Retrocomputing has now made it to the Style section of the New York Times. There is nothing particularly new about the article, except where it appeared. I guess people have noticed that retrocomputing is a thing, and that old gear is quickly turning into collectibles.
For my own part, I was very lucky that the OS/2 Museum acquired some equipment before retrocomputing was a thing. For example PS/2 machines are now worth hundreds of dollars, and I got a few at a time when shipping cost more than the machine.
These days, I find that prices of 5-10 year old server gear can be surprisingly low, although high-end desktop boards and CPUs still sell for surprisingly high prices (Core 2 Extreme, Core i7 Extreme) that never dropped down enough to reflect their actual practical value. Interesting times.
