The device arrived today. Very dirty and with a strange power cord, that would not fit.
I us d a regular power cord and the device switched on and is surprisingly fully functional.
Gave it a good cleanup and bought some gel.
Well, it is the veterinary version, but I was able to watch my heart working.
I can't really believe that I own this now, as it was a real bargain.
Need to learn how to interpret the images now...
Sadly this is a device from 1998 and as such, it does not have a Harddisk.
I did not dismantle it fully, too many screws and no real reason to do so. I think that the clinic/Human version has a different ROM set. So it seems I won't be able to hack or patch the FW to activate different modes beyond the veterinary ones.
Cool device, though.
