All,
Here is my chart again with a better format. It does not look correct in this format, you must put in another editor - see below. The end of each line is marked by a ' char. The spaces are marked by a full stop. You MUST view the file in a font / editor that uses the same width for each character (otherwise the years don't line up)
To reconstruct put the text into notepad or similar, turn off word wrap and delete any extra 'new line' chars until the end of each line is terminated by '.
I have done some of the hard work, maybe someone could put more accurate release / termination dates in (to the nearest quarter). I have not included the desk top or palm top machines as they do not interest me.
The 'lost years' between 91 and 98 are very obvious.
Tom.
