I made mine from a Kit which guess what - didn't work! So had to go back to Sinclair - their diagnostic helpline asked me to put my finger on the ULA and I said "Ouch its hot" - so he said - hmmm not that then. Turns out the Z80 was faulty so they repaired it FOC but, it was several agonising weeks waiting for it to come back, just reading the manual. I still remember the feeling and love looking at my original manual with its pencil notes.
