I am thinking of buying one to run my maths progs that I created on a 4000 040 with a math coprocessor. Would it be faster? If so by how much?


depending on the programs you have in mind the question arises how much is it worth for you to see them working how much faster. probably, considering price-performance ratio some sort of pc emu like winuae/jit would be your best bet.

Thanks for your response. I've never seen one of these emulators work. Are they really OK, or do they have some operating limitation?


why, you can simply download winuae or fs-uae for that matter and simply run them on your windows, mac (?) or linux. the usage is pretty straightfroward, you only need to get hold of amiga kickstart images, either read them out from your genuine hardware, or buy them form an official distributor like cloanto or simply use aros replacement kickstart which is free and will be usually sufficient for regular amiga (68k) software.

now, what concerns performance, to be a bit more precize about what i wrote, i assumed you want simply run your existing amiga (68k) binaries. in which case emulation on x86 is clearly superior in terms of speed. i was not talking about running ppc code, which you might compile assuming you still have your sources, in which case you would lose the advantage of thebrute force computing power of x86, because ppc emulation is apparently slower than 68k, but you might gain a bit on ppc hardware.

nevertheless if you have your sources at hand you might as well compile native x86/x64 binaries, against amiga api, such as aros x86/x64 and run them natively or hosted on a pc, which again would be the fastest option.

however, this all are probably too dry technical considerations, while most users base their decisions on sort of sentiment, being it whether the genuine amiga or ppc, their choice of operating system, loyalty to a certain fraction or whatever.

I wrote my progs many years ago using HiSoft basic compiled.

in this case it seems the choice is between running a genuine 68k binary or recompiling it for the target architecture. in which case you might need to adapt your code to the available basic compilers for particular platform. alas i cant tell much of the current state of basic implementations for ppc systems running os4. i can see that aros has bwbasic and cbmbasic sources in ports, but i dont have any experience with those and do not even know if they are being interpreted or compiled. i could just build them for x86 and 68k just to check out what they are, admittedly.

I am worried that an emulator on a laptop would overheat if run all the time and would not be as quick as the new X5000.


i would rather worry that x5000 is not as fast as a second or third hand budget pc in executing 68k code, and that in case of overheat under constant load the hardware replacement cost might be considerably higher and the replacement availability might be far less secure than some pc laptop. but then its your own reasoning and choice.

bwbasic and cbmbasic


ok, just compiled them for m68k and baywater basic is an interpreter and cbm basic is basically for c64, lol, detects 64k ram no matter what. so no use i guess.

@outrun
looked at that very briefly, seems to be instructions on setting up your graphics with ppc euae. this is not performance wise of any issue with any emultion i use on x86/x64, neither on host not even under vm. i doubt is has any signicicant impact on simple cpu dependant number crunching tasks as seem to be subject for alphagemini.

scroll down a bit to karlos post #5 with the results for the same binary with euae on an apparently rather old lower end core2 pc. as you see that old pc beats all ppc hardware inclusive g4 (g5 might be a bit faster) in 68k emulation. (x5000 seems roughly comparable to x1000, it might be a bit faster in some areas but, slower in others, i think it doesnt have altivec for instance). according to this number crunching test aeon ppc hardware plays speed wise in the same category as g4 based apple products.

Thanks for your help. I will struggle on trying to get my 4000 040 back on but I am very tempted to get the x5000!!


a4k is a very fine machine, you need to look at the board though to determine if the battery and the capacitors dont leak, rtc battery should be usually removed asap.

im not sure though if i would impose number crunching tasks on it these days. excuse me that blatant advertising, but vampire stand alone might interest you:

note that i dont have this hardware and cant report its abilities first hand. one should be very cautious with that sort of things, i admit.

This is beyond my comprehension, what is AFAIK and qemu?

"afaik" is an acronym for "as far as i know" and qemu (as far as i know) is an emulation engine.
