The more I see of this article...
...and the more I see of the fotos, and the more I read these comments, the harder I'm kicking myself over having donated my old Mac Plus to Goodwill about fifteen years ago, for all of a $100 tax writeoff. I didn't think anything of it at the time; while it worked fine, it was past its seriously productive life, and I needed the tax writeoff, so I donated the thing.
I fired everything up one last time to make sure it all still worked (and it did, like a champ) before I donated the whole kaboodle -- Mac Plus, keyboard, mouse, full set of OS and app software, ThunderScan snap-in head, ImageWriter II, in one of those really cool padded nylon cases.
It pisses me off now, to think of it -- a 25 year-old Mac Plus with OS7.0.1 with a massive 4mb of memory, PageMaker 4, MacDraw 7, MSWord, ThunderScan, ImageStudio, some early Internet client apps, two 800k floppies and a 20mb SCSI drive, all in perfect working condition -- and how much it might be worth now. Goddammit (kick!).
But, aaa-aaanyway, enough pining over my old Plus; this exhibit is largely about old British iron, though. An old programmer buddy of mine had the ultra-small Sinclair ZX, which was fairly popular in the States in the early '80s -- sold under the "Timex/Sinclair" brand, as I recall -- and being an übergeek, he managed to get that puppy to do some pretty cool shit. And, oh, that keyboard, with an action and response not unlike an early fast-food cash register.
