I got myself a vMac emulator for 68k and am looking for good ROM for it and maybe some recommendations as to the best OpSys version to run on it.

Now don't automate me with System 7, as I am looking for the release with the best performance in vMac 68k, not the one best suited to this website's moniker. :D

I'm assuming by "vMac" you are referring to Mini vMac.

vMac was an earlier open source Mac Plus emulator project which development ended around 1999-2000 thereabouts (abandoned), although the web site for the original vMac still exists.

The spin-off, Mini vMac by Paul C Pratt, became the main center of development for this emulator.

The standard Mini vMac emulates a Mac Plus. This requires a Mac Plus ROM. There is no other ROM you can use with it. There are also variation builds of Mini vMac and those require different Mac ROMs

The Mac Garden has a collection of good working ROMs including the Mac Plus ROM. It will be included in the top #1 download on that page. The archive contains most of the known classic Mac ROMs. There are likely other locations for downloading just the ROM, but that MG archive is good for reliable working ROMs.

If you are using one of the Mini vMac variation builds that are available, then you will need the ROM for that particular build. e.g.; for a Mac 512Ke you would need a 512Ke ROM, for a Mac SE you would need a Mac SE ROM, etc. The MG's ROM archive will cater for any variation build, too. It's also good for ROMs suited to Basilisk II, SheepShaver, etc.

Best Mac OS? - well that's subjective. A Mac Plus can run any Mac OS from System 1.1 to 7.5.5.

My recommendation is System 6.0.7, 6.0.8, 7.0.1, 7.1 or 7.1.1 or install all to separate drive files and run any or all if you feel in the mood ;)

System 6.0.7 or 6.0.8 (there's only a printer software difference between these two) because they are fast, economical on RAM use, there's a lot of software that you can run on them and they can use TrueType fonts. Of course there's also a lot of very early Mac software that cannot run on systems as modern as 6.0.x and you may want to install a much earlier OS for those.

System 7.0.1 (as opposed to 7.0) because this is the earliest Mac OS that Disk Copy 6 can run/mount disk images in (I can't live without DC6 in System 7).

No higher than 7.1.1 for me in Mini vMac, beyond this, the System really begins to cramp the total 4MB RAM a Mac Plus can muster.

For me though, the Mini vMac I use the most, is the Mac II variation build, which gives you access to bigger screens, color ranges from mono B/W to millions (I prefer 256 colors here) and a whopping 8MB RAM :)
-Screenshot is mine, Mini vMac Mac II running System 6.0.8, 256 colors.

Thx for the hints MTT, but I'm afraid there is a misunderstanding here. I am (trying to) run(ning) vMac atop B-II, not besides it. So I got indeed the "original" vMac for 68k, as mini vMac seems to have never made it back to the good old MacOS 8.

Which of the three MacPlus ROM versions should I try: v1, v2 or v3?

Ah, one should never assume ;)

ROM 2 is the one I favor. ROM 3 is OK too, hard to tell any difference. ROM 1, I don't have much luck with at all, so I avoid that one and use ROM 2.

Have fun running vMac on your Basilisk II :)

There used to be Mini vMac builds for 68k Mac... this was dropped a few years ago. Someone has bothered to archive a copy at the MG, so it is still possible to run Mini vMac on 68k Macs if needed.

The mini vMac alpha just gives me a black screen with those ROMs. Am I missing something here?.

After some digging around I found a stable release from 2016 on the Web Archive

Direct download: 68k Mini vMac v3.4.1 stable

Sourced via: Mini vMac v3.4.1 stable scroll down page to the classic 68k and PPC versions

Anyway, hope this one delivers :)

Oh, btw. You have to rename any ROM to vMac.ROM <-- if you haven't done this.

Well, vMac works while mini vMac = black screen.

So much for the remake vs. the original. :D

Any experience on how this 68k build runs on actual 68k hardware? Does it do a rather faithful 68000 emulation?

@68040: I wouldn't call a "?" in the screen as working ;)

I've since tried that 68k Mini vMac in Basilisk II and it does work for me. I get a desktop - before I had to junk it - Why junk it? The screen redraw was too slow and the B2 emulated mouse was not working in it. I'll try the older vMac later and see how that goes for me.

@Bolkonskij: I recall trying this some years ago on my Centris 660av and found that it works, but too slowly to be of any use. I would say at best it was a "proof of concept" but no more than that. At least the mouse was almost usable.

I found the classic PPC version on OS 9 fared better. But it was also really slow to update screen refresh, mouse tracking, etc. Until I put in into a RAM disk, then it came alive and ran as smoothly as the host Mac.

@68040: The original vMac v1.9 on Basilisk II works great !!!

So much better than my Mini vMac experiences on B2. Awesome.

Thanks for starting this topic. I would never have tried the old vMac on B2 otherwise.

I'll be trying out on the 660av next :D

Could i ask a stupid question: why would you run mini vmac on an actual 68k machine? Seems like an oxymoron. Like running windows 98 on a windows 98 pc. I’m confused.

So could you run a iifx virtualization on the se/30 and get 68040 performance. That surely isn’t possible. Although could have a iifx running an se/30 i suppose for testing but still, not sure why you would do that.

Running system7 emulation of system7, i’m sure that would port you to the 4th dimension. Lol

Quote from: Neal_SE30, who asked:
" why would you run mini vmac on an actual 68k machine?"
I guess one reason would be, if someone had a 68k Mac that was created in the early to mid 1990's, and they were wanting to run some software that will only run on a b/w mono Mac from the early 1980's. This would be one way to do that, if they didn't own an even earlier Mac.

Probably the main reason though, would be because they can ;)

There are a lot of folks who are just crazy about emulation and getting them up and running.

But no, you won't get better performance than what the host computer can deliver.

Here's a pretty good example range (eMaculation forum), scroll down that page for their screenshots.
