Amiga questions you've always been too embarrassed to ask

I already said. It wouldn't be a "port". It would be a rewrite from scratch.
So it's a matter of how long it would take to make this game from scratch.

The only things that would save them time, is the storyboard (or platform map, or whatever is kept the same) would be reused - the idea.

Also it is possible that some of the original graphics/sprites could be used as base (i.e. draw over them to make them look similar).

Emulation would be VERY slow for gaming - since you mentioned it.
C64 emulators were all slow on normal 68k Amigas.

The term used for going between totally incompatible platforms back in the day was "conversion". :-)

Right on.

not amiga related but..
there are different versions of the 1084s monitor.
1084s d1, d2, p1, p2 and so on..for amiga users, it's not a problem, they all work well. but I've read that the commodore 128 80 column is supported only by 1084s d1 and p1.
so what happens when you connect the commodore 128 to a 1084s d2? no picture? 40 column?

If the 1084S D2 does not support the C128 80 column mode then that is because it lacks the RGB TTL input.

When you fit an accelerator card to the A1200 you are adding another processor.
What is the original one doing?
Could it be utilised for other functions like a modern day dual core processor?

Have I discovered a neat idea no one else has thought of..If so I must deserve a Nobel prize or something similar?

The accelerator takes over the system, the on-board CPU does nothing. The architecture does not allow for both CPUs to run; if they tried, all accesses to RAM and other shared resources would result in garbage.

The old PPC accelerators did have both a 68k CPU and a PPC CPU which run side by side, but they still need to share the memory bus so software needs to be written with this in mind.

Shame seems like a waste of CPU!

Who here says Amiga 1200 like "Amiga One thousand two hundred" instead of "Amiga twelve hundred"?

I think you're on your own on that one!

What do you call a 4 CPU 5 core Amiga (1x68060 1xppc604e 1xppc7410 and 2xARM A9)?

This thing has gone out of hand

[Estrayk]

QUESTION: I read a long time ago that 68040 processors can benefit from L2 cache memory. Why has no accelerator ever been done with L2 cache for Amiga?

thx

There was a time when I called it (in German) "Amiga tausendzweihundert", but "Amiga zwölfhundert" or "der Zwölfhunderter" sounds better .

A tilgte bit more complicated to do on Amigas than on other platforms ... because of the way the chipset-bus, DMAC and the Zorro-bus are working.
(Essentially you end up flushing the cache a lot and the benefit goes down)

An amiga-specific way would have been to incorporate a cache-controller into Ramsey and have just the Fast-RAM cashed.

I don't know, but I occasionally hear people call them 'oh four oh' processors instead of 'oh-forty'.

Which just sounds wrong when you're talking about the Falcon030, and people call it Falcon oh three oh. Or if you're lucky and they call it an oh six oh... :P

Yeah, I've always heard it as A twelve hundred.

In French I always said (and heard people say) "Amiga mille deux cents", which is the equivalent of "Amiga One thousand two hundred". "Amiga Douze cents" (= Twelve hundred) is theoretically possible but the X hundred (if X>9) is rarely used in French, except for historical dates and even then, the year one thousand XX format is preferred.

I think I was surprised the first time I heard some English-speaking person saying "Amiga twelve hundred" as I didn't expect it to be pronounced this way.

I always say oh two oh, oh three oh, oh four oh, oh sex oh etc.

Have I been wrong? Surely I can't be the only one...

[Daedalus]

Hmmm, I always said oh three oh, oh six oh etc., but I guess I'm in the minority. I now use a mixture of both, depending on the audience.

It was always Amiga twelve hundred though!

[Dustyarddog]

I have a genuine wb 3.1 licence and want to the software. I tried on Cloanto's website and could not work it out.

I emailed Cloanto, no reply.

How can I download the genuine copy.

I'm embarrassed as I can easily get illegal copies, but I cant work out how to get a genuine copy I paid for.
