Install MkLinux > compile QEMU ppc (KVM?) > launch with a Tiger image > wait a few days for it to boot and you have OS X on a 601 nubus PowerPC :)

someone actually did that with pearPC and a 68K Quadra IIRC, they calculated that it would take something like a week to boot to an OS X Desktop. :D

Ok, it's not a PPC... But note it browses the PPC forum.

PowerBook G3 PDQ "Limited Edition" with 512 KB L2 cache and 12.1" active matrix display. This was brutally slow.

I dont speak german but is that 32MB of RAM?!

very nice find iv read about this model of PDQ but never seen one.

not used one personally my self but there was the Mainstreet 12.1 inch passive matrix LCD and a 233Mhz G3 with No L2 cache apparently its very slow but much more common then the 12 inch PDQ. iv always wanted to see one/get one to see what OS X is like on a passive matrix LCD tho :)

Yes, that was a test to see if Jaguar would boot with just 32 MB of RAM. I've upgraded to 192 MB now. :) (Sadly I don't have any 256 MB modules with 16 chips).

I was initially only aware of the Mainstreet with its passive matrix LCD and lack of L2 cache and was therefore skeptical about this one, but the presence of cache got me thinking. And the display is definitely an active matrix.

As far as performance is concerned, boot time (with 192 MB RAM) is about 105 seconds from the grey Apple logo to the desktop, using the original 2 GB IBM hard drive. I didn't measure boot time with 32 MB RAM, but I'd estimate it was at least five minutes...

Wowzers. Here I thought I was cool with my factory iBook g3 clamshell. Don't upgrade that machine! Be sure to keep all of it's original working, and keep original CDs and manuals!

I have a PDQ with a 12.1" display, too, so possibly also one of these. Thought it was a Mainstreet but it had the PDQ livery on the base, so I then thought it was a cut-and-shut until Everymac put me right. But 32MB of RAM is a cruel and unusual punishment to wreak upon OSX. Poor Jaguar :eek:

I have a passive matrix Mainstreet but the screen was cracked so I replaced it with a 14" display from a donor PDQ. The one screen I have never seen is the supposedly unreliable 13".

Wow I didn't even know OS X could boot with that small amount of memory :)

I thought 64MB was the limit for Pre 10.3 OS Xs (I do know from personal testing the limit for 10.4-10.5.8 is 91MB)

I do know OS X Server 1.2v3 works with 32MB of RAM (iv installed it on my PowerBook 3400c which only has 32MB)

does 10.2.8 still boot with 32MB of RAM?
 
My Mac Quicksliver has 512MB of RAM and it's running OS X 10.1 which I flip back to OS9 ;) I think its close to the max
 
It occurred to me I have 10.1.5 installed in Mac-on-Mac so I set out to determine the bare minimum in terms of RAM; turns out my PDQ was quite close to it:

1f659570eb72f78d804865553edf4e9f.png


(Sorry again for the German screenshot) 30 MB... 29 or less and it fails to boot.

What host system used for Mac-on-Mac ?
 
Sadly I don't have any 256 MB modules with 16 chips.

There was a Chinese seller on eBay that had loads of these for around $2 each. I bought eight of them and they all worked fine in my two Wallstreets and my Bondi iMac. I don't know if he still has them, but it's worth a search. Unfortunately, I don't remember the seller's name.
 
Latest two acquisitions: First, a beige G3 desktop.

Beige.jpg

Second, a Workgroup Server 9650

9650.jpg

The Server has a Daystar XLR8 Machspeed G3 upgrade card installed. This is the later slocket type with a small heatsink and 12 dipswitches to change multipliers and CPU speed. There is potential for getting this to run on a Yikes G4 cpu if I can find one.

Both the floppy and the CD drive seem to be faulty but I have a dead 8600 I can graverob for replacements. This came with an Apple CRT monitor but I have already replaced the iXMicro Twin Turbo card for a Rage 128 until I can find something a bit better. The monitor was surprisingly light for a CRT.
 
ohh you lucky :)

I saw that 9650 on ebay (the seller posted about it here before the mods nuked the post) Sadly the seller was offering just collection only, glad to see you managed to grab it tho :)

(iv been looking for a 9600/9650 for yonks same as the 6500...)

I own a slightly later version of that slocket (mine makes no mention of G3s and has a 1999 copy right date) but no machine to put it in LOL was a cheap win on ebay a few years ago, i got it since it had a G4 ZIF in it which went into my G3 beige at the time to test my Custom Leopard image I made for Running Leopard on Pre Uninorth machines :)

if you need a dip switch chart I have one somewhere. :)

BTW I noticed it says 2MB of Total L2? whats in that drop down menu there? quite curious. iv not seen that before

also I see the G3 Beige DT has a 300Mhz CPU being the 1MB L2 variant im guessing this is its stock CPU? can you grab a picture of the die? im really curious if the G3 beiges faster then 266, used the MPC750A or the XPC750P CPU...

Any cache will be from the XLR8 card. This is the later 9600 LoBo with no onboard cache chips. Profiler says 2MB external cache, no backside cache. XLR8 control panel says 1MB backside cache, as expected. I think this might be MacOS 8.5 not handling XLR8 properly. I believe MacOS9 or later was recommended by Daystar although I haven't looked too deeply into that yet.

I found a 1997 CD from Daystar on archive.org with all the relevant files and the seller helpfully left the same on one of the hard drives. Those are both running on a Jackhammer card already. Sadly, the seller mislaid the 604e card, which I really wanted as it was the hard to find 350MHz version but I have a 300MHz in my dead 8600. No idea if that works or might fry my 9650, so a little nervous. I might try the Daystar in the 8600 first.

I haven't peeked at the CPU on the beige G3 but I might repaste in the near future so will check then.

There is another 9650 going in Germany right now with local postage only. You could use Mailboxde.com to ship it to the UK but I think costs are going to mount. You might not see much change from £150.
 
thats what I was thinking, the G3 750 (MPC/XPC750 and PPC750L) only support up to 1MB of L2 backside cache.

as for the 300Mhz card, assuming the CPU aint the reason the 8600 is dead it should work fine in your 9650 :)


I know of a 9600 in Sweden, but shipping as you say is what kills it for me, if you do get a G4 for the 9650 I have a Leopard image that should boot on it let me know if you want to try that out :)

I considered the Swedish one, especially as the price has dropped to £50 but it only has a 200MHz CPU. The total cost is now commensurate with the going rate in the UK for a working 9600. I suppose I was very lucky, especially as I had donor parts ready.

Just finished swapping the floppy and Zip drive over from my 8600 and all work now. Checked the CPU and the 8600 has only a 250MHz card. Better than nothing.

Looking at the Freescale datasheets, the MPC750A topped out at 266MHz, whilst the XPC750P started from 300MHz. Looks like it could only be the latter unless Apple was into overclocking

while I dont think Apple ever overclocked anything (in fact all of the 867Mhz MDD CPU cards I have seen have 933Mhz rated chips LOL)

I have noticed that apple have had custom parts spun for them, like a lot of the Later PowerPC Chips (74xx ones) will have a different Part-number and their own little datasheet detailing whats diffrent about it from the main datasheet. like the 533Mhz 7410 Apple used in the DA is rated for 2V (tho Apple ran them at 1.95V if the VID resistors on the CPU card is anything to go by) rather then the 1.8V a regular 7410 is rated at :) (you could view it as official overclocking :D especially these 533Mhz 7410s where only rated for a max die-junction temperature of 65c as well, vs 105c of a normal MPC7410 it could also be since these 7410s where meant for a regular computer setup rather then some Mars rover embedded type setup :D)

https://www.nxp.com/docs/en/data-sheet/MPC7410PDPNS.pdf?fsrch=1&sr=1&pageNum=1 "custom" Apple 7410 data sheet

https://www.nxp.com/docs/en/data-sheet/MPC7410EC.pdf and the main regular 7410 datasheet.

so im curious if Apple had a custom spec/speed MPC750A spun or used an XPC750P. (I also have the same question for the 292/300Mhz WS/PDQs if they use XPC750Ps then it should be very easy to slap a G4 7400 onto/into one :) )

I have a 500MHz G4 upgrade card for a Wallstreet that I have never got to work. If I can find it I could look at that to see what chip was used.
