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.

Yes, I picked: OEM 000-48303 (October 1996) Workstation release. md5sum nt-4.0-ppc.iso # ab37556d72818ed082c1d01c2d7f1898 see https://github.com/pappadf/powermac-nt-hal/wiki/Emulator-Media-you-must-supply

Yes, long term that's a much better approach.

Yes to both; and yes, Microsoft did port the cirrus driver to ppc. It ships on the cd. SCSI: symc810.sys, ms' own miniport for the sym/ncr 53c8xx family, driving both 53c825a. Nothing new. Getting setup to choose it took one patch, though -the veneer reported the scsi identifier as NCR,53C810...

I agree complete - I've no intention to modify/patch anything more than necessary. There are 4 things that today needs to be added or patched: Adding a new HAL (*.DLL) file (separate file) Adding an ADB driver (separate file) Modifying \PPC\TXTSETUP.SIF to add a new installation option (the ANS...

Milestone: I have a desktop on emulated ANS. (Doesn't necessarily carry over to real hardware, all stuff in https://github.com/pappadf/powermac-nt-hal/tree/pappadf-experiments) My next idea is to build a small web application (local page js/wasm only, no server side): You load an iso image of...

I pushed new content to https://github.com/pappadf/powermac-nt-hal/wiki (as before, indeed based on AI tools).
