I had this spare motherboard but the
CPU appears to be busted
I left the original ROM in place to test
In the end I plundered my box of spare
chips and replaced both
Working.. so I decided to swap back the 3.1
Now working with the 3.1 ROM
OK rewind the tape and when I was
swapping out the ROM did you spot the
stupid error I made
Still haven't spotted it ?
The CPU is the wrong bloody way round
D U H
All fixed now... The inset is correct
And trust me .. if the little half moon
isn't at the bottom then it aint gonna work
What may fool you is that the writing on
the ROM and the writing on the CPU are
not both the same way round. Also the
ROM chip has the ROM half moon at the top
