A lovely TI99/4 (minus the A) at the #Bonami computer museum in #Zwolle, #Netherlands.
That's right, it's not a TI99/4A.
I newer saw one in the flesh before.

@RetroWizzard the only difference is the video chip, isn't it?

A PAL/NTSC difference or something else? I wrote my first code on a 4A when I was 7 😁

Thank you for this, I thought it sounded familiar but just realised now that it's been used in the SG-1000 as well.
