Sinclair ZX80 / ZX81 / Z88 Forums

I thought that might be the case. But since all I ever learned about electronics is from this group, I'd better ask.

I have measured wrong on the circuit, and updated the drawing.

Edit: This drawing is also wrong. I'll continue to measure.

Hi :) I try to understand the schematic of the Lambda Color Module. I've tried to match ICs on the picture and the schematic. There is one IC and drawings on the schematic I don't understand. Can anyone enlighten me? https://trello-attachments.s3.amazonaws.com/598af660300e0d55b35f5755/5a36e7929ce3cf...

... or Forth

Has anyone tried to have ZXblast and ZXpand connected at the same time. Can they coexist?

The game is MUCH better now. The timing is perfect. This little video shows the speed. BEWARE: All the corrupted chars on the screen is not the game's fault. https://youtu.be/LtdDbik4zxI (My theory is that ZXpand, which loads the game, has a problem with the Lambda 8300 ULA. Memory from the ZXpand i...

Few people have the color module. But Kai from ZX Team has made a schematic of it. So maybe one day a replica is made. It should work both for Lambda 8300 and ZX81.

Maybe your findings can be shared with Stefano knows what brings the delays.

Will it be possible for z88dk to create a universal Lambda binary, so there's no need for wall-lambda-rom1.p and wall-lambda-rom2.p?

So - is it your version-1-fix that slows the code? Or is your tool chain corrupted? Interesting!
