RPi XT IDE interface?

Mon Dec 08, 2014 11:39 am

So this thread follows on from an idea I had about scsi hard drives, but a question which someone might be able to answer.

Would an RPi be able to be used as an XTIDE (8bit IDE) interface? The Idea being similar to the idea of the RPI amiga diskette drive, a replacement drive, but for old machines with the 8bit IDE interface. Allowing the use of SD cards as effectively a modern hard drive that you could read on modern PC's.

I have an Amiga with a hard drive unit and that has an XT IDE interface, disks were only every as much as 80mb but sometimes you need more, so I thought this might be a useful idea!

Perhaps with a USB to IDE adapter?

Unfortunately the ide/usb interfaces are for a 16bit interface on modern hard drives.

What I am looking at is the problem faced with people using 8bit IDE which is found on some 80s computer systems including the Amiga and Some IBM pcs.

Apparently some interface can be constructed but drivers need to be written/installed to make them work, what I was more looking for is to build a replacement drive, with option connectivity.

They do exist and I've used them in an A1200 Amiga

SD card adaptor for IDE:

From the other thread you said you had an A590 (which came with either SCSI or XT drives inside),
here's someone who successfully used an IDE-CF adaptor inside an A590:

but feel free to engineer an RPi based IDE emulator !

See this is the critical thing, the guy on the amiga thread used a scsi to ide to cf, because the XT drive is 8bit, not 16bit like the modern IDE drives, seems the scsi to IDE adaptors are hellishly expensive, else I'd probably just use one of those.

So its actually adapting to the different interface. For XT pc someone created an ISA card that was 8bit to read CF cards, but that doesnt really solve the amiga bit in my case, nor adapting other devices like CD roms or whatever.
