Never had a Viglen, used to have plenty of Elonexs though. Our first PC at work was a Tandy DeskMate running Dos 3.3, bloody indestructible that thing. We then had a huge failure with a Nixdorf mini computer where the software didn't work. Our first proper computer was a Xenix machine made by Mission (the speaker manufacturer) it had a 20 Mb HDD and 1 Mb RAM, 5.25" floppy drive too!
