    I own this powerpc 7200/90 and it always has a loud sweaking sound that come every now and then. It seems like its the motherboard not the fan.

    It runs on os 9 and is super slow and there is barely anything installed on it. How should this be fixed?

    Also it doesn't seem to read dos/ibm floppies. Is there a way to fix this? (i'm scared it can't read mac floppies but i don't know)

    Re the speed issue, this is a 90MHz PowerPC 601 - one of the earlier PowerPC chips from 1995/96, so it will definitely struggle with OS 9 (having shipped with System 7.5.2).

    I remember because I also had one of these and tried the same thing!

    OS 9 was rarely lightning fast on anything pre-G3 to be honest.

    The only thing I can think of doing for this old machine is maxing out the ram
    to 512mb using 4 128mb sticks of ram
    then try it on 9.1 and it should be just fine

    a larger harddrive will also help but not with speed

    I had one back in the day. I bought Mac OS 8.5. I found 8.5 struggled on it. I couldn't upgrade to 8.6 as it required 24MB of physical RAM. A few months later I got a blueberry iMac DV 400

    Have you tried Mac OS 8.1 on it?

    Faster

    Ram and os 8.1 are both great ideas for the machine. If you don't wanna change anything else I would say a cheap pci video card will speed it up as I just did that for a friend. Best upgrade path though to keep the case is a 7300 or up motherboard as it slaps right in and processor upgrades are cheap up to g4 on eBay.

    Good luck

    For the squeaking: You might want to consider changing the capacitors on the motherboard and/or power supply.

    I had an old Fujitsu FM Towns PC that made a high-decibel noise while powered on, and one of the capacitors in the power supply had failed.
