[comp.sys.next] Macintosh emulation

farrar@Neon.Stanford.EDU (David S. Farrar) (01/30/91)

Just a bit of information for those interested in Macintosh emulation for
the NeXT:  The Amiga has a Macintosh emulator called AMAX which is part
hardware, part software.  Don't hold me to the following, but I think it
requires you to buy 64K or 128K Mac ROMs; it plugs into the Amiga's floppy
drive port, and gives you a Mac-floppy drive connector.  Supposedly you
can use the Amiga's floppies (which use IBM-similar recording formats)
to store Mac data, but you need a Mac drive to read/write disks originally
from a Mac (due to the Mac's multiple recording speeds).  There is a new
version AMAX-II, which I think supports hardrives as well.  Although the
Amiga multitasks (even with IBM emulation), Mac emulation takes over the
machine.  

To make this relevant to NeXT, as an observation note that the ROM chip in
AMAX is not connected to the Amiga bus at all -- just to a drive port.  I
suspect that it just copies the ROMs to RAM.  I would speculate that if this
is so, then Mac emulation could be done (in theory) entirely in software
on any 68000 based machine -- including the NeXT.  I'll leave the legal
implications of this speculation to the lawyers.

Correct, the hardware is a simple device which allows a Mac compatible
drives to be connected, and also provides a ROM socket.

>requires you to buy 64K or 128K Mac ROMs; it plugs into the Amiga's floppy

Also correct, but restricted to 64/128k ROMs does mean it's only capable
of emulating the B&W version of Macs.

Yes, it provides its own 800k format that are not recognisable by either
Mac or Amiga under normal operating conditions. They do provide a
transfer software through...

Not quite out yet. It's suppose to be an internal card for A2000 and above
series, and it claims to work with normal Mac disks on a non-variable 
speed Amiga drives.

Yes, and hopefully, ReadySoft will cure this 'problem' soon.

Yes, it spends 30-40 seconds copying the ROM image from the hardware
into some area in memory.

I think so too. Atari ST also has a version of Mac Emulator that works well,
I'm sure a Mac Emulator will be availble for NeXTs.

	AMax II has been out for a while, you're thinking of AMax
II+, which is a card and has the advantages of built-in AppleTalk
connector and the ability to read Mac disks in Amiga drives.
	AMax II is just a different set of software to go with
AMax I which allows for hard drive access and better
compatibility.

I must show my disgust in that copies of "pirate" Macintosh ROMs do
exist (as do pirate copies of the AMAX-II software) in the Amiga
community and all over AMIGA bulletin boards across the nation, and
due to the method in which the AMAX software indeed "reads ROMs into
RAM," users are provided with an often seemingly "fully-functional"
Macintosh.

My question is this:  Legal?  I worked for Apple for 2 years and often
do back in Chicago when I'm not at school.  Obviously the fact that
Amiga (read "Toy") users are so "lucky" (as are ATARI-ST users) to
have in reality a "free Macintosh" (though compatibility is not always
a reality) bothers me...

I assume that System 7.0 has "preventative measures" against such
"emulators," but of course, I'm unsure.

Any response to this news would be great; I'd appreciate a copy
via email to klingspo@holst.cs.colostate.edu

	This is hardly specific to the Amiga. People pirate on
every machine. Copying of that pirate version of AMax II is
illegal both to Apple and to Readysoft, the emulator maker.

	Well, since you say "read Toy" without a smiley you're a
closed-minded idi*t. Not the Amiga is a god-send, but the
opposite position is just as stupid. I'm open to corrections.
	Ignoring that, the legality is a big issue. Assuming the
user bought the ROM like he was supposed to, from his position he
owns the ROM and has a right to use it. The emulator works by
reading the ROMs, copying them into RAM, making a few patches and
running the code.
	The catch comes with the System Software. It says in the
license that the OS can't be used on an emulator without
permission in writing, and there is no chance of getting that.
However, shrink-wrap licensing's validity is in question and
there is no official decision by the courts.
	In other words, this is grey-area. The problem from
Apple's perspective is that it isn't the AMax people's crime. It
is the users crime for loading the OS into an emulator. And then
Apple would have to sue every user individually, which would be
ridiculous. Also, it is possible to call the Amiga a Mac and not
an emulator because it is using Mac coding, not a rewritten
equivalent. Anyway, Apple doesn't want to give the Amiga any
unnecessary coverage.

I'd like to correct at least half of that statement.  The Macintosh
emulator on the Atari ST, Spectre GCR, will now work with a copied
EPROM.  The manufacturer/programmer, Dave Small, programmed it that
way.  He wouldn't divulge the method used as that might allow people
to bypass it, but it won't work with bootleg PROMs.

Additionally, it seems to be at least as compatible as most of the
Mac II's in existance.

I have had AMax since it first came out.  I purchased the ROMs legally from an
Apple ROM distributer, and I have been active in many discussions concerning
this emulator for the past two years.  I had heard that some versions of AMax
were indeed pirated, but it is not nearly as epidemic as you make it out to be.

Most AMax users, and everyone who I've SEEN use AMax, use the 128K Apple ROMs,
purchased entirely legally.  There are major problems with not using the actual
ROMs, including not being able to read actual Mac-formatted disks.  The ROM
cartridge is required for this.

>Macintosh.

Seemingly?  Where do you get this?  My version of AMax-II runs every Mac
program I use at work, and I'm a Mac consultant.

Hm.  I hadn't realized that this was comp.sys.mac.advocacy... Hang on...
Nope.  It's not.  Then I must take offense at this posting.  My Amiga is as
far from being a "toy" as the NeXT is from being obsolete.  It's apparent
that you haven't seen a 3000UX.

>I assume that System 7.0 has "preventative measures" against such

AMax-II Plus is a card for the 2000-3000 series, and I hear that expectations
are rather high that it will be fine while running system 7.

>Any response to this news would be great; I'd appreciate a copy
>via email to klingspo@holst.cs.colostate.edu

Indeed, to tie this to the NeXT, I would be ecstatic if a ROM- or software-
based Mac emulator were to appear on the NeXT.  The Mac OS is bad enough that
we must endure it to be tied to an architecture as archaic as the Macintosh.

I agree. Talk like that belongs in alt.flame, where you will be happily

I don't want to start a mess here, this being a NeXT group. I just want
to mention that when I had my Atari ST, I had to go to an Apple Dealer
and buy Apple ROMs. Apple, to this day, makes no fuss over this.

The day after the PC "lovers" decide that the Mac is here to stay and quit
putting us down for using the Mac. We should all realize that the choice of
computing system should be based on the task it is needed for. In many cases
this is a PC, or a Sun, or Next, or whatever. For my use it is generally a
Mac (although I type this on a Sparcstation...).  Unfortunately, since the
Mac was introduced (I got my 128K in Feb of 1984) the "other guys" have been
taking cheap shots. After a while you get tired of it and strike back.

Is this snobbery? And on whose part?

I chose Mac because I like the machine. It has a good OS, and a great user
interface. I enjoy developing software on it. I don't enjoy developing
software on a PC. Need I say more?

	The person who said "Amiga (read TOY)" was being
snobbish. That is what is generally defined as cheap shot, or
stating a controversial opinion without giving any reasoning.
Trust me, being an Amiga owner we've been dealing with it for
quite a while. It seems to be human nature, for people to join
one group and attack all others.

	When will it go out of style? Never.

	There exist, for both the Atari Mac Emulator and the Amiga Mac
Emulator, pirate-modified versions that read the ROM code from disk.
In other words, they've dumped the ROM to a disk file, and use -that-,
as opposed to the actual ROM chips.

Yes, yes yes.... it's true that they DO exist. I should know, I've
seen them in action...  Besides which there are some serious
limitations of not BUYING the Amax hardware.

AMAX works as such... it has two formats of reading disks. The first
is done with the AMAX hardware and the ROMS and an APPLE MAC drive..
With this setup, you can read, write, move, etc, etc everything Mac..
It's great..

The other format, is as such. Once a MAC program is in memory, it can be 
written into AMAX format. that is, which MACINTOSH programs WORK
SOELY in AMIGA drives. ie: Mac program, written in AMAX format...
 
Get it?

Without the hardware, the reading of a disk right out of a genuine mac
is impossible. If you have the hacked-in AMAX version, you cannot
use Macintosh disks hot outta the mac... they have to be converted - 
either by uploading and downloading them, of by null modem - both,
which must be time consuming and the like...

They *DO* exist, granted.. but the thing to remember is *COMPATIBILITY*..
THE COMPATIBILITY factor without the hardware and roms is limited, because
you cant for instance, write a program on AMAX and give the disk
to your MacinBuddy... It wont happen. 

It has to be converted, etc etc - and I dont think too many people will
actually go thru the trouble of converting stuff thru modem or cable
EACH TIME They wish to yap with a real mac... it's a pain in the butt.

If you have any questions about AMAX, i'd be glad to answer them to
clear this up...

First of all, I have not seen one pirate of the Macintosh ROMs on any bulletin
board in Spokane (second largest city in Washington state) nor have I seen one
pirate copy of AMAX-II.  

Second of all, where is your justification in calling the Amiga a toy?  Tell
me, I want to know how my performing class programming assignments, producing
documents, producing applications, playing an occasional game, along with my
wife's production of professional artwork and documents describes my Amiga as
a toy.  Being a CS major, you SHOULD now that there is no one computer for all
jobs, and that even though one computer has an edge over another computer in 
one area, the same computer is more than likely inferior to the other in another
area.

I know that this does not belong here, but I am an Amiga owner and a NeXT user
that enjoys this area of the net, but get quite annoyed by persons who make the 
ignorant statements like the one above by Mr. Klingsporn.

Just my 2 cents worth

Actually, I've seen a version of the Amax (and Amax-II) that have been
slightly "modified" so that the ROMs are no longer needed. The entire ROM 
is loaded from floppy on bootup, and then the executing code is told 
where to look...it actually works!!
