SCSItoIDE 1.10 07-Jan-2011 SCSItoIDE 6K Raw sector-copy program to transfer an Acorn SCSI hard drive to an IDE drive. You must use an IDE interface where you can change the hardware address, and set the address to &FC50 instead of the usual &FC40 so both the SCSI and IDE interfaces can be used. Once the transfer is done the SCSI interface can be removed, and the IDE interface address returned to &FC40.

I initially developed this patch using an emulated IDE device and Warm Silence's 6502Em. I then finalised the development using a hardware IDE interface.

I am considering adding RAM-Card support as well, supporting byte-wide RAM cards, such as Sprow's, and MMC cards, such as John Kortink's GoMMC.
