Hi Apache Thunder, nice machine. If you want to go for a SE/30 (which I highly recommend) just take your time. The prices over here (Old Europe ;D are often insane (especially on eBay) and I guess even higher than in the US. But if you take your time you will find reasonable prices for good...

C13 has nothing to do with sound IMHO. You can find SE/30 schematics on the web. C13 is part of the pullup/pulldown of the power connector J12. It should connect to pin 12 of J12.

Why not use Mac OS 8.6?

Are the 4MB SIMMs so called "composite SIMMs", i.e. they are constructed of a lot of smaller memory chips and some logic? This might cause problems.

I'll try 8.1 when I find the time. In the meantime I got a 256k cache card which helps. Thanks four your advice.

I found some programs and provided the links above. Will have as look at the Garden though.

I ordered a replacement cap. Will feed back after I installed it.

Yea, please, do so.

Don't have much to add to what was said before. If you want me to speculate: the HDD (it was added afterwards, right?) might draw a bit too much power for the PSU of the SE. Do you know which type it is? But then it worked in this configuration for quite some time I guess.

Super Mandelzoom is black and white and also runs on PPC. You can see the difference in performance. Floating Fractals runs on both architectures and shows the difference, too. I think just for a quick demo PowerXplorer (http://archives.math.utk.edu/software/mac/fractals/PowerXplorer/) is the...

I solved it in another way: made universal OS 9.1 Jaz on another Mac, booted the 6100 from that, copied system to the internal HD. So I had a universal OS 9.1 (with extensions etc. with all kinds of Macs) but it was very slow. I then found another CD-ROM drive (also non-Apple). This one would...

Hi, I acquired a Quadra 650 which was in very good visual condition but would not start up. I'll make the long story short: the Quadra has a blown capacitor C203 on the underside of its mainboard: (the cap was initially "complete" but blown - one part fell of when I tried to clean the...

That would not work because you have to boot from the Mac OS 9.1 install CD if the installed Mac OS version is < 8.5. If you still try you get an error message saying that the system cannot run the installer. BTW, I was wrong with my second sentence. The 6100 does not even see the...

Hi, I'm struggling to install Mac OS 9.1 on my 6100. The only CD-ROm drive I have is a third party one and I cannot make it boot from the original Mac OS 9.1 install CD. I also cannot install OS 9.1 from the mounted CD without booting from it because the 6100 currently has OS 7.5 installed...

That does not sound good. I just have the usual stuff to offer: did you zap the PRAM? Is the PRAM battery good? In the Service Manual for the 840 AV there is a procedure to reset the logic board (http://tim.id.au/laptops/apple/legacy/quadra_840av.pdf). 1. Unplug power cable 2. Remove PRAm...

Thanks Elfen. I did some more research last night: There is Super / Color and Power Mandelzoom by Robert Munafo (e.g. http://mrob.com/pub/muency/supermandelzoom.html) And Adam Smith's Floating Fractals 5.1 (e.g. http://archives.math.utk.edu/software/mac/fractals/FloatingFractals/)

Hi, is there a fractal image generator for mandelbrot's etc. that runs optimized on both 68k and PPC Macs? I'd like to do a tangible demo of the advances in computing power between 68k (Mac SE/30) and  PowerPC (PMac 6100 or G3). Maybe there are other programs that are well suited for such a...

I tried CPU Director 1.5f5 and that works! :beige:  I can now control the 2nd level cache amongst other things. BTW, the ZIF processor card is a Metabox joeCARD Z 400 Mhz. I think it was a unauthorized clone of a US product by a German company and that was also the reason why they had to cease...

My 100 MB USB Zip works perfectly well here on a recent iMac. It has model number Z100USBS and is from 2002. SCSI Zips work on the SE/30. But you still have the HFS / HFS+ issue. I use a middle age Mac as an intermediary. Or you could fall back to DOS/FAT (what a shame...) but lose all Mac meta...

I tried CPU Director 2.3b4 and b6 but it would not run on my beige G3 mini tower. It seems to be for OS 9 and OS X (has respective folders with resources and the readme says so) and I installed the system init it produces an error message relating to OS X (ioctl...) on OS 9.
