    Q840av gets a make over

    You said that in a southern U.S. accent. :D

    Developping a new After Dark 3 screen saver, the "Screen Shaver" based on Japhy's idea and art

    That's cute! I like how you uploaded a really short video to demonstrate. Everybody else tends to stretch things out to 20 minutes. You should make the shaver miss spots once in a while and need to go back at the end.

    Q840av gets a make over

    Ahh! The simplest solutions are the best. Cool build.

    Q840av gets a make over

    This is very interesting. A IIci case? What tool did you use to remove open up the back ports? Does the Quadra 840AV identify itself correctly? Despite not having the little loop of wire on the LED connector to indicate that it is in a tower case?

    Metrowerks CodeWarrior Best Version and Updates

    1. In Pro 4, I was unable to compiling PPC code in Basilisk II. It crashes. It compiles 68K code just fine. CW 11 compiles both PPC and 68K code in Basilisk II. 2. In Pro 4, they have switched to the new Mac OS constant and trap names. In CW 11, you can use either. I don't know what I am losing...

    Wombat (650, 800) board overclocking limitations

    Ha. That's an unusual situation. "Crash never" and "crash always" I understand. I wonder what it is changing (globally?) that causes the second launch to work. Do you think it is unhappy with the ROM disk?

    Metrowerks CodeWarrior Best Version and Updates

    CodeWarrior 11. I created Tiny Transfer in that environment, and successfully tested it from System 1.0 (aka 0.97) to 9.2.2 (the final system) on all Mac processors from 68000 to PowerPC. That being said, Tiny Transfer is not a fat binary. So, I have not confirmed the quality of the PowerPC...

    Anyone have an SE speaker?

    Same here. What causes them to go open?

    Macintosh IIfx ROM Modifications

    How difficult is it to substitute bytes in unused areas to make the checksum match? May need a math major for this. I was thinking about using the same bit in PRAM as later machines to disable memory check at startup. Maybe hack the Memory control panel to always show that option?

    Introducing ZuluSCSI Blaster - now with More Cowbell!

    Thought it would be worth posting Blaster performance on the Quadra 605 (w/Bolle 128KB cache and 40 MHz overclock). Reached 4.5 MB/sec!

    Introducing ZuluSCSI Blaster - now with More Cowbell!

    Both the ZuluSCSI v1.1 and Blaster were connected externally with the ProDrive internally. Yes, ZuluSCSI works from external term power ("Designed to be powered via SCSI termination power when provided by the host"). When I pulled the ProDrive, I added in an internal terminator that includes a...

    Introducing ZuluSCSI Blaster - now with More Cowbell!

    Back on the topic of this thread. I encountered something a little weird. On a completely recapped IIsi, with the Blaster attached externally and an internal Quantum ProDrive, the SCSI doesn't work. The ProDrive won't even spin up. * If you plug a power cord into the Blaster, then everything...

    Introducing ZuluSCSI Blaster - now with More Cowbell!

    I am considering hacking that code back in to see what happens.

    Possible to get the saved instruction address at interrupt time, in a Time Manager task?

    I just looked at your code. You are a good programmer.

    Is this a Sync on Green Issue? MacIIsi with an AD-A205 adapter

    I believe this will take care of your problem: https://www.bigmessowires.com/2024/04/15/mac-sync-inator-vga-sync-converter-launches-today/

    Possible to get the saved instruction address at interrupt time, in a Time Manager task?

    Congratulations! That was a lot of hard work. Good to hear you were successful.

    Introducing ZuluSCSI Blaster - now with More Cowbell!

    Very interesting. Given the faster-clocked CPU, the non-DMA mode must really stink. Apple patched it out in the leaked source. Not sure if it was ever renabled. ; <57> 04-22-90 csd ; commented out the installation of SCSI DMA so we stop trashing ; hard disks on the IIfx. movea.l...

    SE/30 Power Supply: Recap or ATX?

    @s_pupp Thank you. I'll have to try that. @shirsch I had no idea these existed. They are some knock-offs on eBay that aren't very expensive at all.

    Possible to get the saved instruction address at interrupt time, in a Time Manager task?

    It occurs to me that some of this gloabl stuff may not work during interrupt time. And, you might need to be in the correct help to call GetResInfo. Best to start with an application-only profiler and then work up to some crazy stuff.

    Possible to get the saved instruction address at interrupt time, in a Time Manager task?

    I guess it depends on whether you are trying to make a global profiler or only for the application that includes it as a library. If it is only for the current application, then you can call CountResources and GetIndResources to make sure all 'CODE' resources are loaded (hmm... maybe you need...
