Help identifying what type of Amiga I have?

[Zeela]

Hi,

I have some sort of Amiga 500 at home right now.
To me it seems to be a regular A500 (not a A500+).

it displays the nice Kick 1.3 image of a WB disk when started. Ir boots WB 1.3 fine. So far all fine, a regular A500 you might think...

But when done booting and WB comes up I have around 900 kb free memory and the trapdoor expansion port is empty.
So its a A500 with 1mb memory but not a A500+? I thought A500+ ran WB 2.x?

What type of Amiga is this? And is there a way I can find out if the extra 512kb is chip or fast mem?

Please help

The case is like the first on above (the AMIGA 500).

So the case is not from a A500+.
And it has 1.3 chips... So the internals shouldn't be a A500+ either.

And there is no expansion in any of the ports. Not in the trapdoor and not in the side port (whatever it's called).

I tried to add a 512k expansion in the trapdoor, but that didn't give me 1,5 mb, just 1mb... And when i used the "off"-switch of the expansion card it left me with just 512k...

So I don't know what this beast is!

Its an Amiga 500. When you have NO ram expansion in the trapdoor, its reporting as 512K. And with the 512K Expansion ON you get 1mb. Amiga 500 :-)

Well, what I tried to explain was that without a ram expansion in the trapdoor its reporting 1 mb. When I added a ram expansion it still reported 1 mb and when I used the off switch of the ram expansion (still in the trapdoor) it reported 512k. When I remove the expansion it gives me 1 mb again.

Well, it's a puzzle...

Perhaps its an Amiga 500 with the 1 meg chip ram hack?

Hmmm... What's that? But it sounds like it could be!

Hmmm...

I found a site on the net
http://atzesgym.servebeer.com/~amiga/amigaemulation.de/multi/modelle_e/a500.php

That claims that there was three models of the original A500.

The A500, A500C and A500P.
Reading the descriptions it seems like I might have an A500P.

What do you guys think? If it's on the net it must be true? :-)

Do A500 Trapdoor expansions work in A500+'s at all?

If they don't why do the A500+ have trapdoor? Or it might not have a trapdoor? I've actually never seen a A500+ in real life.

Hi,

I took a quick look under the hood of my A500 this weekend.

What I found out was that it was a A500P.
There was a yellow sticker saying A500P attached to the place where the board revision and model are on the mother board.
