A1200 PCMCIA and IDE Info
« on: December 09, 2007, 07:15:29 PM »
Hello tech gurus,

     Does anybody have information about the registers used in A1200 IDE and PCMCIA interface ?
     I have four basic doubts:

     - Are these registers 8 Bit ones ?
     - Are they Acessed as 16 or 8 bit in the bus ? Gayle has only a 8 bit data bus but it could still be 16 bit aligned, as the CIAs are.
     - How the memory areas reserved for these interfaces work ? I know where and what they are, but I don't know how they behave
     - Is the 4 meg space reserved for PCMCIA accessed as 16 or 32 bit ?

     Thanks !

The PCMCIA port on the amiga is 16bit

The best site I can say to look at is Ian Stedmans, the A1200 function spec doc has a bit of information but as for answering your questions I will have to pass, sorry.
