Sorry for the late reply. 

I am relatively sure that I can now read the complete content of PCMCIA cards with Hammer from physical MP2x00s. I will try to post a step-by-step description how to do that so that everyone with a PCMCIA card and some patience can secure the content of their cards.

PCMCIA cards are usually 85.6 by 54.0 mm. Later micor PCMCIA cards and express cards were smaller. CF cards are smaller and similar. The length of the card doesn;t really matter if it is for internal testing only, and if it sits in a case, it can still be inserted and ejected just fine. Maybe Apple just uses raw cards here that are big enough for the RAM chips.

I had to check the PC Card spec to prove to myself that they were actually a thing. Also, that the Wikipedia article on PC Cards incorrectly states that all PC Cards were the same length.
