"Atari XE/XL" as in "Atari 8-bit". The XEs/XLs were way more popular in Poland than the 400s/800s.
The Polish continued to buy 8-bit XE's when the rest of the first world was moving to 16-bit in the early 90s (68000, 286). They weren't missing out on much in my opinion; I think 16-bit for both computing and consoles didn't add much. Once the 386sx arrived it made the PC truly affordable and capable; the software system was still 16-bit DOS/Win3, and these PC's were ready and waiting for 32-bit software, which with the birth of Linux and BSD catapulted the PC into the true computing age.
