The answer is very simple. There is one product, named Liken. The day after
I posted the question I was called by the Dutch distributer of this
and all the other answers say basically the same.

Liken emulates a Mac Plus in an X-window on your screen. Mac HD disks are
supported, colour is not, neither is sound. System 7 is being worked at.
>From the answers I got the impression that it works neat and is compatible
with most of the macintosh applications. The price is quite steep, in my
opinion: the equivalent of $1600 (*in The Netherlands*, in the US it is
$695). This makes a Mac Classic next to your Sun a cheap competitior.

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
