Questions - Setting up a SRAM board in S-100 / Altair system?

Well, that's oen form of 'sorted' I guess... More seriosuly, I have a healthy respsect for the mains. I am not afraid of it, I work with 230V (nearer 240V, actually) mains most days. But I know it can also cauase enough current to flow through me to kill me [1], so I don't give it the chance. What I mean by that is that I do not accept anything 'dubiious'. Even i I know about it, sombody else might make a mistake. In your position I would sort out the wirign ASAP, make sure all socket outlets have groudn wires, and so on. [1] As I was taught many years ago 'It's the volts that jolts but the mills [2] that kills' [2] milliamps, of course. Even woese than having no earth to a socket is the situation where a numbero f ccoekt outlets ahve the earth pins all linked together but not then conencted to ground. The reason is that if there is a leak on anything plugged into one of said sockets, the metal cases of things pluggedi nto the oterhs will become live. And yes I did once come acorss such a situation. As soon as I pointed it out it got fixed -- ASAP. -tony
