If they write READY on the screen on power up, it’s ROM version 2. This ROM supports the Lambda Colour Pack and has color commands in Basic.
Version 1 of the ROM is more equal to the ZX81 ROM, and only have a blinking cursor on power up.
Lambda 8300/Power 3000 box content?
Re: Lambda 8300/Power 3000 box content?
Understood. All 3 are v2. What about the oddness in the lower screen area? Is it likely to be cured by recapping?

I’m no expert in electronics.
When I had trouble with the picture it was due to timing with the RAM.
Have you tried with all the RAM Packs? They may give different pictures.

I re-capped one of them just now, made no difference. Tried without Ram pack, no difference. I suppose it's quite likely it could be the TV so I'll try another.

Yes, it was the TV! I have 3 working Lambda's.
