Yup. We maxed our Tandy (Radio Shack) 286 boxen, juiced to a blistering 8mhz, with 2.5mb RAM. I got blisters from stuffing RAM into daughter boards. https://en.wikipedia.org/wiki/Expanded_memory#Expansion_boards https://en.wikipedia.org/wiki/Expanded_memory#Expansion_boar... Twas early years of PC-based image scanning and processing. We only had 1 image capture board. The boot's POST duration for 2.5mb was ridiculous. So after a cpature, my coworker (hi Tim Hall!) would ever so quickly yank the board out of a running box (now doing image processing) to be used in another box. Multitasking! As I remember it, the jump to 386 (much delayed by Micron's protectionist racket) was the next biggest step up.
