It's a bit stalled, most of my projects get stalled for a while and then resume. Yeah, the MOD player! Well, it's a good question, because although things like MOVE reg,reg aren't much faster on MØBius (Shift+Option+O); MOVE reg,disp8(An, Am|Dm) are very much faster. MOVEP is also much faster...

Thanks! The main reason I'm sure MØBius will work with MIDI is that it dedicates a whole core to continually running the CPU, so it's never timesliced. The second core is for background processing for peripherals and hardware. My intention for Serial data is to map SCC configurations directly to...

I still plan to make it more usable, but I haven't been working on it for a couple of weeks. It almost plays properly with my current version (which loads .mod files; allocates space + workspace and runs the preparation code from 'C' versions).

MIDI will work on my MØBius RP2040/RP2350 based emulator. https://68kmla.org/bb/index.php?threads/more-pico-mac-stuff.48673/page-2#post-564986 @MIST : I thought there was a difference. On a real Mac, you need an external clock signal (Hsk?) at 1MHz or 0.5MHz and the SCC configured to let HSk...

Good point, I hadn't checked. In fact it was in 32-bit mode, but switching to 24-bit mode was the same: 2495kB to 2506kB.

I'd run System 7.5 on any 68030 Mac faster than 16MHz, so a IIsi or up! Meanwhile, System 7.5 can be squeezed into 3900kB on a PowerMac 6100 in 1bpp mode. Or down to 2500kB on a Q650, both via Infinite Mac. Gosh, PPC is hungry!

Good point. Haven't checked that, but this one supports 801.11g. Does that make it Airport Extreme?

Indeed. Knowing some eMacs were designed to boot natively is a real help or knowing others certainly won't at least makes things clear. It's the Twilight Zone of the 1GHz ATI eMacs that causes most of the hassle as one has to spend far more effort working out which side they fall on. Up until...

And in the end it was pretty much that simple. I downloaded the Unsupported Mac OS 9.2.2 CD from Macintosh Garden. https://macintoshgarden.org/apps/mac-os-922-install-unsupported-g4s I restarted with the CD in and pressed Option. The CD appeared to be bootable, so I clicked it and hit Enter...

Thanks, I'm aware that I could create an alias, it's just that I seem to muck up the syntax and end up just copying the whole path. Lots of useful info, which I'll try and reply to later when I have time. I realise from the above that the Mac OS 9 System Folder wasn't blessed, because I...

OK, so a bit further on I'm reading about OS9 ROM Fixer and ataboot.py, but also OS9 ROM Fixer doesn't work on Tiger. Do I even need this? OK, so reading another topic, I think it doesn't allow you to format for OS 9 drivers, because the Mac already thinks that OS 9 isn't properly supported...

I wondered if it didn't get further than the Happy Mac, because there wasn't a PPC disk driver. But in reality, there appears to be 4 68000 drivers, but no PPC disk drivers on the partition map (it's an Apple Partition Map drive, which I think it needs to be for Mac OS 9). Read...

OK. I found a MAC OS ROM: https://macintoshgarden.org/apps/mac-os-9-roms-without-15-gb-limit I can now manually try to boot from OF with: 0 > boot /pci@f2000000/mac-io@17/ata-4@1f000/disk:,\System%20Folder\MAC%20OS%20ROM I don't know what the CDG5 code is, unless it's a French reference to...

I think that's what I'll try next. I think I need a Mac OS 9 Lives account to do that. On this page: https://macos9lives.com/smforum/index.php?topic=5773.0 "Yes, makes sense, as Gary stated your hardware is almost 100% good for a native boot, al you needed was the "imic" ROM injection and...

OK, so it turns out that my eMac is a M8950/LLA which according to all available sources can boot directly into Mac OS 9.2.2, if I have the installation CD for that kind of model ( eMac ATI, ideally eMac ATI 1GHz). I don't yet know how to use OF to trick the CPU speed if that would be an issue...

Hi folks, I finally have a potential buyer for my eMac (originally from @CircuitBored ), who wants to use Pro Tools 5.1.1 with it, which needs the Mac to boot properly into Mac OS 9.2.2. This eMac should be able to do that. It's really an ATI 1GHz Combo (still a Combo) and this EveryMac page...

An 8MHz 80286 is fast enough to support at least 6 MOD channels with a Mac Plus and earlier audio (which is also PWM), see my earlier listing. PC/AT class machines had DMA, so I suppose one could could hook up a timer at 22kHz to trigger an 8-bit DMA transfer to another timer reg controlling a...

Indeed, it demonstrates low-bandwidth is a terrible problem for all concerned. viva Net Zero :) !

I spent a bit of time on it today. I think I've basically debugged my 'C' version of the Init and Perform: assembly code, in a standard 'C' test harness. It still crashes on the actual app. I think the next step is to get better debugging on miniVMac to work. Not sure how.

Every-so-often I keep searching for this post as it seems like a simpler way to rebuild a PowerBook 1400 battery, but most of the search terms I use keep missing. So here I'll just list my likely search terms: "Rebuild PowerBook 1400 Battery" "Rebuild PowerBook 1400 Battery NiMh" "Rebuild...
