Doesn't infinite Mac take the C/C++ emulators and compile to WebAssembly (@joevt , @mihai )? If so, the host is still 64-bit. But it could be a big-endian/little-endian thing (e.g. a G5 PowerMac running Basilisk II under Mac OS X would be OK).

Firstly, 12345 will be represented exactly in every FP format, it's 0.11000000111001₂ *2^14 (the highlighted part here: 0.1100000011100100 is what the "40E4" is in the hex representation, because the MSB is left off). And, interestingly, 12345/0.000021 is approximately 2^29, though not quite...

I have a PB1400c & MBA M2. I've found the PB1400<->PCMCIA/CF<->CF\USB<->MBA M2. Having said that, it's not the only way. I've transferred data via Zip drives; and also via an IDE<->USB interface (unplug the PB1400's HD and plug into an external USB/IDE drive. Of course, you can't do that many...

Incredible! Well done!

@CC_333 : fine to be pedantic! My main point is that CW5 (or AW5) are pretty decent, but AW6, I thought wasn't that good. The important thing is that it's a good demo for a Classic Mac app that's not MS Office or MS Works. It's worth pointing out that those MS apps were widely used in the Mac...

Clarisworks 5 and World Book or Grolier World Encyclopaedia are probably the closest. MS Paint was actually modelled on the original MacPaint from 1984, but that won't run on Colour Macs. CW5, though is probably the most Mac-like integrated office package you could find. The next version...

Respect! And you have an iMac Flower Power. Respect! Happy xmas back!

I’m currently playing around with MAME’s realtime SparcStation 1 emulator (20MHz CPU). It reminds me how weird, powerful, ugly & slow GUI RISC Unix workstations were in the late 1980s to early 1990s. A world away from Macs, which are recognisably the same kind of platform, despite the massive...

Indeed, the technique with QEMU's SS-5 emulator is to use NFS. However, when I boot up the SS-1 under MAME, its MAC address in the emulated PROM is just FF:FF:FF:FF:FF:FF. And it doesn't boot automatically into disk3 (where the OS is), I have to type b disk3 each time at the OpenFirmware...

Aaah, anyway I've figured out part of the problem. I can get data onto the SS1 by creating a folder with the data I want, then creating an .iso image from macOS using: hdiutil makehybrid -iso -joliet -o image.iso /path/to/source Then I can boot into the SS1; log in as me; then su ; mount -rt...

Yes it could have been summer. The PERQ already seemed like an old design even in the mid-80s. Something tells me that SparcStation emulation on the 68KMLA on a thread about the Lisa might not be 100% on topic 🤣 ! But thanks for replying!

Good theory. I've never used a PERQ, though I think I saw one when I was visiting Unis during my 'A' levels (it was switched off). I also saw a Sun Workstation in 1986 with its massive monitor when I snuck off from the guided tour for about 15 seconds into a small office (I saw the computer as...

Puzzling, but normal. It's like a huge proportion of Stack Overflow topics where someone asks what seems to be a reasonable question (probably a similar one to the one I'm asking, which is why it came up) and all the answers are of the form: "I wouldn't start here", "you shouldn't be doing...

Cool, I've watched this now! I think most of what I knew about the Lisa came from the extensive benchtest in Personal Computer World (UK) in July 1983; the book "Insanely Great"; possibly bits from the biography "Jobs" and reading Folklore.org. It's good to describe the Lisa as an inflection...

Hmm. The way this thread is going feels a bit like you've got a massive, exciting vision and the response is more lukewarm than you kinda expected. I suspect this is partly or mostly because although you've thought a lot about it (and already put a lot of effort in), it only partially overlaps...

I did something similar with my Mac mini G4. Both of these Macs can boot from an external USB drive. So, my approach would be to use an SSD to USB ATA adapter (eg mSATA to ATA then ATA to USB, for example a 2.5” ATA to USB drive enclosure). Boot the iMac from your Panther CD and install...

My PowerBook 1400c/166 boots off HFS+ under Mac OS 8.1. Having said that, I got there in a convoluted way on my SD card. I started with Mac OS 7.5.3 on a 750MB HD. Then cloned it to an 8GB microSD (with an adapter); then I added another 5 x 750MB, HFS partitions. I had a retail copy of Mac OS...

Oh, OK. I'm sure I've seen one page or blog post measuring QEMU for various CPU emulations at about 1:30 to 1:60 native instructions per emulated instruction. That sounds about right for an interpreter. 1:50 wouldn't be fast enough for emulating SPARC on Raspberry PI <3, but even a simple JIT...

So are we saying that Solaris was the benchmark for Unix vendor workstation OS’s, better than Irix (which I think is a pretty good name), NeXTStep and that Alpha’s were pretty dodgy? (I have zero opinion either way, im Just having fun with SunOS 4.1.3 on a QEMU emulator. Though… @Arbee , is...
