PCMCIA A1200 myths

[psxphill]

how this can be possible if I have the card with 8mb ram and professedly the turboboard is pcmcia uncompatible if more of 4mb ram is used?

Only PCMCIA RAM cards should cause a conflict as PCMCIA IO cards are mapped to a different area of memory outside the 8mb allocated to fast ram.
 
000000 to 1FFFFF 2 MB Chip RAM(or system ROM overlay)
200000 to 5FFFFF 4 MB Zorro II expansion space
600000 to 9FFFFF 4 MB Credit Card memory if CC present
AOOOOO to A1FFFF 128 KB Credit Card Attributes
A20000 to A3FFFF 128 KB Credit Card I/O
A40000 to A5FFFF 128 KB Credit Card Bits (similar to CDTV)
A60000 to A7FFFF 128 KB PC I/O

I think is a serious bug in Kicstart 3.1 or commodore did it purposely to avoid conflicts with pcmcia ram cards......anyways was a stupid mistake cause lots of devices works ok

I might be wrong but I seem to recall reading in the 3.1 release notes that come with the NDK that they did do it on purpose.
 
It was a stupid mistake because PCMCIA IO cards should be 100% compatible with 8mb of fast ram in the Zorro II space. It's only PCMCIA RAM cards that would ever have a problem & why would you bother with those if you had >4mb of RAM anyway?
