Quadra 950 – how to do a fresh installation? Do I need the original floppy disks which came with it?

Recommended Posts

You can also use retail CDs or floppy sets for 7.5.0 and later.

 

If you have 12 megs of RAM or more, 7.6.1 or 8.0 will also work on this machine.

 

I've got some ISOs you can burn on a modern computer here: http://personal.stenoweb.net/oldmac/

 

macos761retail and macos8retail would be the best images for that. imac233-81 would also work.

Hi,

thanks for replying.

 

I’m getting a Quadra 950 and the owner sells the original floppy disks with Manual apart from the Macintosh. So I’m undecided about buying them too or if I can live without them.

 

As I said my real and only need is to be able to perform a fresh install of the Mac System. (I would like the 7.5). No matter if it can be done using online files or original copies.

 

The question could be put like this: can I do a fresh System 7.5.3 install using a CD and files from the web?

Or, instead, I need the original floppy disks (Install 1 and 2, Printers, Tools etc.)

 

Thank you

A 950 will have shipped with 7.0.1, so if you want that version, get, or find the diskettes for it online. If you want early 7 but don't want to bother finding the 950's diskettes specifically, a 7.1 or 7.1 pro set should work fine.

 

If you want a newer OS version anyway, then other media will work.

 

If you have an opportunity to get the original install media, I personally recommend taking it just because that kind of thing is nice to have.

Yes, I would like the 7.5.3 version...

I could have but I really do not need them. I’m taking the Quadra since I want to develop some programs for System 7. It’s a good price IMO and I would like to take it. The problem is it doesn’t power on!!! Instead I need it in working conditions.

 

I can take a working LC475 for 50% more and a working Quadra 700 for 100% more (than the Quadra 950). What would you do?

 

i’m undecided since yes, I need a working machine, but I cannot spend too much for it!

What are the loadouts on each and what all stuff do you have already?

 

To be honest, the 475 is a perfectly serviceable machine. It's the same speed as a Quadra 700 and it can take less VRAM than a 700/900/950, but it'll still output to an 1152x870 display and you can clock them up to 33MHz, and you can add "full" 040s to get the FPU, which isn't beneficial for much, but it might be beneficial for a software dev workflow.

 

You'll also need to account for an LC-PDS Ethernet card in a 475, which the 700/900/950 have onboard, but those machines also need an AAUI transciever.

 

Other than that, the advantages of a 900 are that it's got a lot of slots, a higher memory ceiling, and a 5.25 bay, which might have a CD-ROM drive in it. A 475 will be able to use an external scsi cdrom drive, however.

 

It's pretty hard to go wrong in this era, but what specifically you want can guide what you might look for. Other good machines are the 630-640 series, which has a CD-ROM drive but can only do 832x624 video.

 

The 650/800 are sort of the successor to the 700, they both support CD-ROM but not all of them have it, they've mostly got onboard Ethernet (there are some 650s without, though) and they have varying CPU configurations, mostly with full 040s.

 

The 840 is also good, slightly faster stock CPU than the others, but it lacks the 950's RAM ceiling and the 800's memory interleaving, so if you want a top end machine, picking the one whose particular go-fast stripes match what you want to do.

 

Overall, of that group, my recommendation probably falls to the 475, provided you either don't need or can budget for adding things you want to it. (ethernet, CD-ROM in particular)

 

If you don't clock it or accelerate it you'll wait longer for, like, builds, or other "compute job" types of things, but day-to-day I don't know that i think you'll notice the difference between 25 and 33MHz, especially in system 7 and especially if you aren't multi-tasking or running background work like a chat or IM client. (For example, I had an 840av in 2002 or so I was using as my daily internet system, with 64-72ish megs of RAM. I probably benefited over a 25-33MHz system because I was running AIM and Outlook Express in the background most of the time.)

On the question of the Q950 not powering on:

 

Check the key position, as it won't turn on if the key has turned it off. It's an unusual security setup, as the machine was intended for server duty. 

 

If I were you and I could buy a Q950 with good prospect of getting it working, I'd go ahead and get one. The Q950 cost something like $10000, which is 900% or so more than the LC475, so there is a sort of cachet attaching to the machine. But you'd need room, as it is a big, Big, BIG machine!

 

If you wanted to develop for A/UX at any stage, then ditto, as the 475 won't run it. Another small thing I've found is that you can make the Q950 run very quietly by replacing the fan; stock, it sounds more or less like a Vulcan bomber (man, were they loud).
