I am in south wales!! I can just pick it up! Where are you? Cheers mate

[SWAUG]

Cardiff.

You are welcome to pick up. What Amiga do you have? 2.05 is from an A600 but should work in an A500 too.

Whhoops: just noticed that you have an A500... should be OK in that.

Are A1200 Kickstart 3.0 chips utterly utterly worthless, btw?

[LinchpiN]

I dunno, i have 3.1 in my 1200, if thats what you mean :-) I dunno what the max kick in a 500 can be.

[alx]

IIRC an A500 can take everything including 3.1 (interesting how the latest OS would work fine on a 7 year old computer back in those days!) Aren't there two types of Kickstart chips (single/double ICs) though?

[Indoro]

Yes, the A500 uses the same ROM as an A600 would, or an A2000/A1500 would. The same is true, to a degree for A2000/1500/500 ROMs over V3 for the A600. (The A600 requires V2.05 or later).

So, if you have a ROM for an A600, it will work in an A500, or any A2000 series (A2000, A1500, A2500. You can also use this in a CDTV, but you will lose much of the functionality of the CDTV in the process.

[mikeymike]

the KS chips in an A500 (and A2000 as well?) are a different size IIRC...

[PaSha]

Here goes, AFAIK correct, but please correct me if I'm wrong:

The A1000 uses kickstart disks.

A500, A600 & A2000 (inc. A1500/2500) use the same kickstart chips, one single chip. The A600 requires atleast v2.05 (v37.300) in order for the IDE and PCMCIA to work. Kickstart 3.1 version number is v40.63.

The CDTV use the same chips as A500/600/2000, but require two additional chips for controlling the cdrom drive and providing the boot anims.

The A1200 uses two chips unique for the A1200. Kickstart 3.1 version number is v40.68.

The CD32 uses one single chip with Kickstart 3.1, boot anims and cdrom control, v40.60.

The A3000/A3000T uses two chips unique for the A3000/A3000T, Kickstart 3.1 v40.68.

The A4000D uses two chips unique for the A4000D, Kickstart 3.1 v40.68.

The A4000T uses two chips unique for the A4000T, Kickstart 3.1 v40.70.

The walker is said to have used Kickstart 3.2

(semi off topic. not really): /me is looking for 3.1 roms that are cheapisher than what soft hut has, any one know where to buy them? Or actually, 2.x sounds better than 1.3 to me. with what KS/WB combo can the WorkBench show all of the items in a folder even if they don't have an icon?

[Argo]

McGoo, You did it again!

Do it yourself upgrading, isn't it fun?

I've bent pin on a ROM Twice! Fortunatly, they didn't break off. Though I did trash the socket when I upgraded the Angus in the A500 I had. Gotta keep those computer repair shops in business.

[mikeymike]

I've bent pin on a ROM Twice!

My God! What did you use to get the chip in, a sledgehammer? The pins on the KS chips are like 6ft across in comparison to x86 CPU pins, now they're on the fragile side (though I've managed to unbend several pins on a badly-delivered x86 CPU before, that was fun, the CPU still worked) :-)

[mikeymike]

@ PaSha

So basically, yes, my KS 3.0 A1200 chips are useless :-)

Although I wonder whether it would be possible to cheaply build a bridgeboard...
