I managed to get good signal from that pin in the photo using a 100nf capacitor.You might also use a 100k resistor instead.

Brilliant, I really appreciate that!

I have plenty of 0.1uf electrolytic caps which seem to work fine also on other boards

I need to check my tape decks to find one with the same board.

Not sure if it helps, just now took a picture of the under side:



I can't even find a schematic for it here: http://www.zimmers.net/anonftp/pub/cbm/schematics/datassette/index.html

If there is another method of finding the pin I am happy to give it a try, I don't have an oscilloscope, I will make sure to share the answer here if/when I find it.

Sorry for the bump, anyone got any ideas on the board above before I buy an oscilloscope :)

I just got another old one out of my junk box, the heads are gone on this one, it shows absolutely nothing when running any tape head alignment so I might as well do the same to this one as it will never read tapes again.

I cant seem to identify the left on it though, any ideas?

That's a grand job mate  ;)
Thanks for posting your results.

Thanks, I don't suppose you are aware of anything like tapdancer or CDT2WAV (Amstrad cpc464 equivalent mod) that runs on PC/Windows (or linux) ?

It would save a lot of effort and steps if I did not need to convert every single game to wav first.

Ok all working:




Little youtube video pre-cable tidy:


I hope that perhaps helps someone in the future.

actually, I re-read everything and found more info in this post too.

I did not have any ceramic caps so I put a 0.1uF electrolytic capacitor on instead, positive side soldered to the board.

This time it came up saying "found file"

However it did not ultimately load even the intro screen, i will experiment a bit further and update for other future people.

Thanks from the future :)

I was looking for a similar board to mine after finding another guide and found this one, is a 100kohm resistor required on the left for this as other guides have suggested?
