard it's on installed on the SCSI Raid card because it's required apparently after reading a bit. I just don't want to leave a battery in a machine that could sit for a period of time. I am assuming it's just a cache battery and doesn't hold the configuration of the raid yes??? If it's just a cache battery I don't care and I'd rather remove it.
I assume you mean the one that plugs into J2? As far as I know, it should be OK. My card has a little card that plugs into that header. I'd have to see what pins (if any) it bridges together.
in theory you should be able to boot OS X directly on an ANS without any need to swap ROMs since the ANS does run OpenFirmware
as OS X bypasses any need for a Toolbox ROM image and boots directly from OpenFirmware including on OWR macs
the only things you would need to do is figure out what NVRAMRC patches an ANS would need, being technically and Old world ROM machine im sure will have plenty of OpenFirmware quirks that need patching before OS X will boot, like all other OWR macs need
and then add the ANS model identifier to the plist in the PowerSurge Platform expert kext for OS X (since I dont think its there by default, but I know the ANS is very similar architecturally to a 9500 so id like to think the same platform driver would work)
then in theory it should boot... (although if your trying to run Later then 10.2.8 you will need a suitably patched kernel like my 604 10.4.11 kernel)
I have sadly not see anyone try, but it would be fun to see someone try

Beside of this, one of my ANS seems to have a broken mother board. Power up by keyboard and front switch is working. But no start chime and no status messages on the LCD. Capacitors replaced. RAM,ROM,CACHE changed with parts from working one. Any ideas what I might could check further?
