Although I have several vintage laptops, they are purpose-specific; I use them to run DOS and Win3.1 software I can't easily run any other way, so I am not really a vintage computing guy. That said, I also have a SPARC 1 laptop that powers up and boots along with a set of manuals and a couple of CDs. The first issue with it is the screen backlight isn't working, so its a little hard to see the screen or do anything useful. The second issue is the login/password, of course, I do not know.
While it would kind of cool to have a working Sparcbook (I guess), I am not sure (a) it can be fixed, (b) how to get around the login issue, (c) whether it is work fixing.
Any vintage Sparc gurus here want to take a shot at answering any or all of these questions? I'd be happy to post the configuration and more details of what I actually have if anyone is interested.
