Linux Desktop on Apple Silicon/M1 in Practice

I bought M1 MacBook Air. It is the fastest computer I have, and I have been a GNOME/GNU/Linux user for long time. It is obvious conclusion that I need practical Linux desktop environment on Apple Silicon/M1.

Fortunately, Linux already works on Apple Silicon/M1. But how practical is it?

Two native ports exist.

OpenVMS is an operating system originally developed by DEC (Digital Equipment Corporation), a company acquired by Compaq which was then acquired by HP for the VAX platform.

Although development started in the mid-1970s into the 1980s, OpenVMS is still very much alive with up-to version 7.3 available for VAX, and continued development in 8.x for DEC Alpha and now Intel Itanium architectures. Even Oracle, who acquired DEC's Rdb RDBMS have stated that they will continue to support and develop Rdb, creating a lesser gap between it and Oracle Database system

Welcome to the second part of Getting Started with OpenVMS and SIMH. This article assumes that you have already followed part 1 or have at least installed OpenVMS VAX 7.3 on a system, with dua0 containing the OS, dua1 containing user-directories, and TCP/IP services are functional. If in doubt, have a quick read over what we did in the first part. For this part, we will install and use UNZIP, wget, Compaq C and the WASD HTTP server.

Although I'd /love/ to throw you in at the deep-end, I think the transition to OpenVMS will be easier if we introduce a couple of utilities you may be familiar with and break you in gently. This is a bit of a 'ghetto' guide to OpenVMS 7.3, and is primarily for users learning through SIMH - so, we will use the easiest methods of retrieving and installing what we need (despite them not being the most traditional methods).

UNZIP & WGET

These two utilities, in my opini
