ah, if it's just a certificate issue, cool
We had to deal with a lead issue when thomas was little, lead freaks me out. Mostly just reading about the potential problems is what freaked me out tho, not anything actually happening.
luckily, you didn't much have to. each command was tied to individual keys. Tho I had to retype every program, as I never got the cassette interface working right. I graduated to a TI99/4A and using hte university's PDP11 soon after getting that sinclair.
