I decided to flip the output on the ZX80 to make it output inverse by default:

Now I can use my jumper fully installed for inverse out of the Z8-CCB - normal black on white - so I am less likely to have the jumper fall off during normal usage :)

My other ZX81 arrived yesterday and came with ZX81 16K RAM pack so I thought I'd try it on the ZX80:

It fits like a glove :)

Something that the memotech didn't do at all!!!

So I did a little internet search to remind me of how to check the RAM and it came up with this:

The result being:

So happy days :) I'm tempted to paint the RAM pack white to make it all match :)
