\chapter{Available versions}

Native code versions of \gpm\ are available on the following platforms.
\begin{itemize}
\item Digital Equipment Corporation {\em DECstation} and {\em DECserver} 
	under the ULTRIX/RISC operating system 
\item Digital Equipment Corporation {\em Alpha-AXP\/} under OSF-1.
\item Intel i386/i486/Pentium PCs under SVR4.2 (Novell UnixWare), and
	Windows-NT
\item Sun Microsystems SPARC under Solarix 2.x
\item Silicon Graphics workstations and servers
\item Intel i386/i486/Pentium PCs under Linux 
\item Intel i386/i486/Pentium PCs under OS2 2.x or Warp (using {\em EMX\/})
\item Intel i386/i486/Pentium PCs under MS-DOS (using {\em DJGPP\/})

The last three are available by anonymous ftp for non-commercial use only.
Commercial users, or those wishing to have support must purchase a
licensed version of the software.

The following classic versions of \gpm\ have been released at the time 
of these release notes. 
\begin{itemize}
\item Hewlett-Packard {\em Precision Architecture}\footnote{The
	various company and product names are trademarks of their respective
	companies} (HP 9000/8{\em xx}, and HP 9000/7{\em xx}) under 
	the HP-UX operating system
\item Digital Equipment Corporation {\em DECstation} and {\em DECserver} 
	under the ULTRIX/RISC operating system 
\item all MIPS Corporation workstations and servers under the RISCos 
	operating system. This release also applies to binary compatible
	machines from MIPS Corporation's OEMs, including 
	Control Data and Pyramid Technology
\item Silicon Graphics workstations and servers
\item SONY NEWS workstations (MIPS R3000 processor)
\item SUN SPARC processor workstations and computers (SUN-OS and SOLARIS 2.x)
\item IBM RS6000 Power series of workstations and computers
\end{itemize}

\noindent
As well as these {\em RISC} architecture versions, the following 
versions are available on attractive terms to users with heterogeneous
networks. All these versions are exactly compatible with the {\em RISC}
architecture versions.
\begin{itemize}
\item Hewlett-Packard HP 9000/3{\em xx} and 4{\em x}00 workstations 
	based on Motorola M68{\em k} processors, under HP-UX
\item SONY NEWS workstations based on Motorola M68{\em k} processors
\item Apollo DN3{\em x}00 and DN4{\em x}00 workstations
\item SUN Motorola 68{\em k} based workstations (SUN 3's)
\end{itemize}
\noindent

Finally, an MS-DOS version based on interpreted \dcode\ is available.
This compiler provides a full 32-bit environment on IBM-compatible PCs,
at rather reduced speed. Apart from limits based on memory size, versions
of {\bf gpm-pc} track the development of native \gpm, rather than
classic \gpm.  {\bf gpm-pc} is freeware, and is obtainable by anonymous
ftp from \verb+ftp.fit.qut.edu.au:/pub/gpm_modula2+.

The {\em Alpha-OSF/1\/} version was developed with the assistance of
Digital's {\em Alpha Innovators Program\/} and the Cooperative Research
Centre for Digital Systems Technology (DSTC).
