I'm sorry, I'm not really practical with all the standards that were used back then. I know that ISA was a standard card interface used by a lot of IBM clones in the mid-80s, but I'm not accustomed to power supply standards and so forth!

I've read about the IIGS monitor, but I haven't ever owned one, so I was not sure about the connector and sync/refresh rates it used, I assumed it must have been some sort of composite/antenna signal just by looking at the circuit output.

So basically, an industry specific monitor would be needed for that hack to work? Would it be possible to re-use it in some ways with more common CRT screens as found in TVs and old multiscan monitors? NTSC monitors won't like such a signal as you pointed out, but I'm wondering if it's possible to obtain something less-exotic than an industry grade monitor or if we are forced to do some post-processing to that signal.
