OK, so I've been browsing Vesalia.de and AmigaKit and all I can find in A600 ram expansions are the A602 and A603, which are both Chip RAM expansions.
I really want Fast RAM, though, 1MB chip is enough for me. Problem is, I haven't seen any Fast RAM thingies for the 600. Where are they?
I know I can use a PCMCIA SRAM card, but that's not really an option because:
1. I already use a PCMCIA SD card adapter and want to continue using it.
2. SRAM cards are hard to find and way too expensive when they do show up.
3. I heard that PCMCIA-based RAM really isn't so fast and actually can slow the whole system further down (not sure how true this is, though).
Are there "proper" RAM expansions like the A602/A603, and if not, could either of these two somehow be altered to become Fast RAM instead of Chip RAM? Even 1MB would do it for me, though 2MB would be really great.
Note that I don't want to end up with Slow RAM either, i.e. RAM seen by the system as "fast RAM" but really running at chip-RAM speeds.
Ty in advance. 
As far as I know there is no way to add fastram without using the PCMCIA slot, why not use a 4GB CF card with a 44pins IDE to CF adapter? Then if you want to transfer files between a Windows machine and your amiga just put the CF card in a CF reader on your PC and mount it in winUAE.
Tho tests shows that adding fastram to a A600 do not slow down your system but ingrease speed, but the 1200 will be slower.
