As it is, I just make a master brain robot for the ship's AI and allow it to have immobile slaves attached to various computer terminals around the ship, so that non-capital ships have the bandwidth to get a voice activated personality.
That's covered in Robot Handbook.
Also, for the updated Central Supply Catalogue, I also added a bit more about retrotech electronics and computers (retro only applies to them, but proto applies to anything). And some more computers ('mid-sized' to cover anything from a PDP-11 to a modern blade server) and rules for making 'supercomputers'. Nothing that changes the basic dynamic of how computers work in Traveller, though. I'll have to see if it all survives the edit.
There are definitely some 'legacy' issues with Traveller computers. They actually have evolved since the classic books, but they still carry some of that baggage, which I've tried to rationalize, but need to retain for 'game balance'. And given how wrong people were about computer evolution 45 years ago, can we really say that we know where they will be in 45 years - Moore's law is slowly flattening into an s-curve. Could be worse: did anyone else ever read H. Beam Piper's Cosmic Computer (a.k.a. Junkyard Planet) ?
Spoiler alert: The computer was built into the walls. That was a big 'surprise' in 1963 when it was written, but by the time I read it about 20 years later, it was already silly, even though back then all I had was a Commodore 64 and a 300 baud modem... and an Epson dot-matrix printer that still haunts my basement.
