My A600's PCMCIA slot was so tight nothing would fit in it, so I took the motherboard out and refitted it in the bottom half of the case with a card in the slot and screwed it back in, and now it's fine, a little tight but firm, not impossible.
Actually, its good to do that same procedure on the A1200 with the accelerator before I did that my accelerator was sitting at an angle to the MB.
Never noticed any issues with the PCMCIA fitment other than the fact that I have always found it odd how far the cards stick out. I just tell people it is because Commodore engineers were trying to achieve better wireless signal strength
