Do any of the RAM chips feel warmer/hotter than the others? A hot one could indicate that it was faulty. You could try piggy backing a good chip on the RAMs in turn, there is a very low chance that it might help you identify a failed RAM. If (when) the above don’t help, then what to do? As you say, ...

Hi Roger, Welcome to the forum! That monitor should be OK, you say that it’s the only one that you have, but most TVs have a composite video input, usually with a yellow phono connector, perhaps you have one like that that you can try too? You could also try the TV output if your TV has an RF (coax)...

If you are talking about the numbers sold for use in micros, then probably, but Z80 was hugely popular in industrial/control applications and I'd argue that it made a bigger contribution to the world

Did your head grow heavy too?

Did you have to stop for the night ?

And why look at a different FPGA board? Down to me I’m afraid . . . . . I’ve had lots of problems with procuring the Cyclone Ii boards. There were shortages on the back of the Covid thing, but availability is improving. The biggest issue though is the variable quality of the boards from the Chinese ...

Now, that’s more interesting

Let's recap the clues: You have a custom ROM that does away with Retro mode. There's an FPGA dev board plugged into it that has a ribbon cable coming out of it, but I don't see where it connects. Going to need more to go on, Martin, as this Sherlock is struggling. Accurate, but nothing really of no...
