Default Re: Gemini 80-Bus System

The voltage across C44, once charged sits at at just over 4.7V. Shorting this does not seem to change things. I can see the reset signal on the CPU go low when I do this. Also I can see C44 charge back up to 4.7V. Just for fun I checked the HALT pin and the CPU isn't in a halted state.

I do have the option of emulating an eprom using a Dataman S4, although I have never done this before so it adds anther variable. Whilst I ponder that one, I will disassemble the IVC ROM.
