Luke,
I took a quick glance at the Wikipedia entry and saw what I thought was an error and I will fix the problem if you can confirm that I understand the situation correctly.
The wikipedia article says the following:
"""
There are two different physical profiles of EOMA68 (based around the legacy PCMCIA classifications):[2]
54 mm × 85.6 mm; 5mm variant (Type II) 54 mm × 85.6 mm; 3.3mm variant (Type I)
Type I is reserved for up to 1366x768 RGB/TTL video output; Type II is reserved for up to 1920x1080 RGB/TTL video output, on the basis that a Type I 3.3mm card may fit into a Type II 5.0mm socket but not vice versa. Thus, a module with a lower-capacity video output will physically be prevented from being used with incompatible higher-resolution devices, preventing any possible confusion about interoperability.
type I 3.3mm.... no! that's wrong! well spotted. i believe i added that in a hurry without checking.
It's worth pointing out that the specification on elinux.org is
Under "Physical Dimensions" it says there are two valid sized, Type II which is 5mm and Type III which is 8mm.
Under "Requirements for RGB/TTL" it refers to 5mm and 3.3mm cards, but not 8mm.
