SUMMARY: MAC emulation

I wrote a summary about a week ago, but for some reason it did not get
out. Here it is again.

Original question:

We are interested in finding a mac emulation program to run on our Sun
SPARCstations. Does anyone use one of these applications? Our Mac's
in the lab run System 7. We are looking for a package that is
compatible with that system and most standard macintosh software


I got about 20 answers. All mentioned a product called LIKEN from
Xcelerated Systems (phone: 619 - 576 3080). LIKEN runs MAC System
6.0.7. It does not support color or Multifinder. However it will run
all major MAC applications. Only 1 person mentioned that LIKEN was
"extremely buggy and slow". In general people are happy with the
product. I was told that an upgrade is to be released soon. I
include a mail from SunFlash which describes LIKEN in more detail.

Two replies mentioned a product called QUORUM EQUAL from Quorum
Software (phone: 415 - 323 3111), which is to be released later this
year. MAC applications running with EQUAL adopt the look of the
workstation environment, so that the MAC menus and icons are provided
by the graphical user interface of the host mashine. EQUAL runs System
7. I have no evaluation of the product, since it is yet to be released.

Thanks to all that replied

          Liken - Macintosh Emulation For SPARC machine

SunFLASH Vol 38 #16 February 1992
This is an interesting third party product announcement. Liken
is a product that will allow you to run Mac apps on a Sun just
as DOSwindows or SoftPC allows you to run DOS apps. I think that
Liken is a product of

while Sunburst are a reseller. I Could be wrong, but there is enough
interest in this product that I'll post this article while verifying
the relationship between Sunburst and Xcelerated Systems.
I have an evaluation copy of Liken and it's neat!

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 compatible 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 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

Application Support

Most Macintosh applications run successfully in the Liken environment.
However, 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
