Hi all, Guiseppe,
Yes, it's possible, I've done it four or five times successfully and it's not dangerous in any way... (ROM PAC -> PC parallel port dump, I mean ;-)
No risk is assumed, both your ROM PAC and your PC are always at a safe working zone.
Anyhow, the range of PC parallel interfaces working voltages are so wide that only three out of seven tested machines handled the process without errors, a single chip (or may be a single transistor) will solve the trouble, as it's located only in the ISA line INPUT/OUTPUT separation, but I've been quite busy these days, and assumed that this "micro-project" of mine was of little or no interest to most users. Actually most ROM images are (as J-F has pointed out) at a "well know" place.
If your're interested please mail me, I'll gladly send you the schematics and the dumping utility.
Cheers from the Canaries.
Diego.
P.S. For the sake of precision, this procedure DOES NOT work with Clonix modules, only with original ROM PAC's.
