Well, the tests were great on non Japanese computers but I couldn't make it work on the:
1-SANYO WAVY 70FD (Japanese MSX2+)
2-SONY HB-F1XDmk2 (Japanese MSX2)
It worked on the two Philips MSX2 (PAL):
1-Philips 8245: it works on DS1 and MTRON
2-Philips 8280: this model has two disk drives. When both unplugged, HxC works on both units on DS0 and MTRON. When the first unit is plugged, the HxC cannot be used on the second one. On the contrary, when the second one is plugged, the HxC works on the first one on DS0 and MTRON.
I don't know what's the problem with the Japanese MSX models.
By the way, I just opened a Twin Famicom and saw that the 3 inch disk drive has a connector with 17 pins:
Does anyone have info about the pinout? Could it be possible to load FDS images?
Warning: according to this page ( http://firstname.lastname@example.org/msg07579.html
) pins 1,2,5,7,9,11 are +5V on the SANYO and on the hxc floppy emulator it's the ground ! So you must cut these lines on the fdd cable to avoid shortcut!
Before plugging the hxc to an msx you must check its pinout, even if it uses a 34pin connector: the pinout is often non-standard on these computers !
Regarding the Twin Famicom , the hxc floppy emulator don't support it at this day, but i am interrested by adding its support (it's a very special disk drive). can you send me some fds ?
