I just picked up a Quadra 950...well actually it was abondoned by my department at work and in the trash heap. While I love the classics and trully enjoy the "campiness" and "nostalgia", I am wondering if I can have some fun hot rodding this. Does anyone know of upgrade cards to a G series (is it even possible)? What about turning it into a Linux server? Any suggestions on fun things to do?

Hey thanks for taking my advice, and glad to see you here in the 68kMLA!

1. There's no way to upgrade a Quadra 950 to a G3, about as far as you can take it is a 100 MHz 601 using a (rare) Daystar upgrade card. However, trust me, if you use it right a 33 MHz 040 will get the job the done.

2. Yes, the Quadra 950 makes a superb Unix/Linux server! In fact, Apple's Workgroup Server 95, which is essentialy the same as a Quadra 950, came pre-loaded with A/UX, Apple's first version of it's Unix-based OS. Nowadays, A/UX is about as easy to find as Honus Wagner baseball card, so you're better off using a newer Linux port like Minix, Debian, OpenBSD or others. You can find out more at Jag's House.

As far as other upgrades, you can...

3. ...max out the RAM at 256MB, which was unheard of in its day. It uses 30-pin SIMMS, and you'd need sixteen 16MB SIMMS to get that much. They're actually not as rare as they used to be, and you should be able to get four 16MB SIMMS for about $30 (not including shipping) off eBay. Thus, for about $120 you could max it out. Just remember: Always install RAM in a Quadra 950 in sets of four of the same size, and don't even bother buying RAM if it's not the 16MB variety, it just aint cost effective.

4. Put in a bigger SCSI hard drive. One of the amazing things about the Quadra 950 is that it has a SCSI I and a SCSI II bus on the mobo, just like my 7500 that came out years later. The SCSI II bus will support 10MB/sec thoroughput, which is plenty for just about anything that you're going to be doing on it. The SCSI I is 5MB/sec, and will handle external devices. So, try to keep all your speed-intensive devices, namely hard drives, internal. You can put in as large a capacity SCSI hard drive as you want, as long as it's a 50-pin, single-ended 3.5" drive in either 1/3 or 1/2 height variety. I'd reccomend at least 4GB, and you can partition it if you need.

5. Aside from running soem variation of Linux on it, you should have Mac OS 8.1 on one of the partitions/drives. Well, unless you're going to be using a video card that only supports certain System 7 releases. 8.1 supports the newest version of PPP and TCP/IP needed to take advantage of high-speed internet access through an ethernet Nubus card and also custom desktop pics, Kaleidoscope, a much better looking UI over-all.

There's more but I think that should help you for now. That and Firewire is Fast will get mad at me!

Actually, there is a way to upgrade to a G3. However, before you do this, you must replace your logic board with one from a Workgroup Server 9150. Then after installing more ram, you can get one of Sonnet's G3 upgrades for the NuBus PowerMacs and put it into the PDS slot.

Sonnet made a 100 Mhz PowerPC 601 upgrade for the Quadra series, but as I check their site right now, apparently its been discontinued. But a PowerPC upgrade really isn't necessary if you already have a Power Mac. Also for the price of one of those upgrades new (used to be 300 bucks i think...) you could probably get 2 Power Mac 8100/100's

Realistically. Mac OS 8.1 is very snappy on my Quadra 650 (same 33 MHz '040 as you) with 32 Mb RAM and a 1.1gb Quantum Fireball HD. Imagine how well it would do with a large scsi drive on that SCSI II bus and 256 Mb RAM!

but then it wouldn't really be a Quadra 950 now would it?

Here's an eBay auction for a 66MHz 601 that will work in a Q950. I've seen the 100MHz dealies come and go as well.

I have a Quadra 950. I think the neatest thing is the ability to hook up multiple hard drives. Makes it easy to store files or transfer them between drives.

It is also nice in that it runs System 8 fairly good.
