There's an alternate world where we still got IDE but there were never IDE cables.IDE is just the ISA bus across a tiny cable to talk to the controller on the drive PCB, so cables are just there for convenience.We could have just been mounting hard drives in ISA slots!And we did! HardCards! But we could have had it more.

@foone all those years and I just discovered IDE is just the ISA protocol.

@rogersm it's also called ATA (as in, the later Serial ATA, SATA).ATA is AT Attachment. As in, IBM AT: it's the 16bit bus of the IBM AT computer, released in 1984

@foone And then we got PCIe NVMe's and came full circle https://commons.wikimedia.org/wiki/File:Intel_SSD_750_series,_400_GB_add-in_card_model,_bottom_view.jpg

@foone did you just kinda say like "IDE is the back-then equivalent of m.2 just using ISA instead of PCIe" ? lol

@foone I saw some at IndyClassic. Really interesting things!

@foone Ah, I used to install those in customer computers back in my first job at an IBM dealership. Specifically, original IM PCs, which brings me to the point that the hardcard in the picture has an 8-bit ISA bus, while IDE is 16-bit...

@malwareminigun It did over IDE! By that point the drive controller was PCI, so it had much higher speeds. The controller is just talking Very Fast ISA over the IDE cable

@foone So a malicious IDE drive would theoretically be able to perform DMA attacks against the host system? 🤯

@fooneSo ... the IDE cables were just the PCIe risers at that time? 🤯
