Re: Hello from Canada

If your power supply is at 9.75V you could reduce the voltage down by adding a 1N4001 (50V@1Amp) in series with the input to
your computer.

Re: Improving Timex/Sinclair Tape Loading

A CD4001 does not have the same pin layout as the LM324 nor the same function

Re: Improving Timex/Sinclair Tape Loading

This is the order code for the LM324
Doing a google search with that code gave me this link: http://cpc.farnell.com/texas-instrument ... dp/SC13781
Obviously you received the wrong IC

Re: Improving Timex/Sinclair Tape Loading

You may have some connections that need to be checked for good soldering. Use a magnifier to see if they are soldered properly
(no cold soldered joins), check for shorts also with your wires connecting on the board.

What kind of desoldering tool did you use for your project. You did a nice job
