Ram for A1200... amikit.com dont have.

[Tiago]

I went to amikit.com... they dont have A1200 ram expansions... only for 500 and 600.

I was expecting th 600, but i bought the 1200, so i dont know many things about the 1200....

How can i expand memory, do i need to by a board to (put on a bay port?) so can i put the memory modules? What kind of modules?

Can i use the pcmcia port to put memory cards? Will they word the same way as a module ram?
What memory should i buy and were since amikit dont have modules?

Thanks

The A1200 trap door slot is a full system expansion slot, not just a ram expansion slow in the case of the A500 and A600. It allows you to connect expansion cards for many purposes including full cpu accelerator cards.

You can get 4 and 8MB ram expansions for the A1200 trap door slot, but they are not really worth it compared to buying an accelerator card. Only consider these if you are on a tight budget because if you later want to upgrade to a faster cpu you won't be able to continue using the ram only expansions.

The most common way to add more ram to an A1200 is via an accelerator card as most have 1 or 2 SIMM ram sockets built in. The best accelerator card for the price is the Blizzard 1230 mkIV. This contains a full 68030 CPU running at 50MHz, plus the ability to add ram. Most people add between 32MB and 128MB of ram to accelerator cards.

SIMM ram sockets ... like pc ones?

What about the pcmcia, can i put memory thru there?

[Harrison]

You can use 16bit PCMCIA memory cards of 4MB and 8MB in the A1200's PCMCIA slot but I don't recommend it. It will slow the Amiga down as it is only 16-bit ram, and so the A1200's CPU cannot address it at full speed. Always stick with the trap door expansion slot for ram upgrades.

And yes, most A1200 accelerators use the older PC style 72pin SIMM ram.

And for running OS3.9 if i use pcmcia memory will it be full funcional ? Slow, ok, but will it work?

and it has to be any kind of special memory pcmcia? Or a vulgar one does the job?

[Harrison]

Don't use pcmcia memory. That is my recommendation. As well as the memory slowing down the system there is also a conflict with 4MB or more memory in the PCMCIA slot with other parts of the system.

For OS3.9 you will need a proper accelerator card with at least 32MB of ram to run it properly, plus a decent sized harddrive (1GB+) installed. I wouldn't try to run OS3.9 on an unexpanded A1200.
