But nowadays, there are plenty of microSD ->  CF Type I adapters
that can be bought cheaply around the net.

Do these adapters fully implement a CF card, i.e. both memory and true IDE mode? This would require a microcontroller inside that converts the 16 bit parallel bus into SPI and does the protocol conversion.


Today, CF is only used for professional systems. High-end cameras, industrial data logging, high-speed applications. The advantages are higher capacity (up to 128GB), higher reliability, higher transfer rates, and compatibility to the IDE/ATA bus.

All this is not required for the Apple //c, so the consumer grade SD card would be more suitable here.

But remember: the SD specification with its easy-to-use SPI mode goes up to 2GB only. SD cards with 4, 8, 16GB are SDHC, not SD!
