- Does anyone remember a plug-in device called the "Computer Saver"? I
- believe it was sold by the Grapevine Group before they went belly-up.
- Installed between the supply and the computer, the Saver was supposed to
- prevent a failing black-brick C-64 power supply from torching the chips
- in the computer. One way the supply fails is by overvoltage output (more
- than 5 volts DC) when the regulator shorts out. The Saver must have had
- a circuit to sense the increase and cut the power off.
- Grapevine is gone, and I haven't seen the Saver advertised anywhere
- else since. Is it still made? Is there any interest in a device like
- that? People are still using the original supplies and risk damage to
- their computer chips. I believe I could make a Saver to sell for less
- than $20. Any interest?
