Title: A4000D 8mb chipram jumper?
Post by: tonyvdb on April 09, 2006, 07:14:51 PM
I was looking over the A4000 mb and noticed that there is jumper to switch between 2mb and 8mb chip. Is this posible to use and if so How? If I was to place the jumper to 8mb what would happen?

Look folks, if the Alice chip supported 4MB or 8MB of RAM, it would do that right out of the box. Honest.  There's no reason to change around any PCB jumpers, it's only going to get you in trouble. NEVER EVER mess with a PCB jumper you don't understand, even if it's labelled "SEX AND FREE BEER".

It has almost the same effect as setting the "free sex and beer" jumper: nothing. This jumper was "for future use", but 8MB chip-RAM custom chips were never developed due to commodore's bankruptcy.

Bye,

Dave Haynie designed the motherboard wrong.
So that jumper does not work.  :bigcry:

I have always wondered if Dave Haynie did that by accident or on purpose or because the Islamic Terrorist Mehdi Ali told him to do it.  :-?

Its a shame, If they had made a 8mb chip the Amiga would have been able to use much more suphistocated graphics and modes.
Oh well it was a nice dream :shrug:

Haha, Dave Haynie is a great man, every time I see some photo of him or read something he said, it must be related to beer somehow. Simply cool.

@tonydb

Its a shame because Paula really needed that 8MB so she could sing to her full potential.

Paula is my fave Amiga chip. :love:

Just the 8Mb wouldn't have cut it for improved graphics and modes. A better and faster custom chipset would have been needed too. AAA?

Anyway WinUAE does have the option to use 8Mb ChipRAM.

At least not until some Amiga-loving millionaire buy rights to make AAA chipset and finish it's development process... ;-)

BTW: who has those rights anyway? (http://autokacik.pl/images/graemlins/hmm.gif)

@ChaosLord:
BTW, Paula is the only chip never ever changed from 1985's A1000 all the way to 1996's A4000T - allegedly the schematics were lost in the mists of time...

Can I just ask, wtf does the Islamic Terrorist Mehdi Ali have to do with David Haynie having placed this Jumper on the Motherboard for future chipsets?

Can I also ask why all you Americans allow yourselves to be blinded by bullsh*t?

Go read, watch ALL the movies & inwardly Digest these links before even considering answering this post.

By touching that jumper I believe (IMHO here) you could leave your A4000 to the faith of the -ol' 1200 and lose downward compatibility with games like you never had one.

If only I could win the EuroMillion ! I would sure buy the rights of AAA chipset, and add 8 channels audio (PAULA x2) plus 2 SID chips (remember the C64DX/C65 :-) ) so that she would keep it's old school features !  ;-)
