    Running the Thunder II 1360 at 1600x1200

    Ok will take a look.

    PowerBook 540c Restoration Project

    Some more notes after debugging. Looks like the Powerbook cuts the power (both +5V and +12V) to the hard drive when it spins down. Figured this out when I saw that the issue doesn't occur if I have a USB cable (for serial debugging) plugged into the ZuluSCSI (since that cable continues to power...

    Running the Thunder II 1360 at 1600x1200

    I see. Well looks like I have a non-GX Thunder II 1360 so mine would probably be different. Wish it had supported 1280x1024 out of the box since it can support 1360x1024. Oh well.

    PowerBook 540c Restoration Project

    Oh, and this reminds me, when I played with this last year, with a normal spinning disk installed, I did not get lock ups on spin down / spin up.

    PowerBook 540c Restoration Project

    So my lock up issue, been playing around some more with the "spin down hard disk" setting set to 1 minute. Once the drive spins down, accessing anything on disk that has not been recently accessed causes the "lock up". But it's not a permanent lock up. I wasn't patient enough before. I decided...

    Running the Thunder II 1360 at 1600x1200

    @eharmon did you ever figure this out? Curious if you were able to get the 1360 displaying at 1600x1200. I've got a slightly different need.. given the card supports 1360x1024, trying to figure out whether some tweaks can allow it to support 1280x1024? I've got a native 1280x1024 LCD which is why.

    MacsBug on Quadra, Heap Corruption

    Ok, well unless we're both using a set of faulty OS install images and/or have the exact same hardware issue across our machines, then this sounds like a common issue and benign. I'll stop worrying about it :) but I'm still curious why.

    MacsBug on Quadra, Heap Corruption

    I installed a vanilla/default installation of 7.6.1 onto my Q700 and also installed MacsBug 6.5.3 (same as yours). And now I get the same exact result as you on your Q700. There's a ! indicator but MacsBug 6.5.3 doesn't report heap corruption. If I use MacsBug 6.6.3, it does report the...

    MacsBug on Quadra, Heap Corruption

    Mine shows the same thing. But the MacsBug manual says that ! character in the "Master Pointer" column means: Which shows in both of ours for heap block #2 in heap zone #2, but mines complaining about heap corruption whereas yours is not. I am however running System 7.5.5 whereas you're...

    MacsBug on Quadra, Heap Corruption

    On your Q700, can you do a 'hx 21d0' followed by a 'hd' ?

    MacsBug on Quadra, Heap Corruption

    What you're seeing with your Q650 is what I'm seeing with my Q700, Q800, PB540c. Weird. BTW, my Q700 is also 68MB of memory, no cards, and ZuluSCSI. Are both of your machines running the exact same System version? That heap zone with the error is an embedded one within the system heap.

    PowerBook 540c Restoration Project

    Got bit by the drive spin down issue again. Realized when I changed OS's, I knocked out the power setting to never allow the hard drive to spin down. Disabled the spin down again and left it running for a while. No lock ups. If this holds after a while, I guess I'll try overclocking the CPU again.

    Seeking beta testers for Mac Sync-inator VGA sync converter

    @David Cook were you testing with an LCD monitor? I remember having a discussion about washed out colors with @bigmessowires. In my case it was because the sync signals were being sent on R, G, and B, by the video card causing the LCD to misinterpret the input range and rendering the colors at...

    MacsBug on Quadra, Heap Corruption

    BTW, my Quadra 700 has a ZuluSCSI and extra memory, but no cards or anything like that and no other changes from stock.

    MacsBug on Quadra, Heap Corruption

    Ok I see. If it's not too much trouble, on your Q700, what do you see for the first four heap zones when you run 'hz' in MacsBug? I'm seeing: Heap zones #1 32 2213K 00002000 to 0022B6AF SysZone #2 32 1K 000021D0 to 00002873 ! #3 32 9K 00077970 to 0007A163 #4 32 185K 001D2700...

    PowerBook 540c Restoration Project

    I'm going to leave the stock crystal in for now and see if the problem goes away. It only happens after being on for a while which is why I thought perhaps the overclocking was causing overheating. I had run MacBench tests when I first overclocked with no issues -- because I think @croissantking...

    Ah ok. Well, I can stop worrying about that then :) thanks for the confirmation.
