AST Advantage! NB 486SX/33
The AST Advantage! NB 486SX/33 is a 486-based laptop that was released in 1994.
These are fairly common based on how many are on eBay. These were rebadged Twinhead Slimnot4e 486 laptops. This same laptop was rebadged and sold by multiple other companies as well, including Compudyne. It's notable due to the very odd trackball placement - above the keyboard and a little to the left. Such a weird place for it.
There are some more photos of this machine here.
An internal photo shown in an eBay listing looked like it might have had a few leaking caps inside, so that's something to note. I also saw what appeared to be a supercapacitor, so it may have used that as a CMOS battery.
