I have a fully tested Kingbyte pcb and enclosure for sale. You can use this to make your own Disk Dual. The Disk Dual is an add-on for the Super Wildcard DX2. It supports IDE CD-ROM, IDE HDD and CF cards (adapter required for CF cards). CD-ROM has to be jumpered as a Slave device. HDD as a Master device. I've tested 2x, 4x and 8x CD-ROM drives which work flawless. I've also tried a 40x, but it failed to load roms. HDD/CF is limited to 2GB and FAT16. Please be aware of FAT16 file system limitations, such as 8.3 filenames, max 64 files per folder and so on. HDD and CD-ROM can be connected at the same time. However if you want to read files from HDD, make sure that no CD is in the drive. The enclosure has scratches and a poorly made cutout for the CF card reader. price: now 30 Euros worldwide shipping costs including tracking: EUR 6.20 for pcb only EUR 19.50 for pcb, psu and enclosure (it's very heavy) CF-Card+adapter, HDD, CD-ROM are NOT included! Example with a CF card reader (a CD-ROM can be attached above it). CF card reader NOT included!
