Hi to All

Hi All,
I bought ZX81 on auction a few weeks ago and it flashed back my first contact with this microcomputer when I was 6-7 years old. I bought it as faulty unit, but with few touches it showed the "K" cursor on the screen. I managed to upgrade the internal memory from 1KB to 16KB, played a few demos and games that required 16KB memory pack and it has worked flawlessly since then.
My only concern is that the ULA is getting very warm quickly. I hope it would not fail soon.

Cheers
