68k systems
Just a couple of quick questions

What is that most recent OS that will run on a 68k Mac (quadra650)?
Also is it available from apple as a download?

Thanks

8.0 was the last 68k OS, 7.5.5 is the latest you can get from apple

Actually it is 8.1 (and worth the bug fixes). I have an old Centris that runs 8.1. If you install just make sure you initialize your disk as HFS and NOT HFS+! There are still plenty of unopened OS 8.1 retail copies out there. Check eBay. 7.6.x was a good version and may be a little zippier on your machine, although not as pretty as the Copeland style 8-8.1.

I saw 8.1 running on a Quadra at my old college and it was actually pretty smooth - I thought it'd be choking along on a processor like that - it could even get on the internet

One of my four Macs is a Centris 660AV using 8.1 - rock solid.

Used it on the internet for six months with a Global Village 56k
v.90 modem.

I was running 8.1 on a Quadra 840AV (fastest of the 68K Macs!) for the past eight years. I finally upgraded when Apple introduced this sweet new iBook, and I'm very pleased. But I'll tell you what ... that ole' Quadra was running and doing just about everything I asked of it for the entire time I owned it, and I defy anyone to show me a PC that can still operate after almost a decade of use.

Anyhow, 8.1 was the latest OS that will still operate on a 68K machine. Of course, you knew that already.

Check out http://www.info.apple.com/support/ol...warelist.html. The system software is 1/2 to 3/4 of the way down the page. I saw System Software 7.5 and other updaters in the list. I may have missed 7.6.

I think I was using System 7.5.5 on my Mac Plus maxed out with 4 megs of RAM. Nice! Even ran Photoshop 2.0 LE, ClarisWorks 2 and MacWeb 2.0. Zip drive plugged in as my system disk... it was cool!

Now that Mac Plus has been in storage with a friend for six years... and I don't know what shape it's in these days.

I even had one of those Kensington fans that fit on the top.

Veering off topic somewhat, can 68k only programs run on a PPC (Power Mac)?

Sure, but they run in emulated mode, which is MUCH SLOWER than native PPC software. Basically, the early PPC machines had to emulate a 680x0 in ROM, very slow.

7.6 isn't available for free, yet, but 7.5.3 is and the update to 7.5.5 is a really really good idea. The update from 7.6 to 7.6.1 is available as a download, and it's really worthwhile.

Places like nexcomp.com have the 7.6 CD for sale, and then you can download the update from Apple. The update is especially necessary for 68k machines, since there were several extensions/enablers which were incomplete when the retail version of 7.6 was issued (oops).

OS 8.1 runs great on my Quadra 650 (with lots RAM), but not so fast on my 5300 powerbook. I run 7.6.1 on most of my old machines. With a PB 160, I'd try to find the necessary files to run 7.1, since that machine tops out at 14M RAM and it's really hard to put a later OS in RAM and still have headroom for applications. Plus, you can replace HD with smaller ones when you need to, and use the machine as a basic word processor for years to come. An 80M HD does great with OS 7.1 and a word processing package, and maybe AOL 3.0 if you have a modem, and the 80M HD are still cheap and plentiful (SCSI 2.5" hard drives are somewhat hard to come by these days).

Yep. I've got one that I still use with a creator date of 1984.
