Maybe I'll try some other settings and test at what maximum speed the module can run and then conclude for which speed it was meant. Or maybe I remove the heatsink and check if the speed is readable on the dies. At least for PowerPC 7450s it looks like their meant speed is readable on the die.

I now checked the CPU dies and they seem to be meant for 1600 MHz:

powerlogix-powerforce-7447.JPG


According to PowerLogix (1, 2) this could be a speedy module, because they seem to have overclocked parts by 300 MHz or so.
I currently test the module with 1933 1866 MHz (according to this configuration table which could be wrong at the 1933 MHz line, as all previous steps were 66 MHz steps, so the next step after 1800 MHz would be 1866 MHz, which would be close to the value the system profiler reports) using openssl speed -elapsed in Mac OS X 10.5.8.The system profiler shows it with 1.87 GHz, but I'm unsure if this is correct, because when configured to 1800 MHz it showed 466 MHz instead.

Next stop: 2 GHz! Let's see...

...sadly doesn't work with the stock heatsink and fan :( . Mac OS X 10.5.8 doesn't finish booting. So back to 1866 MHz. But compared to the 1333 MHz I used in the past - fair enough! :)

EDIT:
Looks like I finally found the manufacturer info about my module. It's rated for 1800 MHz by PowerLogix, so maybe I should go back to the 1800 MHz I tested earlier, although the system profiler than shows a wrong speed.

A cluster of mac-mini: four units! Two are PPC-G4, Two are x86-i2.
It's useful to test&compile and to cross-compile for PowerPC-40x.

I'll jump in, all my Macs work (well they did when last checked - these days a few weeks of no use can change this level of reliability!), are recapped where required and I like to collect "best of breed" Macs, with the period correct peripherals and upgrades like max RAM/ accelerators/monitors.

Main macs
- Mac Pro 3,1 - a recent $53 eBay score, upgraded to 8x3.2Ghz Xeons, 16GB RAM, SSDs and GTX 660 graphics (soon to find a cheap GTX 680 for it)
- iMac 27" 2011 - $100 Facebook marketplace score

68K
- 128K
- Plus
- SE/30
- Colour Classic - one a "Mystic" LC575 and high res modified, the other a "Takky" 6500/L2 G3 400Mhz and high res
- IIsi
- IIfx, AST Nubus 286 boards inside
- LC475/Quadra 605
- Quadra 950
- Quadra 840AV
- Powerbooks: 100, 180c

PPC
- Powerbooks: 5300, Kanga, 2400c, Duo 2300c, iBook 12" 1.42, Powerbook Ti, Powerbook 1.67 15", Pismo G4
- 7100
- G4 Cube - probably my most used Mac over the years, 1.4Ghz Gigadesign G4
- Twentieth Anniversary Mac - bought on my honeymoon in the States :)
- G4 Mini overclocked to 1.8Ghz
- G4 MDD dual 1.42
- Xserve G4 dual 1.33

... and probably a few I've overlooked.

Have you ever tried Debian for m68K (from Debian Ports) on these three machines? They have a recent Linux kernel available. I believe it works well on ARAnyM. Would be cool to also see this running on 68K Macs, although it might not be that useful when you consider the hardware resources available on these Macs. There's a video available that shows a LC475 (w/MMU) booting a Linux kernel v3.12, though I don't know if this is related to Debian:



...but it shows that a "recent" Linux kernel can work on this type of machine.

More like a glossier version of Craiglist, usually invite only. Friend spotted it, it had a known bad (and recalled) 1TB HD, seller went and got a new one. Was a good win.

I don't know about Byrd, but I regularly run NetBSD/mac68k on a IIci (24/7 internal DNS, printer and power failure server) and a Q605 upgraded with a full '040. They're great for this purpose.

My other "Unix 68K Mac" is a clock-chipped Q800 running A/UX.

Nice! NetBSD again! :D

Just had a quick read on http://wiki.netbsd.org/ports/mac68k/...

Can one automate the boot of NetBSD on 68K Macs, i.e. make the BSD/mac68k Booter autostart after System 7 (?) has finished booting, so that the machine boots right into NetBSD without user intervention?

At what clock rate are you running it?

Long ago, sometime in 1993, I requested info material from Apple about their machines at this time - I wanted to move away from an Amiga 500, though I still have her - and the Quadra 800 was one of my favourites in their brochure - later I discovered the Quadra 700 which was equally nice, maybe a little more :) . I can't remember how often I ran over the pages of the info material and gazed on all these cool and different looking machines. At that time they had the following machines available in the brochure IIRC:

  • Classic II (and maybe also Color Classic)
  • LCIII
  • IIvi and IIvx
  • some Performas
  • Centris 610 and 650
  • Quadra 800 and 950
  • some PowerBooks (which didn't interest me that much at that time)

Well, in the end I went for a i486DX 50 based machine because of all the gorgeous games (256 colours) available for PCs :oops:...
...and of course also because of the premium price of the Apple machines. For the price of the 486 based machine I would have gotten not even a Centris I believe.

Never had the opportunity to get one - neither Quadra 800 nor 700 - since then. But if the 68K Macs run NetBSD and maybe also GNU/Linux - I might start looking again...

System 7 and up has a Startup Items subfolder inside the System folder that gets autorun. You could either put an alias to the booter application inside it, or an Applescript that creates a cancel dialog and waits a few seconds, then runs the booter.

What robespierre said -- that's exactly how it's set up on my IIci (an alias to the Booter in the startup items folder). The Booter has a preference to autostart, so the whole thing now comes up automatically because the IIci's power switch can be locked in power-on. After power up System 7 runs the Booter automatically, which automatically boots the NetBSD kernel, with no human intervention required.

For that matter, the Applescript idea is unnecessary too -- the Booter can be configured to pause a couple seconds to allow you to hit Cmd-. to abort the boot, and if you don't, it continues.

The Q800 is clockchipped with one of the Newertech oscillator clips to 40MHz, which is a nice safe speed that everything (except the PowerPC 601 card I never use) works at. I could drop the CPU to 38MHz and boot it on the PowerPC card, but where's the fun in that? It can be clocked higher but this seems to work just fine and is definitely faster than stock. I personally think the Q800 is very competitive with the Q900/950 for best machine for A/UX.

I don't really remember. I'll look next time I'm in there (the Q800 case is not nice to disassemble :P ).

My daughter gave me her old iPhone (iPhone 6 I think.. it big anyway) a month back, she said, Father, I'm sick of seeing you with a plaster holding your phone together..

I dropped it a week later.. and the screen smashed FFS!! I can't show her, I'll end up on the Jeremy Kyle show.
