Difficult to find PCMCIA memory card?

I could not find a PCMCIA memory card. Where can I buy it?

You might find some PCMCIA ATA FLASH cards online. But they are usually relatively expensive.
Please use a CF (Compact Flash, up to 2GB) memory card with a PCMCIA adapter.
"Type I CF" to "Type II PCMCIA" adapter is the one you will need.

Please format the CF memory card in FAT16 with your PC. PM1D or PM5D does not support FAT32.
