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?

If this is really the full 4.1.5 install of ANS AIX 4.1.5, you are my new best friend

Unfortunately, I'm not sure what to tell you on your non-booting server :-(

He will be my best friend too.. Perhaps I can give you a hand with your issue... PM me directly. I am trying this CD right now.. The anticipation is killing me..

Looks like 4.1.5 to me in the install process!!!! And the full install!!! You have made a lot of people happy
"wymtb" Can't thank you enough... I'll do what I can to help you out with your server...

Hi from Norway!
I just registered to this forum just to say THANKS to the person responsible for sharing the 4.1.5 image.

I’ve been pulling my hair and chased my own tail for years due to a bad dump of 4.1.5 that I received from somewhere else.
Always ended up with a default catch fff00700, although it was claimed to be a verified dump.
Linux (Yellowdog and slackppc) and 4.1.4.1 would always run without issues.
At least I have a veeeery clean ANS after all the diagnostics.

Not only did my 700/150 (the only one in Norway?) for the first time install 4.1.5, I also got the dat tape streamer to work again today, after years of deteriorating «cleaning»sponge and dirty tape path.
The pinch-wheel and clogged heads was the main culprit.

Next issue is finding someone with access to a dump of the long lost apple ftp containing the 4.1.5 patches.
I’ve heard rumors of it being archived somewhere.

Give me a shout if you know such a person!

Have you already found this ?

I probably should do some work on mine...
Anybody who has the tray or front bezel for a DAT drive please let me know. I have the bare drive.

Hi I recently uploaded this service guide and it wasn’t anywhere online it covers the 500 and 700. Link Here

Sorry for the late reply. I haven't been checking back here in a while. Too busy.

I repaired an ANS logic board many years ago, and the problem it had was a bad inverter. Just a logic inverter. It was probably a dual or quad inverter because it was in an SOIC or similar package. Not just a little 5 pin thing.

It's between the Clock signal that comes from the CPU card and the clock buffer chip which is on the logic board. I'm sorry I'm not more specific. I might be able to find it, or the region if I had an ANS in front of me. I did this repair about 20 years ago or maybe more.

I don't know if that's a common failure mode, but it fits the symptoms you're seeing.

AFAICT, this inverter just cleans up the clock wave form before it hits the clock buffer, which splits the clock signal off to all the components that need it. It can't be there for timing, because everything takes its clock from the downstream buffer, so everything is adjusted the same amount by the buffer. Even the CPU gets it's signal from the logic board buffer. The raw clock comes off the CPU card, goes through the inverter, gets split by the clock buffer, and then comes back to the CPU card as well as out to the logic board components.

Also, do you have another CPU card to try? Have you cleaned the CPU heat sink grease and replaced the heat sink compound with new stuff? The original has almost certainly turned to chalk by now.

FYI.. I gave Techknight an ANS battery bombed board I had... He might be able to rob the particular chip you need off of it?

 

[ScutBoy]

I also have a bombed logic board (and maybe still the CPU board) and would be happy to pull components.

I have basically all the internal parts for ANS machines if anyone needs anything. The chassis and external plastics have been claimed, but I salvaged the rest. The power supplies show some outside corrosion damage from the battery failure, so I don't know if they can be trusted, but the rest should be OK. Floppy drive, drive sleds, internal cabling, power supplies, etc. I think the CDROM is there, but i might have used that someplace else.

If you two are referring to my post about the problem possibly being a bad inverter, the chip in question is a standard logic chip. Something like an SN74HCT05 or some such. Otherwise, apologies for interjecting.

One should also note that most of the rare Apple specific components on the ANS board can be taken from PM9500 boards, except the DPATH chips, which are different on the ANS, probably because of parity support.

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.

Trag I’m thinking of taking my chip out and getting it duplicated. Besides delivery worries would you be able to safely duplicate? I’ve got a GQ-4x4 programmer myself I would just need to get the adapter to read it. Of course if I do it I’d share the chips file with everyone

I’m assuming this adapter would be the one I need?

Also (sorry for all the replies) I’d need to know what kind of chip that is to buy blanks… I’ve done eprom burning before but have never worked with that kind of chip tbh.. a bit rusty since I don’t do it that often.

 

[aplmak]

Sorry duplicate

 

[aplmak]

So it looks like it is a 32 pin PLCC blank chip I need... any idea on what one I would need to get? I still might just send this to Trag but just out of curiosity..

Wrong adapter... I did find and get the 32pin I need...

 

[aplmak]

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.

Scutboy I think I am going to try to give this a go. Got the programmer the PLCC chip remover.. and getting the EPROM 32 pin adapter. I just need to know what blank to order. Once I read the chip I'll upload to here the bin file for it for everyone. We'll see how I make out.. i might end up sending to Trag I dunno. But help on the blank chip would be appreciated. I'd have to peel the label off mine to see what model chip it is, unless someone knows...

 

[ScutBoy]

I sent trag the Apple specific ROM chip from the RAID card so he could dump the contents. If that's the chip you are talking about, you'll need to get ahold of him...

Oh awesome that would save me having to remove mine and then reading it and possibly damaging a good card!!! Thanks Scutboy for everything!

Can confirm I'm using bog standard 5V DIMMS from Macs of the era in my ANS, 512MB with no issues.

Again, sorry I've not had the time to wheel out my ANS yet to confirm all the stuff I've been saying.

Byrd not to drag on again about the memory thing.. but that Memory Masters increased their price to close to $50 per DIMM now. But what doesn’t make sense they also sell I’m thinking the same thing for $25.00 but specifically labeled for the PM8600… I’ve got both machines and the memory looks extremely similar. Put aside all the parity stuff.. they are basically the same thing 64MB FPM 168 Pin DIMM’s. I’m not sure why they have two different listings.. I did notice the price increase after I bought a bunch but they have more than 10 available..
