+# AppleIISd
+SD card based ProFile replacement for enhanced Apple IIe computers
+
+The **AppleIISd** is an SD card based replaced for the ProFile harddrive. In contrast to other SD card based cards this card does not replace a Disk II drive. Data is saved directly onto the SD card, it is not via images on a FAT system, like on other cards. The SD card is read- / writable with CiderPress.
+
+A CPLD is used as a SPI controller and translates, together with the ROM driver, SD card data to/from the Apple IIe.
+
+The assembler sources are written in Merlin-8.
+
+## Features
+* up to 128MB storage space (4x 65535 blocks), currently 32MB
+* ProDOS driver in ROM
+* Auto boot
+* Access LED
+* Write protect sensing (not yet)
+* Card detect sensing (not yet)
+
+## Requirements
+The AppleIISd requires and has been tested on an enhanced IIe computer. The ROM code uses some 65c02 opcodes. ProDOS versions 1.1 to 2.4.1 seem to work. 
+
+## TODOs
+* Support more than one partition
+* Implement card detect and write protect sensing
+* Use 7MHz clock as SPI clock
