Hello, CHRV CHR> What nonsense - Turbo2+ uses both an SD and a hard drive on one CHR> cable, and the Ham controller supports this perfectly CHR> (let's remember CDWALK from Vega). I don’t understand how the scheme differs CHR> using only the hard drive and the hard drive usage scheme CHR> disk and SD simultaneously. Apparently we don’t know the hardware at all. Yes, yes - master/slave. CHR> All IDE devices have a controller directly on board, and CHR> communication with this device occurs at the level of writing commands to registers CHR> IDE controller. Selecting a device involves writing a bit to CHR> specific case. The schemes are similar. And if you recall my idea, which I developed in the previous message.. on the topic of internal and external ports.. let’s say an internal hard drive CF or 2.5' and quite naturally an external CD. If there are an abundance of ports, then you can simultaneously write to both ports at once. Add. the register is already on the external CD. Again It is necessary to study the standard diagrams in order to minimize modifications to the device.
