Anyone use Snow for SE/30 emulation?

[rplacd]

I think the other forums (e.g. TinkerDifferent) talk a lot about Snow – anyone else have any experiences?

If you haven't heard of it, it's a faithful hardware-level emulation of early compact Macs – incl. emulated SCSI devices like a DaynaPort Ethernet adaptor + a BlueSCSI. You can simulate a lot of SE/30 hot-rodding.
Currently, I have run A/UX (separate thread... sorry if I seemed over-excited). If you want, since both Qemu and Snow use raw HD images, you can set up things on Qemu, and transfer to Snow's emulated SE/30.

But, has anyone done this? I think you can also simulate the steps needed to run MacOS 8: using a custom 32-bit clean ROM (e.g. IIsi), going through all of the annoying hoops to patch...

I played with Snow back when it was originally released, but I hadn't seen quite how much development had gone into it since. Looks like it's getting quite complete now.

My old disk images work just fine in the latest version too, which is always a good sign

I had a little play with a pre-patched 8.1 for an 030 (the BlueSCSI prebuilt images share has a raw image) with the SE/30 machine type and a IIsi ROM, but it doesn't get past the happy mac (I waited a while with it set to "fast forward"). I do notice that your screenshots in the A/UX thread are a later build than the current 1.4.1 f1be857 on the github page - I see that there have been lots of fixes since then so maybe it's worth building from source and trying again.

Yes, today's Snow build (1.4.1 756dbc1) has fixes that allow it to boot A/UX 1.1 and 1.1.1. Of course, if you're going to run A/UX at all, you probably want to use 3.1.1 rather than the early versions, but this is still a great validation of the hardware emulation.

(Sorry, this is a Mac II rather than SE/30 screenshot and maybe belongs in the other thread. )

I fiddled around with it a while back... wasn't a fan of the UI. At all. Most annoyingly, there was no obvious way to make the video not scaled.
Perhaps it's time I gave it another whirl...

This is great news for me... I like to emulate ALL the systems! Snow will likely be a better workflow than Shoebill.

Sorry if this is a stupid question, how can I download the ROM image of my machine (SE30 and LC475) please ?
Or can I find the somewhere ?

Search the Web for "macintosh (SE30/LC475) rom"

Last I checked you can disable scaling

Hi

I already did, but doesn't accept it for the SE/30.



If I use the SE ROM file it accept it and works well.
