If there are any Z80s in the Space Shuttle at all, it's not in the critical system. The original board computer was actually based on the S/360 mainframe, which was already know to be reliable when the shuttle programme started. In fact, the z80 didn't even exist back when the programme started. Over time the systems have been upgraden a few times. I think currently a lot of systems run on 386 procs.

question is how much cpu power you need to operate/drive/fly a shuttle .. It's the rocket-motors that do the work. You might want to read out the status of a motor ... do you need rocketscience for that?

it made calculations that a human could not do the flight system..... but i gues my friend discovery science gave me the wrong info...

In the early days, computations were not done in realtime, flight programmes were calculated before they were needed.

But to get back to topic. For a realistic pinball simulation just having some bounce calculations is not enough. It's the spin/friction calculations that give it the edge. I'm pretty sure the z80 can't handle that in realtime.

im pretty sure it is doable
de ball moves to l/r and the tabel vertical......

This debate makes me wanna know more about MSX applications/games with realtime phisical modeling. I remember on game, where You hit the small ball and it runs pretty fast across all the screen. I think it was in a little labyrinth.. remember?

A long long time ago (in a country far far away) I made some tracks for a pinball game called Mental Meltdown. Project never took of, but I'd really love to do music for a pinball game. MoonSound music anyone?
Lets get this thing started!

I've been wanting to do that for yeeeeeaaaaars, really. And could be a piece of cake on Gfx9000.

How about it, Aurora? Why not start this? I've been wanting to make a pinball game for years too. I could do the music / sounds. Don't have a GFX 9000 but I could do MSX-2 graphics.

Well, there's a lot of other stuff on my todo list needing attention, so I have barely any time left to spend on another MSX project But ehm... I'd say: let's have a chat about it @ Bussum

There is one Pinball game missing......

Years ago I saw picture of MSX Pinball game in some finnish magazine... only thing i do remember about that pic is that it has word "PINBALL" on the edge of the screen and word´s colour was 4 aka dark blue and there were just outlines of those letters.

So, what game is it?! I still have never seen it !

(Screenshots please!)

It depends what do you mean "when the programme started".

Shuttle programme originally started on January 1972 and first shuttle, Columbia was ready in 1979 and has it´s first launch in 1981.

Z80 was published in 1976.

So I guess that IF you mean original starting from the scratch date 1972, then there was no Z80, but I guess as computers got more advanced during years they probably ended to put more advanced computers to shuttle compared to ones that were available in 1972.

But if you meant it´s launch date or date when it´s construction was finished, then there WAS thing called Z80!

I meant started as in '72. And no, they were not in a hurry to put more advanced technology in there. Tried and tested was the way to go.

You´re probably right, edwin.
