    Help getting started with retro software development

    You shouldn’t need to initialize the array in order to “reserve” it - it should be allocated for your application when your application loads (since it’s defined as a fixed array in your source - dynamic memory allocation is another subject). I’m suggesting initializing the arrays with a known...

    Also - the mapTile array is updated in a few places based on the content of the entity array, so if the entity array is uninitialized or corrupted, it could corrupt the mapTile array.

    Help getting started with retro software development

    A couple of times on my Duo running 7.1 I was able to reproduce the blank map bug that you saw under 7.5.5, but I didn’t see the “stop sign” bug that you saw under 7.1. Most of the time it ran fine, both the compiled binary you provided and when I rebuilt it with THINK C 5. I’m not sure that’s...

    Thanks for sharing! There’s nothing to be embarrassed about - you were/are learning, and I’d venture that most of us here (myself included) have done no (or very little) Classic Mac programming. That said, there are some experienced folks here that I’m sure would be happy to take a look.

    I’m sure some folks here would be happy to look at your code if you could post it somewhere, or attach the whole project here as a StuffIt file (SIT)

    Tantalum after ReCap catches fire — why?

    You’ve found the main drawback of tantalums - when they fail, they fail catastrophically - blowing up, and often shorting their terminals. The main causes are reversing their polarity (installing them backward) and exceeding their voltage limit (which is why they are so excessively de-rated...

    IIfx - Spectre won't run on main monitor

    It’s been a long time, but my recollection is that you can hold option in the Monitors control panel, and a little Mac icon will show up on one of the displays, which you can drag to the other display (just like you can with the Menu bar). I think that sets the default/boot monitor, which may be...

    I want to load OS9 on an Apple iMac G4 800 17" (PowerMac4,5) what disk version came with it?

    Can you provide the model number? There were a few different iMac G4s, and they probably came with different install disks.

    mac 512k won't boot from floppy

    When you boot from the Emu, you say that it reads the malfunctioning floppies fine. Have you tried copying anything to/from the malfunctioning disks when you’re booted from the Emu, or do you just mean that the disk shows up and you can open it and see the contents? Has the drive been serviced...

    Quadra 630 does not support 24-bit memory addressing mode

    Ah, fair enough. Awesome detective work, sorry your IIe card won’t work as a result!

    Quadra 630 does not support 24-bit memory addressing mode

    Apple agrees with you, only 32 bit is supported: https://support.apple.com/kb/SP229?locale=en_US As an example, here’s the page for the Quadra 650, which does support both modes: https://support.apple.com/kb/SP232?locale=en_US

    Dumb PowerPC question

    I’d (mostly) second that recommendation. Find an ISO of one of the retail OS 9 releases (I found 9.0.4 pretty easily, I think there’s a 9.1 or 9.2 out there as well). I’d avoid the 9.2.2 “universal” installers that are out there - as far as I know, Apple never released a 9.2.2 retail CD, mostly...

    Can Color Classic I & II boot from SCSI CD-ROM?

    How did you burn the CD? And what image did you use? It’s possible it wasn’t burned in a way that is bootable.

    Can Color Classic I & II boot from SCSI CD-ROM?

    It doesn’t matter what ID the devices have, as long as none of them conflict (remembering that the Mac is ID 7). It’s pretty typical for Macs to use 0 for the internal HD and 3 for a CD-ROM (either internal or external), though that’s just convention.

    PowerBook 520 can't boot 7.1.1

    It could be worth zapping the PRAM if you haven’t already. press apple-option-p-r right after pressing the power button and hold it down until the machine reboots a couple of times (multiple chimes).

    AirPort Card hung up, case won''t open! Any suggestions? DA & QS'02, same memory type?

    EveryMac says they both use 3.3V, PC133 SDRAM (168 pin) https://everymac.com/systems/apple/powermac_g4/specs/powermac_g4_733.html https://everymac.com/systems/apple/powermac_g4/specs/powermac_g4_800_qs.html
