These are release dates and end-of-sales dates for computers in my collection. While release dates are relatively easy to find, end-of-sales dates prove significantly more difficult to research.
There is little, to no, information for the Compaq Portables and Sun SPARCstations with regard to their ending sales dates. If you have corrections or additional information, please let me know.
The chart shows computers currently in the collection with solid bars, and computers not yet in the collection with outline bars. The horizontal span of each bar represents the period during which that computer was actively sold.
