Windows NT bringup will be longer side discussion, and in order to not pollute this thread more than already done, I started a separate side thread about Windows NT specifically: https://tinkerdifferent.com/threads/windows-nt-4-0-on-the-apple-network-server-and-tnt-macs.5724/ Hope that everyone...

This is a breakout from the thread Apple Network Server MacOS based ROMs found. Triggered by the ROM findings, bringup of Windows NT becomes a larger project and quickly takes over the original thread. To not pollute the original thread more than already done, I thought it might be better to...

I also have a parallel project half way up and running: It boots, but it is with a lot of "artificial" help. I'm working on some better patches, but OS/2 is more of a mess, as it lacks the HAL of NT.

Excellent work - running the entire install phase on real hw is a great step forward! (Much bigger achievement than running in emulator) I will study your findings! On a related note, I updated the boot floppy build (powermac-nt-hal) to not include any Microsoft code at all, i.e. everything on...

Emulation of the Apple QD3D Accelerator "Gotham" Just a very slow prototype at this point

Emulated G3 (wasm JIT) + Rage 128 (WebGPU backend) playing Quake 3 in the browser:

Just tagged version 10.0.x - adding a couple of new CPU models: Two "Pre-decoded" models for 68K and PPC respectively, and one Wasm JIT for PPC. Still early stage, so I really need to tune performance, but I had to start somewhere. Small example here: You can try it out here...

Hi! First a disclaimer: this is a first prototype, only tested in emulator, so one should expect bugs. That said, yes, communication happens over Lisa's serial port B. However, it's not a ordinary serial port (i.e. not RS-232), but the Lisa hardware will in this case rather run synchronous...

A first prototype of "LisaShare" - AppleTalk Stack and AFP Client for the Lisa Office System Try it out here: https://pappadf.github.io/lisa-share/ ...and code here: https://github.com/pappadf/lisa-share AI tools has been used here as well, and I also had the advantage of having another...

Indeed - and it would solve a number of practical problems (e.g. how to easily move fils in and out of an emulated or real Lisa). From a hardware perspective, I think it should be all good, i.e. as far as I know, you could use AppleTalk under MacWorks - it's just the software side that is...

(previously posted this on 68kmla): I wanted a way to write Lisa applications in C, so I put together a small cross-development environment based on the Retro68 compiler. If you're interested in developing Lisa applications in C, you can check it out here: https://github.com/pappadf/lisa-c I...

I have now made some improvement re. ROM handling (I just tagged a new version of my small project). I have not fully bypassed post (as discussed above), but I have tried to bypass the scsi probe delay (not always successful though). Available for anyone who what's to play with it...

(also shared on 68kmla) I wanted a "virtual" LaserWriter for my small emulator project, and it all got out of hand, growing in scope to the point that it became a project on its own. For anyone interested (that needs to simulate a LaserWriter or convert PS to PDF in general), you can try it out...

Terrific! This is on real hardware right? Very impressive! Getting it running on hardware is always a much bigger challenge than in an emulator. I as mentioned, I have transformed my emulator experiments (https://github.com/pappadf/powermac-nt-hal/tree/pappadf-experiments) to work with a...

Sounds excellent! This is on real hardware, right? I've reworked my experimental branch to use the floppy + unmodified CD approach as well (I've pushed all updates to that branch). It almost works fully in the emulator.
