of treating the A12 line and/or the enable lines… another last-minute kludge?
appears that this system had a neater, more-cunning approach to it, though. That in turn implies that it might have been one of the later systems and not a pioneer. The MPT-03 system designers first found a way to do it, and they just copied it. • The pin layout of the MPT-03 just makes so much more sense, compared to this system’s layout. This was an obvious attempt to change the pinout, on one of the manufacturer’s parts, to be sure that the systems were mutually incompatible. It looks like the Ormatu designers intentionally avoided using the same pins that were used on the MPT-03 system to hook up Power and Ground? The way they set up these cartridge circuit boards, no matter which way you inserted one of these into an MPT-03 system, one of those two required pins would connect to a pin that simply goes nowhere, internally. And with those pins disconnected, it won’t work. • If you look at the large cartridge library of the Ormatu system, as seen in their nicely printed, full-color c
