Quote from: Bolkonskij, who inquired:
" Any experience on how this 68k build runs on actual 68k hardware? Does it do a rather faithful 68000 emulation?"
I just tried the older vMac on the 660av. It is s-l-o-w-w-w-w... Not at all like how it performs on Basilisk II running Mac OS 8.1, which runs acceptably smoothly.

I find on the 660av the lag before anything happens, e.g. move your mouse and wait seconds for the emulated cursor to catch up. Or close a window or click a button, you need to hold the mouse down until you see a physical reaction, before letting the mouse go.

I don't think I'll be playing Perplexx any time soon on this ;)

OTOH, on Basilisk II running on a modern system, not a problem.

Interesting to note too, on the 660av, a different version runs, than what runs on what it thinks is an '040 Mac (B2). It is FAT encoded, which must include PPC as well as 68k, but there are two different 68k types in there. On B2 the build "Loud Harmonicas" runs. On the 660av the build "Lonely Heifers" runs ;)

@68040: I think I know why you get a black screen with Mini vMac. It's waiting for you to give it a bootable disk image to load. Drag and drop a boot image into it's window.

[Edit:] Nope I retract that, Mini vMac simply ain't working on my 660av. It kind of works on my B2, but the older vMac is the way to go here.

@MTT - The only reason why I got a '?' disk icon in my boot screen is that I haven't figured out a good System 7 boot disj yet. But the ROM loads fine and that means to me this baby is ready2rock.

PS: I am the kind a guy who loves to "start things" ;)

@Neal_SE30 - Why would you climb a mountain? Because its there. :D

Rather than emulate a 68k on a 68k. Can you not just use boot camp or something like that and have several operating systems on a large SD split into partitions?
That way you could have system 6.0.3, 7.1 & 7.5.5 or is that not possible.

I have a Rominator although i’ve never used it due to it not liking 7.5.5 unless you put it on 7.5.3 first before upgrading to 7.5.5 allows multiple os. that has 7.1 on it so you can boot into that or the hhd so I presumed you could pop on several operating systems. That is something i wanted to do when i upgrade mine at the end of the month.

Not a lot an se/30 could emulate, a 128 or a 512 both pretty useless for actually doing anything on, add said lag it would be awful lol.

I suppose if you had some hi end later machine you could emulate an early compact. I can see why if was abandoned. Still wonderful someone wrote it anyway 😆

Where this would be interesting is emulating essentially a 512k Mac with some Finder/System prior to System 6. There's a handful of software (especially games) that just ran on stuff < 6.

Anyway, thanks for reporting back on the performance @MTT. One of those days I'll give it a try on both my 8600 and my IIci.
