If the Timex uses 4116 RAM, it probably has a little switch mode power supply to generate the -5v/+12v supply to the memory. It's probably the coil making that noise. The Speccy does that too.Problems with TS2068sI bought 2 TS2068s, and this is what's happening: 1st computer: -The tv output doesn't work. The composite video output does* -The '7' key is dead.…
Lots of advice here. Thanks guys.
Regarding the coil, shouldn't both TS2068s do the same noise then? One is completely silent, and the other one has a loud hissing noise that you can hear from 1ft away.Problems with TS2068sI bought 2 TS2068s, and this is what's happening: 1st computer: -The tv output doesn't work.
