For those interested in it, i have finally managed to replace an old 8-bit IDE interface with a CompactFlash driven by a “XT-IDE Universal BIOS” inserted in it's original BIOS. The trick is forcing the CF in 8bit mode and using the existing (but sligtly modified) XTA 40 pin connector.
The machine is an Olivetti PC1 HD (a NEC V20 pc). It's very compact and have an internal power sopply plus RBG video out.
The mod can be useful for every configuration that have internal XTA interface (i.e. Tandy 1000 models (1000RL, RLX, TL/2 and TL/3)). Because in not an Industry Standard (like AT-IDE) pinout may differ from mine. XTIDE Universal Bios made the difference overpassing original BIOS routine (you must have a free ROM space). The advantage is no ISA slot wasting (in effect the olivetti PC1 has NO internal ISA slot) and also a REAL QUIET, fast, compact, fanless PC clone.
I have made a guide for the mod at my facebook page:
