Mac Emulator LIKEN ---> (SUMMARY)

From: Pankaj Narayan (
Date: Fri May 29 1992 - 11:39:20 CDT

All in all, seems to be worth an evaluation at least.....

=========ORIGINAL ARTICLE ===============================================
LIKEN is a Mac-emulator that runs Mac applications on a SPARC under X-windows.
It costs $700 for a single floating license.

I am thinking of convincing people here to get one, at least on an evaluation basis.
Please send me your experiences with it if you are or have been a user of the product.
I would like to know what system you were running it on (Sun 4 ? How much RAM ?) and
which Macintosh applications you ran. And how the performace was - was it too unbearably
slow ? Or was it fast enough to be un-noticeable ? Your responses will really help !

PLEASE MAIL YOUR RESPONSES, since I don't subscribe to all of these groups.

Thanks in advance.

-------------------RESPONSES -----------------------------------------

I've been evaluating LIKEN for about 6 weeks. I'm now ordering it.

LIKEN does a real good job of emulating a standalone Mac classic with
4MB running system 6. LIKEN does not (yet) talk appletalk, quickmail,
etc. LIKEN won't do system 7 yet either. They say they are working
on those.

My tests have not been extensive, consisting of Word, PowerPoint, and
and a locally developed software package.


Speed on my Sparc IPX (one of the fast Suns) is much better than the
Mac Classic it emulates, but slower at drawing the screen than a
MacIIcx. Some things run real fast, a big disk copy seems to be
faster than Quadra 700 (betcha it uses SunOS calls). Really looks and
acts like a Mac. Fast enough, basically.

The company is a pleasure to deal with. They have been generous with
my evaluation period. Their technical support is superb (and free).
They are on release 1.2 now, seem to be upgrading rapidly. If you buy
now, get the software maintenance for another $140.

LIKEN can do things that a Mac can't. The desktop can be resized like
other Xwindows, up to the full Sun screen. I use it full screen with
a virtual desktop, so I can pop to other screens of Xwindows and back.
Liken can read and write to a Unix directory, which is real important
for me. I think that the newest release can also cut and paste
between other Xwindows.

Printing is via standard lpr to a Laserwriter or Sun postscript printer.


I've had some problems with PowerPoint misdisplaying odd sized fonts
(ie- 20 point helvetica) when in Full View mode, it worked at 66%.
This is allegedly fixed in their latest release. It will only read
high density floppies (2MB, can't read the 1MB). Be sure your Sun has
a 3.5 floppy drive. Beware, most software packages seem to be
distributed on 1MB disks, so must be copied on a real Mac. Won't yet
run TrueType fonts. It is still pretty new, other bugs are probably
lurking. Runs MacFTP, but won't do quickmail.

Liken software allows Macintosh applications to be run on Sun
Microsystems and compatiable SPARC workstations. Within the Liken
environment, workstation users can freely move between UNIX and
Macintosh applications and access the vast library of Macintosh
application software.

The Liken solution allows most Macintosh applications which run on a
monochrome 68000 machine to operate without modification in an X-window
on the SPARC desktop.

Liken adds dimensions of compatibility and interoperation to the open
systems architecture.

o Run CLARIS FileMaker Pro, MacProject, MacWrite and MacDraw
        Word, Excel, and Powerpoint, Aldus Pagemaker... the list is
        long and growing

o Use accessories like Adobe Type Manager, Suitcase II, and
        Tempo II

o Files stored on floppy, CDROM, hard disk or Network File System
        (NFS) in UNIX or Macintosh Formats

o Window size adjustable from 512 by 342 pixels to 1152 by 900

o Enlarged display mode for easier reading and accurate placement

o Performance on a 24MB SPARCstation IPX Similar to a 16Mhz 68030

Supported Devices

Printing Apple Laserwriter or compatible Postscript Printer via
                SunOS "lpr" spooling system.

Hard Disk Any file accessible through the SunOS file system, on
                any media supported by SunOS system. HFS-compatible
                hard disk volumes are stored within a SunOS file system
                container file.

                are not supported by Sun hardware) in the Apple
                HFS-compatible format.

Display/Window The Liken X-window may range in size from 512 x 342
                pixels to 1152 x 900 pixels, as a portrait, landscape, or
                two-up display. This window is seen by Liken applications
                as the display size. The application works in monochrome
                only, although Liken allows the use of color workstations.

Keyboard/Mouse Any SunOS X-window supported device

Graphics Accelerator
                Used as available to improve drawing speeds

Network File system access using NFS allows direct reference to
                files located on different machines.

Thanks for your inquiry. The following is information on Liken. If
you have any questions, please call or e-mail me.

                                   Liken TM

Liken is a SunOS application that runs Apple Macintosh applications and
Macintosh System Software such as Finder and the Desktop Accessories on a SPARC
workstation. Liken provides an easy to use environment for Macintosh compat-
ible applications.

Liken provides an emulation of a Motorola 68000 processor, and allows the use
of the SPARC display, keyboard, mouse, hard disk, floppy disk, and CDROM
drives. Liken runs under the Open Windows SunOS windowing system (and Motif)
and is specifically designed to operate with customer-supplied Apple Macintosh
System Software v. 6.0.7.


The environment provided by Liken is similar to a Macintosh Classic with 4 MB
of memory, one floppy disk, an optional CDROM disk and multiple hard disks.
The Liken window size is adjustable from that of a Macintosh Classic screen
size (512 pixels wide by 342 pixels high) to that of the Sun screen (1152 wide
by 900 high). Liken uses the left most Sun mouse button as the Macintosh
single button. Liken provides the same functionality as the Extended Macintosh
keyboard using the Sun keyboard.

Application Support

Most Macintosh applications run successfully in the Liken environment. How-
ever, because of the physical differences between a Macintosh and a SPARC
workstation as well as the different capabilities provided by the SunOS
operating system, some restrictions arise. Only high density floppy diskettes
are supported. Color applications which run on a monochrome Macintosh Classic
should work under Liken. Applications sound support is equivalent to running
with the sound turned off. Macintosh applications requiring Macintosh specific
communication hardware are not supported due to the differences in the physical
capabilities of the SPARC workstation.

Liken supports applications which conform to the standard published guidelines.
If an application is dependent on a specific model of computer, it may not work
under Liken. However, if an application has been written to work on all
models, then it is expected to work.

The SPARC hardware environment is utilized by the Liken program. Therefore,
the only possible devices which can be supported are those which are available
on the SPARC. The applications running in the Liken environment are provided
access to hardware devices though standard driver interfaces or through the
file system. If an application assumes the presence of particular hardware and
attempts to manipulate it is likely to run into difficulties.

Applications which determine if the display is color or monochrome through the
standard drawing interface should function. Liken only supports black and
white mode and returns this indication to the application. Applications which
make assumptions about the physical hardware display and attempt to manipulate
the display are likely to fail.

Dear Dieter

> 1. Are there any reports or test on Linken available?

There have been evaluations of Liken done by Open Systems Today and Sun World. I can send you copies if you'd liken them.

Yes, Word 5.0 works great. The performance depends on your SPARCstation. On and IPC it's similar to a Mac Classic. On and IPX, it's similar to a Mac IIsi.

> 6. Which is the latest Version of Linken?

Version 1.2 just started shipping this week. It includes a new floating license version, support for networking, and cut and paste between Unix and Mac applications.

Please let me know if you have questions of would like ordering information.

We've only tested it REAL superficially. Seems to work. Ran it on a 4/40 with 24 Mbytes. My wild guess (not being much of a macaholic) is that it acts about like a MAC classic.

We haven't had a chance to try many different software packages on it yet.

It's neat, but does have major limitations. Claims of Classic speed are generous, and the most major limitation is the absence of any network support, which for *me* means I have to keep a Mac on my desk (to read QuickMail, inter alia). It also only runs System 6.0.7.

Version 2.0 (the screen dumps of which were used in the ver 1.0 manual!) will provide system 7.0 (debate on worth of sys 7 to comp.mac.system please!), and a much needed speed increase. Also implemented should be networking capability, but I fail to see how this can be straightforward.

So, at the moment, I find it almost useful, but not good enough to work on for anything major ... a trusty LC with Pivot suffices, or I use my IPX.

I've put Liken 1.0 on an SS-2 with 32 megs of RAM under SunOS 4.1.2, and I found the speed to be faster than any Macintosh I've ever used. The only application I ran was Microsoft Word, and this was very quick. The reason I have not tested it with other applications is that Liken has no communications capability yet, and to be truly worthwhile in our environment, it will have to be able to do AppleTalk and probably Mac TCP.

The worst bug I noticed was that sometimes Liken complains at boot up time about not being able to resize windows while an application is running. When this happens, it may take several minutes for the program to finish initializing. Normally, booting this pseudo Mac takes only a few seconds at most.

I think you can get an evaluation copy for free. That's probably all you'll need. We found that on a Sparcstation 2, the response was unbearably slow. (One typical unbearable application was StuffIt, which we used quite often to bring stuff from Unix files into the virtual Mac disk.) It also has some major drawbacks, like it only emulates a Mac Classic with 4 Mb of memory, and the Multi-Finder doesn't work. It's really nice for being able to read Mac disks on a Sun, but it's not worth $700 for that.
