You can still buy a new white-on-blue LCD for Atari Stacy (a 30 years old system). The reason is simple – the same screen is used in multiple medical/industrial devices. The result is better than backlight replacement we did on a different unit although the new screen is glossier. Now we have two fully working machines.
I don’t have much experience with 16-bit Atari computers so I was quite surprised that the system has also some tricks to get more than 16 colors our of the machine. Albeit not as useful as the HAM mode on Amiga, this is still impressive.
