problemas con la PCMCIA
Q. What causes the conflicts between PCMCIA cards and A1200 RAM boards?
A. The 68ec020 used in the A1200 can only address 8 Megs of FAST RAM. The PCMCIA slot uses 4 Megs of this address range whether you’re using a PCMCIA RAM card or not. This means that only 4 Megs of addressing space is available for a trapdoor RAM boards. Newer accelerators will solve this problem as 68030 has its own larger address range. Some older accelerators use 4 Meg of the 68ec020’s addressing range so the same problems will occur.
