Apple Network Server 500/132

Well she’s up and running.. the dat drive I have installed properly but it’s having write issues.. need to get a replacement. I hate DAT drives.. they can be very finicky and the capstands tend to go.. I have a Wangtek in my Altos Xenix server and I had the capstan roller rebuilt. I know u really don’t need the DAT drive I just wanted to make her complete

On my HP DDS DAT the plastic of the spindles has split and they pop out since there's a spring under them.

This is the nicest looking ANS I've ever seen! Congratulations on an absolutely amazing acquisition.

Thanks circuitbored! It took some work!!!

So I recapped the MLB for the ANS server. There were only 13 SMD caps.. 2 - 10uf 16v, 3 - 100 6v, 8 - 47uf 16v. I've done this on some other 90's machines I have... I am all about preventative maintenance, and I'll just forget and they will dry out or leak at some point. At any rate I replaced them with good quality APX Tantalums. What doesn't make sense is there were other tantalums on the board with the same values... a little larger.. I wonder why Apple used SMD electrolytic?? Is there a reason? Or was it a cost cutting thing?? Any ideas? These are not huge caps so I don't see the issue with using the tantalums.. Most servers use tantalum at least some that I have worked on for reliability I would assume since it is high end. Just wondering about what everyone's feedback on this is....

I noticed the mix of tantalums with electrolytics on that board. I've seen it on a few other Apple boards as well. I'm sure there was reason, whether it was a good or bad one, who knows...

 

[aplmak]

Well I switched mine out with Tantalums and it’s humming fine.. I’d rather do it now and before I forget and years down the line they dry out or worse leak!
The amount of Mac Portable boards and SE/30 and classics I’ve done just shows what years of sitting smd electrolytics can do…

Having just finished my Portable and Color Classic projects I guess I should look at the ANS board for recapping. As you say, an ounce of prevention...

Is there a pick list for the electrolytic that you can share ?

While I'm in there I guess I can try and figure out why one SCSI bus doesn't show drives that are there. Used to work and thought it might have been the Raid card gone bad, so as someone else noted, I found the non Apple version and transplanted the ROM. Sadly didn't fix it but at least I have a mirror card now ;-)

Sweet - ANS owners of the world, unite!

I think I picked this up about 25 years ago (along with a Color Laserwriter) when I was in the UK. Allegedly it came out of Apple UK in Uxbridge and hence was loaded with every drive sled (internal round the back too) containing an HD, twin PSU and a full rack of RAM and the RAID card. Only thing I don't have is the DAT drive but I'm not overly bothered. In the past I had YDL and NetBSD running on it for a mail and web server. Fun fact it is a lot quieter than an XServe I later added to the collection ;-)

 

[aplmak]

Nice!!!! The Main Logic board should have the following capacitors: (9) 47uf @ 16v, (2) 10uf @16v, (3) 100uf @6v, I have also done the processor board.. those are ALL 47uf @16v.. I can't remember how many.. Like 12 or something.. I would expect the same for the 200mhz board.. again I cannot over say it enough to leave out the PRAM battery... I can see them needed when in actual production use servers... But there is really no reason to have them in there now.. They are just a problem waiting to happen.. And we all forget to remove them if you do put one in.. lol

Would one of you kind folks please share the specs/model number of the Mylex card? I can't think of any reason I need one or what I would do with it, but if they're still available out there, there's this feeling that I should get one before they disappear.

Let me dig up my notes

IBM 07H1059 MYLEX D040351-0-IBM PCI RAID 2 CHANNEL ADAPTER 07H1058

This is the one I bought. Let me look at eBay when I get to a real computer tomorrow and I’ll see what they have. There are a lot of variations in these cards and I can tell what at least looks correct.

Thank you. Much appreciated.

I checked the disks that were given to me with my ANS and didn't see a 4.1.5 update. I do have a Legato disk, which is certainly tape software. I don't know how useful it would be. I suppose I should photograph the disks I have so you can assess.

 

[aplmak]

Trag thanks I have that same cd set with the Legado. 4.1.5 would have been a later offered cd to people way after the fact. Thanks for checking though.

I do have another memory question! So I have found 5v ram that works.. and everything is fine. The only difference is it is Non-Parity where the server asks for Parity DIMMs. Non-Parity will work but from what I read it just disables interleaving. I mean is there a huge performance increase between non-parity and parity on this old 604 running at 132mhz? I have 256 mb now installed.

 

[ArmorAlley]

What is everyone running?
AIX 4.1.4? 4.1.5?
NetBSD ?
LinuxPPC ? (linuxppc.org is no more :\ Hope it and instruction is still available somewhere)
MacOS ? (supposedly possible with a 9500 ROM and a particular graphics card, but the internal SCSI and RAID card won't function. If ever there was a machine that needed a custom ROM, ANS is one.)

Just curious, what would be needed to run NEXTStep or possibly even Mac OS X 10.0/10.1 run on an ANS? A New World ROM?

I'm going to say that yes, there is probably a performance difference, but in everyday use I don't know if you would notice anywhere else other than benchmarks.

If you were in the '90s running real workloads through this guy you might be able to tell some difference, but I, at least, wouldn't worry about it today. Having more RAM that's non-parity to me is better than having less RAM that is

Thank you. Much appreciated.

@trag - This looks like your best shot currently on eBay. It's the bottom socketed chip on the lower left near the battery and card edge connector that holds the magic - or at least it did for me. I replaced that one with the chip from my ruined Apple RAID card and all was well.

I see a couple others on eBay that are the similar model but they don't have the second chip next to the said ROM chip. Not sure if that's significant or not - I'd have to pull out my ANS and see if that's populated on mine or not...

Hope this helps

PS - I put a "watch" on this card - listed at $29 and just got the "Seller offers 10% off!" email from eBay
