#amax4 w/ roms for sale

Bob,
I'm curious as to how much memory is required on the Amiga to run Amax.
Also, is there a speed tradeoff in emulation?
Thanks,
Tim
Tim,
Amax like Emplant will run at the same speed as the underlying CPU. If
you have a 25Mhz '030, the Mac side will run at the same speed, there is no
tradeoff. As for memory requirements, the emulators require that ram be in a
contiguous chunk, same as the Mac. So the amount of ram available to the
emulation is the maximum contiguous chunk available at the time the emulation
is started. You should plan on at least 8 meg of fast ram to have at least
enough for a reasonable emulation. More is better, but with 8 megs to start
and not a lot of ram being allocated to Amiga programs you should be able to
get close to 5 or 6 meg on the emulation in a typical setup. The less ram used
by the Amiga, the more will be available to the emulation. Of course you will
allocate less ram to the emulation if you need to preserve ram for the Amiga
side during emulation. Amax IV needs an '030 with MMU and preferably 32 bit
ram, althoug it may run with 16 bit ram, I'm not sure.
Steven,
Thanks for the detailed reply about amax emulation.

Hi. A couple of small corrections and additions to the previous posts. The AMAX
IV does not require a MMU. If you have one, it will use it, but it is not
required.
As for 32 and 16 bit ram, the AMAX IV will use 16 bit ram, as that is how it
is working on my setup. The problem is that it is very slow, about 1.5 times
the speed of a Mac Classic. I am buying a new accel. that will hold more 32 bit
ram, as the 2 on my MMR does not cut it.

Well my original buyer seems to have disappeared, so:
A-Max IV with 128K Mac ROMs: $300 _with_ original Apple System 7.1 disk
set, $285 without.
Prices firm. 🙂
Denny;
Sorry, but I already bought another one.
Hope I can do business with you in the future.
George
Thanks for your reply.
