What is actually IN a Unitor? Would it be possible to >fabricate something that does the same job? It so happens that I've just bought a Unitor-2 unit, and being the curious person that I am I opened it up of course ;-) (before people start asking what a Unitor is, I'd like to direct them to the Notator FAQ at the website (URL in my signature below) which explains what all of C-Lab/Emagic's add-on boxes do). Getting back to the Unitor-2.... It's a circuit board about 17 x 8 cm, not including the "fingers" sticking out which go into the cartridge port. At one end there's a cartridge connector "through port" which allows for the Notator SL or Creator SL cartridge to be inserted (unlike the older "Unitor-C" for Creator SL and "Unitor-N" units which had built-in dongles for those programs). At the edge facing opposite of the computer you have all the connectors: -SMPTE sync in -SMPTE sync out -Multiport (15-pin D-sub connector for "Steady Eye" or "Human Touch" units) -MIDI IN "2" -MIDI IN "3" -MIDI OUT "E" -MIDI OUT "F" The circuit board (double sided) is filled with the usual resistors, a few electrolytic capacitors, a few condensers, a couple of diodes, a 3MHz crystal, two opto-isolators (for the MIDI ports I guess) and of course several ICs. The ICs are of the following types: -M74HCU04B1 (2 pcs) -M74HC14B1 -T74LS04B1 -EP330PC-15 -M74HC299B1 (2 pcs) -M74HC590B1 -SCN2681AC1N40 In my opinion I would say that it shouldn't be too hard to "copy" for a qualified electronic engineer or similar. The biggest problem however would be bypassing the copyright issues. This brings us to the next issue: reverse engineering. Perhaps a similar working unit could be made, based on the Unitor-2, but without actually violating any copyright laws because it won't be a copy of the circuitry. But if the unit contains software (which I suspect one of the chips to do, perhaps the "EP330PC-15" which I'm guessing is a PROM), we might have a problem. Anyway, those are my observations and thoughts around this subject. Anyone else care to comment?
