You are aware that left and right Amiga keys each have very specific, dedicated functionality? Broadly described, right Amiga key is for program hotkeys, while left Amiga key is for Intuition (the Amiga GUI) hotkeys.

I use AmTelnet as well as AmiTCP telnet - with Roadshow, which btw also includes a simple, but extremely useful rsh client.

On the linux side I have a loop back mounted disk image with Gentoo/Linux on, from which OpenRC is ran chrooted on boot (from inittab), with all services I wish (including telnetd, rshd etc).

We’re all eagerly awaiting your return, hehe

I read in PiStorm updates about improved Musashi (20-30%)
I suspect the improvements are only in the pistorm git repo, and not gone upstream.

Did anyone build for Minimig_hybrid yet?

New filesystem should work just fine with kickstart 3.0, but you _HAVE_ you install v47 fastfilesystem to RDB on the hard drive, using HDToolBox. This is nothing new, and it is exactly the same way with PFS as well. (I was always puzzled by the expression "works like a charm", as charms don't really work well, scientifically...) To the R...

I use PeterK’s icon.library 46.4… don’t know what else could make a difference.

Oh - Piru’s “WhichAmiga” makes the Minimig freeze here.

Yes

I have set up 3.1.4(.1) and using 68040.library from OS 3.1 (for some reason, 68040.library (44.2) from OS 3.9 doesn’t load) and I don’t have any issues with clicking or double clicking.

@foft

What kind of crashes do you see? Freeze? System failure with red alert? If so, what error code? All kinds of icons?

I ask since I don't really see such crashes myself.

EdIt: ah, ok, I see... so it happens when double clicking, regardless of where the pointer is?
Only thing I see here is that the mouse pointer is somewhat jerky and lagging.

The cause for the crashes (8000 000B) are the mathlibs, which may try to use calls for the 68881/68882 that isn’t available. 68040.library traps those calls that aren’t available on 040 and perform them in software instead (essentially 68881/68882 emulation). There are mathlibs that do not use FPU, and hence will not cause such problems - I wonder ...

I tried using the 3.1.4 ROM from Hyperion and the Workbench that comes with it, but it still had the problem with clicking icons even though the install disk should have a 68040 library. OS 3.1.4 does NOT come with 68040.library, you are supposed to install CPU libraries from CPU card provider - or the CPU libraries from ThoR (MMULib). Running Ami...

OK, here is a new core and kernel module. http://www.64kib.com/minimig_irq_core.tar.gz Where do I find the sources for this module? As I wrote earlier, I build my own kernels, and hence the "magic version" is different than the "official" kernel :) /root# insmod /media/fat/Amiga/minimig_module/minimig-irq.ko insmod: ERROR: coul...

So JIT and MMU? In other 68k emulators those have been mutually exclusive - either super fast JIT or relatively slow “non JIT”, but with MMU.

There is no JIT option for qemu, I guess?

Can’t expect too much when emulating full 040 with MMU and (hence) no JIT

Regarding the 68040 libraries, I think the problem with the mmulib ones are either the mmu, or perhaps that it tries to “fix” known issues with the real 68040s that aren’t necessarily there with a software emulated 68040…

Oh, use 68040.library from OS 3.1, it works

I wanted to ask earlier, what is the reason for using system mode? Normallly, system mode is used for emulating a particular hardware configuration in addition to CPU, but is that really the case here? Thinking a little more, I suppose it is - interfaces to the real hardware only exists in system-mode I guess :) Btw - I am ready to try out the new ...

What FPU emulator is this?

See earlier discussions here, any time you see “musashi” mentioned, it’s the pistorm emulator

What I find really strange is how all benchmarks say everything is much faster than tg68, while in reality it is so much slower, heh...

Noone really has a working setup yet, we are all experimenting. Btw you don’t need ssh, you can just press F9 in the menu core, log in and start the 68k emulation from there, after for example a 20 sec sleep, enough so you can F12 and start the hybrid core before CPU emulation kicks in.

Some first impressions... :) * turned off PPP, set UART to "none" (does it matter? I see no difference really) * more or less untampered OS 3.1.4.1 * turned off Minimig RTG, use P96 with "native" driver and HD720 mode (32 pens) * installed CPU libraries (+ mmu.library - http://aminet.net/package/util/sys/Mu680x0Libs) * with musa...

I have some test code that was used to find bugs in tg68, which surely can be used again, and also software that use FPU... what kind of precision can we expect?

If you cannot understand, then just wait till it is ready for end-users.

Where is the Sysinfo screenshot!

Just thinking outside the box (literally)... What's the capability of the IO header on the DE10-Nano? It's fast/capable enough for SDRAM; would it be fast enough for a RAM+CPU board, like we used to have in trapdoor expansion for amiga 1200 and the like? i.e., for those who really want a faster CPU in their simulated amiga, would it be feasible fo...

sounds like what some people really want are 68k MMU and FPU. and if you’re running amigaOS both are mostly irrelevant. Not really - FPU is supported and is used when available, by OS libraries. But that is really beside the point, which is that there is plenty of SOFTWARE that not just use FPU, but sometimes require FPU. If all you want to use Am...

Back in the days (mid 90ies) some fellow computer student friends and I concluded that the probably easiest and cheapest way for us to get faster Amigas, would be to use mind altering drugs that changed our own perception of time - maybe something to consider, hehe
