What piece of retro tech is your white whale? What do you aspire to own but probably won't ever have the chance to?
I grew up around and was mentored by many DEC veterans. I even work in one of their old manufacturing facilities. I'd love to own a DEC mainframe from their peak in the early 80s. Even a minicomputer is unreasonable for most of us hobbiests. One can dream though
Amiga 4000 with one of those accelerators that comes with a compact flash hard drive adaptor, 128MB of RAM, and an 060 at 65Mhz, plus maybe a retargetable graphics card, as well as as a proper original Commodore CRT monitor, mouse, and keyboard.
