Well, now that you've got this far you could (temporarily) repair this machine (Henceforth known as ZX81 #3) by fitting the lid / keypad from ZX81 #1, the one which has the ULA problem. (Maybe you've already done that, otherwise how were you playng Asteroids)?

That will give you all the time in the world to attempt the ULA change, as you can be using ZX81 #3 while you fix ZX81 #1 at a relaxed pace.
