Title: Wanted - Memory expansion for A1200
Post by: BGoins12 on March 31, 2015, 04:57:39 AM

Looking for a fairly cheap memory expansion card for my Amiga 1200. I have been searching all over and have not been able to source one at a reasonable price. The only one I found was local and the guy wanted $100 for it.

I'd like to get a 4MB one, or even one that doesn't have a memory module installed (I have tons of 4MB 72-pin SIMMs).

I've been pointed to buying an ACA-1233, but I definitely don't plan to spend $200... I don't need anything like that as I just need the extra memory to play 2 games that don't work with 2MB.

If anyone has one, PM me.

Thanks!

There is a problem with the A1233 and it doesn't work on certain motherboards. You need to do some soldering to get it to work. Amiga Kit should put that warning in bigger letters.

Ah, didn't even see that notice at all. I don't plan on buying one anyway unless I happen to have the extra cash to do so. My board revision is the earliest I think... 1A.

What you're talking about is a fault with some A1200 motherboards not the A1233. Timing fixes need to be applied, there is an in-depth explanation posted already in multiple places so I wont get into it again.

You can fit any cpu card to a 1A without any modifications to the motherboard. So should you decide to go for a cpu card in the future then you're all set. :)

As a last resort you can get a 4MB SRAM card for the extra ram if ram is all you need and you can't find any cheap trapdoor expansions. Now a SRAM card over the 16bit PCMCIA bus will slow down the A1200 a bit but at least you have enough ram.

Ive seen 2-4MB SRAM cards compatible with the A1200 go for quite OK prices if you dig around a bit.
