Default Re: I found it! A very sorry looking MK14.

Unfortunately it's the top I'm having the most trouble with !.

I've cut so many tracks around ICs 16 & 17 it's difficult to see what they were originally. I'll probably have to use the circuit diagram to work it out.

Regarding the 'official mods', I'm not sure if I did them as per the instructions posted in this thread.

These are the instuctions I followed, from the 'Instructions for Revised Monitor' leaflet. There is no mention of swapping C6, and mine is still in it's original postion. These instructions applied to the Single-Step, and are described as resolving a conflict between ROM data and status during NADS.

I'm not too bothered about the duplicated ROMs anyway. Micky is not going to be used for any further experiments, I've got Vicky for that.

Cheers,

Buzby
